2008 Dodge Avenger Crankshaft sensor loacation

Showing 5 out of 5 Posts
Question From epbomb1 on 2008 Dodge Avenger Crankshaft sensor loacation

Can anyone provide me a picture or diagram of where the crankshaft position sensor is so I can replace it? I have error codes p0315 and p0335, theyre both Crankshaft position sensor errors. Need to fix this pronto, someone please help!

Response From Hammer Time

Apparently you want us to guess which engine you have?

Response From epbomb1 Top Rated Answer

Sorry I forgot to post the engine, it's my girlfriend's car. It's a 2.4 L 4 cylinder engine, I had a diagnostic test run on the engine, it gave me error codes p0315 and p035, the first being 'crankshaft system variation' and the second being 'Crankshaft position sensor A circuit malfunction.'

Response From Hammer Time


Response From Discretesignals

How did you come to the conclusion the crankshaft position sensor is the culprit? I'm sure you tested power, ground, and the signal circuits before condemning it.

Question From 440mag on 1994 dodge trk 5.9/4x4 amt no fire from coil

1994 dodge trk 4x4 5.9 no fire from ign coil???440 mag

Response From Hammer Time

Does it have injector pulse?
Does it have power to one side of the coil when the key is first turned on?

Response From 440mag

1994 dodge trk 4x4 amt 5.9/yes it has batt voltage to primery,but when you crank it looses voltage after about 2 seconds!!

Response From Hammer Time

How about the injector pulse?

Response From 440mag

1994 dodge trk 4x4 5.9 atm no inj. pluse!!

Response From Hammer Time Top Rated Answer

I would highly suspect the Crankshaft position sensor. The EEC relay is powering up for initial prime but not coming back on likely because it's not seeing a tach signal.

Response From 440mag

1994 dodge trk 4x4 5.9 gas atm;i`ve already replaced crk & cam senors nochange??

Response From Hammer Time

Then your going to have to get into some in depth troubleshooting with a scan tool to determine just what is dropping out and whether that crank signal is being read by the computer.

Response From 440mag

1994 dodge trk 4x4 5.9 no fire from coil; yes your right! mitchell manual say`s crank senor when check with a ohm meter on b&c termials should be no resistance checked new sensor same resistance so i check another sensor and it`s the same but they test good on sensor tester for pulse??? thanks for your help!!your friend 440 mag!!

Question From DRock on won't crank

2003 dodge grand caravan will not crank new pcm purchased no change next move is going to change crankshaft sensor what do you think anyone had similar problem

Response From Discretesignals Top Rated Answer

Crankshaft position sensor won't cause a no crank.

First thing you need to do for a no crank condition is to have the battery tested and make sure your connections on the battery are clean and tight.

If the engine was cranking, but wasn't starting, a missing crank sensor signal would be a possibility.

Response From DRock

THANKS FOR ANSING the car was starting up in the beginning but idiling poorly was getting codes rigrt rear sensor lean mixture also tps code and map sensor codechanged them all but the car got sicker that when all the no turning over stiff started

Response From Discretesignals

Not sure what you mean by "all the no turning over stiff".

Does the starter motor spin the engine?

Response From DRock

yesbut won't crank that is what Imean by turn over

Response From Discretesignals

Ok the wording is confusing this.

Crank means the starter is engaged and spinning the crankshaft

Start means the engine is cranking and the combustion process begins.

Response From DRock

was told I had fuel and spark

Response From Discretesignals

So the engine is turning over, but it isn't firing up??

Response From DRock

correct
in the beginning I got codes po203 po300 po302 po304 po305 po108 and po122 and 2 codes not in manual po1478 po1193 all having to do do emissions

Response From Discretesignals

OK...now that is resolved...wheew.

Which engine?

Any trouble codes stored in the ECM?

Who said it has spark and fuel? What is the fuel pressure? Did you check for spark on all cylinders?
Did you check for injector activity while cranking?

Response From DRock

the mechanic Itook it to then the head man says my pcm no good Iget one install it nothing new call pcm people tell themis still won't start tell me put crankshaft sensor in

Response From Discretesignals

Did you just slap a PCM it in without programming it?

Response From DRock

told me it was all done part of the payment Igave them the vin number the mileage and the pcm number

Response From Discretesignals

You need to have this vehicle diagnosed by a licensed reputable repair shop. From your posts it sounds like a bunch of flunky monkeys are playing swaptronics instead of properly diagnosing the problem.

Response From DRock

alright thanks the problem was I got involved I was looking possibly for a way to save and look what has happenned

dodge intrepid problems....HELP

Showing 2 out of 20 Posts | Show 18 Hidden Posts
Question From badass 87 on dodge intrepid problems....HELP

i have a 2002 dodge intrepid with a 2.7 engine...when i bought the car the engine had blown head gaskets and a bad water pump....it seemed to run fine other than that....we pulled the engine for a rebuild...new chain rods mains valve job water pump guides ......we put the engine back in ....it began to start hard...found bad ground....still starts hard....but the main problem we are having is that when you do get it started and start to drive it runs fine but will not accelerate past 2400 rpm....it acts like it kills the fuel....you let off the gas and go below 2400 all is fine ,,,,runs good...does this all the time....we have replaced the computer....crank sensor .....cam sensor....nuetral safety swith...still nothing seems to help....

please scratch ur heads along with me and collectively maybe we can fix my problem

Response From Hammer Time

I would use a scan tool to see what gear the computer is seeing. If there is a problem with the transmission range sensor and the PCM thinks it is in Park/Neutral, it will engage the rev limiter.

You also want to verify proper fuel pressure.

Response From badass 87

scanner shows proper gear selection...but in park the reverse lights r on?

Response From Hammer Time

scanner shows proper gear selection...but in park the reverse lights r on?

That's conflicting info right there.

Response From badass 87

gear selector and scanner say the gear at same time

Response From Hammer Time

Have you taken the transmission apart?

Response From badass 87

ONLY TO PUT NUETRAL SWITCH IN

Response From Sidom

Is there any codes??? P0016???

Response From badass 87

JUST PUT my ethos snap on scanner on it... codes as follows

po340 camshaft position sensor cicuit A BANK 1 OR SINGLE SENSOR

po344 camshaft position sensor circuit A intermittent bank 1 or single sensor

po 016 crankshaft position- camshaft position correlation bank 1 sensor A


parts we have replaaced.....2 camshaft sensors.....2 crankshaft sensors.....computer and neutral safety switch...


I AM lost

Response From Sidom

You might be out of time....I've seen that P0016 when they have jumped time....

Take a vacuum reading, if it's low & shaky, that not good.......Take a look at the fuel trims and post the data if you can...

Try disconnecting the cmp and see if it will start & run and if that makes a difference.....

Response From Sidom

Try disconnecting the cmp and see if that makes a difference, it may or may not start, some need the cmp others don't.. If you have access to a scope, use 2 channels & scope both the ckp & cmp to see if there are in sync...Also look at the other data I mentioned and post it if you can...

Is there any knocking noise from the timing cover.....The tensioners on those 2.7 can be a little tricky to set if you aren't familiar with them.....

Response From Sidom Top Rated Answer

cmp=camshaft position sensor ckp=crankshaft position sensor

Response From Sidom

Was the the flywheel that came with this engine reused, or was a different one installed????

Response From badass 87

same

Response From badass 87

like i said...this car runs like a top...no sputtering misfires or anythinh
g...sometimesa hard to start..sometimes not...just will not accelerate past 2400rpm....could a bad battery cause this issue?

Response From Sidom

I've suggested, a few times now, to disconnect the cmp and see if that makes a difference.....I was waiting on a reply to what happened when you did this.....I also wanted to know if you had/have access to a scope....

One thing I will mention you can also do (and post back & let us know what you found) since you were having the rev lights coming on at the wrong time, double check all the wiring harnesses to make sure none of them got pinched or damaged when the engine was reinstalled....

Response From badass 87

we have done several of these engines and never had these problems,

Response From badass 87

whats the cmp...to ask a stupid

Response From badass 87

timming has been checked

Response From badass 87

feul pressure has been checked..is good...like i said the safety switch has been changed...

97 dodge intrepid wont start after it overheated?

Showing 2 out of 25 Posts | Show 23 Hidden Posts
Question From cray51065 on 97 dodge intrepid wont start after it overheated?

97 dodge intrepid wont start after it overheated? I have a 1997 Dodge Intreped with a 3.3 litre v-6.... the car overheated and after it cooled down we added some water (water pump was bad) it started back up then dies a few seconds later.. Now after 3 different computers,,,, cam sensor and crank sensor and coil pack it still has no spark... it has compression but has no fire to the plug wires....... did fuel pressure test and has 60 lbs of pressure and a nice steady stream of fuel.. also clean sanded and geased the computer grounds and still has no fire.

Response From Tom Greenleaf

May be hard to do with whatever situation car is in or at but hard computer codes may help if you can get them read,

T

Response From Discretesignals

Did you replace the leaking water pump?
Do you have injector pulse?

Response From cray51065

Not sure if it has injector pulse.. can I use a test light to see?... it has fuel 60lbs and a good stream of fuel.. just no spark... after it overheated it was filled with water and it started and seemed to run fine, closed the hood and it died and has not fired since.. it was towed to a shop and they replaced the computer twice ans was saying they has a 2 band ones.... we are at a loss now.. I have installed a crank and cam sensor and the coil pack.. still no spark

Response From Mr.scotty

Yes you can use a noid light or a 12volt LED or light bulb to test for injector pulse.

Response From Discretesignals Top Rated Answer

Code 12 is a battery disconnect code.
Code 11 means the PCM didn't see the crank reference signal while the engine was cranking.

If you are missing the crank reference signal, you might as well forget about checking injector pulse, because you won't have it.

Unplug the crankshaft position sensor connector and check for voltage and ground in the pins in the connector. Do not use a test lamp to check for voltages on the yellow and dark blue/white wires.

*Yellow wire should have 8 volts with ignition on.

*Black/dark green wire should have 0 ohms and will light a 12 volt test lamp connected to battery positive

*Dark blue/white should have 5 volts with ignition on

Thanks I will check for voltage on those wires and see if my local parts store has a noid light... I was an ase auto tech. but got away from it in 94 and went to diesel and heavy equipment.... cars have changed alot over the years....
Just stumped as why it over heated from bad water pump and after we put water in it and closed the hood it died and has had no spark since then been 6 weeks... shop had it for 5 weeks and kept saying pcm pcm well after 2 new ones it still has no spark.... I replaced coil crank and cam sensors... still no spark

Welp, we can see if the computer is even getting position signals, but you should check those voltages first and the ground first. If you have what you need at the sensor's connector, then you can check for a signal at the computer while cranking the engine. Just have to do some troubleshooting to see what is missing. Seems to me that the repair shop was guessing and playing swaptronics.

Thanks for the info... it may take me a few days to get back to it.. I drive a semi and works some crazy hours so bear with me

Ok I have a black and blue stripe wire that is ground..orange wire has 8.6 volts and blue and black stripe wire has less then 1/2 volt showing on it.....

Response From Discretesignals

Your right. You have an LH body so the colors are going to be what you typed. You seem to have everything you need from the computer to the crank sensor.

Next, your going to have to disable the ignition system, so the car doesn't start. You still need the power from the computer to the crank sensor. To disable the ignition unplug the coil pack.

You'll have to back probe the crank sensor connector at the dark blue/ with light blue stripped wire (5 volt).



You want the connector plugged into the crank sensor and your meter's red lead connected to the back probe. The meter's black lead goes to the negative side of the battery.

The crank sensor is called a hall effect sensor. It is nothing more than a digital switch that opens and closes the 5 volt reference from the computer to ground. As an interrupter passes over the sensor the sensor grounds the 5 volt signal. You meter will show 0 volts when this happens. As an interrupter leaves the sensor the voltage goes back to 5 volts.

If you were to be able to see the on and off signal that is generated by the sensor as the crank shaft is turning it would look like the waveform on the left.



Your digital meter isn't fast enough to watch the voltage change from 0 to 5 V as the engine is running, so the meter is going to average out the voltage to 2.5 volts on a running engine.

Since the engine isn't running, you can bump the starter while watching your meter or you can turn the engine by hand with the ignition on. The meter should show 0 volts when the interrupter passes over the sensor and then back to 5 volts until another interrupter passes. If you see this switching occurring on your meter, then the crankshaft sensor is working and the interupter is interupting..lol.

Ok bumping the starter I got like 3.40 volts as it passes by the flywheel

Response From Discretesignals

You might have to go a little slower and turn the crank by hand while watching the voltage. See if the voltage goes to zero and then back to 5 volts.

Response From cray51065

I had 3.5 volts yesterday and now when I try to roll it around by hand I cant get anything. Im pretty sure the cam sensor is good... you can hear the relay clicking as you roll it over and when you un plug the cam sensor it stops.

Response From Discretesignals

Ok, now you have me confused. Are you checking the cam sensor or the crank sensor? Which relay is clicking. Might be the fuel pump relay because the computer is detecting engine speed.

Response From cray51065

what do I do next?

Response From Discretesignals

Ok,

You were checking the crank sensor signal voltage with your meter and while rotating the engine you noticed a relay clicking. Was the relay clicking the fuel pump relay? If it was, that means that the computer is detecting a crank pulse when you rotated the engine.

Next thing you want to check is the cam sensor signal. The cam sensor works exactly the same as the crank sensor, but it detects when number 1 cylinder is TDC. Unplug the cam sensor connector and check for 8 volts on the orange wire, 5 volts on the tan/yellow wire, and 0 ohms on the black/light blue wire with the ignition on.

Response From cray51065

Well here is a mind blowing event for you.... I went back and rechecked the crank sensor and rolled it very slow by hand and got the 5 volts we are looking for.... so I thought when I did a compression test I only did 4 cyls. So i thought whats it goin to hurt to check them all.... so I take all 6 plugs out and do another compression test and I thought I herd a spark but wasnt sure... After I reinstalled all the spark plugs hooked up all the wires and cranked it it fired right up after 8 weeks of not running....


So how does it overheat and not start for 8 weeks now runs like a champ???
I think its time for 5 gallons of gas and a match

Response From Discretesignals

Hmmm. You have the magic touch?

You should wiggle the harnesses around. especially at the crank sensor, while the engine is running to see if it quits. Could have a wiring issue at or near one of those connectors you might have been moving around.

Response From cray51065

Id say the majic touch... lol.... got the car to die by tugging on the crank sensor wires... so I cut open the insulation around the wires and found some bare wires.... I seperated the bare wires and if you still touch the crank sensor at the plug the car will die.. I think this car is haunted... wiggle crank sensor plug side to side and up car stays running but push down just a little and it dies.... lol
I know the crank sensor wire rens around the back side of the head but where does it go from there?? got dark on me and ran out of time.... im thinkin of goin to local junk yard and getting a harness or just splicing the wires and a good spot and goin from there...

here is what I think happened to the harness to rot the wires.... the crank sensor wires run alon and behind the EGR tube off the manifold and I think that over the years of excessive heat that they just got rotten... so maybe if you ever have this happen again with somebody else it might be a quickk fix.. somehow it just happened that same time water pump went bad and car over heated.

Response From Hammer Time

Check the tension of the contacts inside the plug and bend them with a pick if necessary for a tighter contact on the pin.

Response From Hammer Time

Sounds like he's cycling the key to rotate the engine instead of doing it by hand

Response From cray51065

Ok I had 3.5 volts the other day as I bumped the starter with the coil unhooked.... when you told me to roll it by habd I dont have voltage in the wire you told me to back probe... you can hear the relay clicking in the fuse box... that relay stops clicking when I unplug the cam sensor... so it could very well be the fuel pump relay working...

Response From cray51065

sorry Yes I was checking the crank sensor.. you can hear a relay clicking when you roll it by hand and when you unhook the can sensor it stops.. sorry I was just messing around when I was checking crank senson

Response From cray51065

It had codes 11 and 12 in faults i know one is no distributor reference not sure on the other.. i think so fire when cranking... also have checked and cleaned grounds and swapped out relays to etax. NOTHING im pulling my teeth out here
