Mass Air Flow sensor?

Showing 3 out of 3 Posts
Question From ford91486 on Mass Air Flow sensor?

Just a general question here. My mechanic did some engine work for me. Now it is idleing like crap and I am having problems with my fuel delivery. It is running really rich and my emissions are real high according to my inspection that just failed. I tried to locate my Mass Air Flow sensor to clean it. I cant find it. I called my mechanic up and asked him where it was. He said it does not have one. Is it possible for my Truck to not have a MAF.

It is a 1992 Ford F150. With a 1995 302 V8 5.0L.


Thanx for all your help.

Response From way2old

If it is a 92, it will not have a MAF. It probably has a MAP sensor. Click here for some information.

Response From ford91486 Top Rated Answer

Ok That makes perfect sence. I am replacing the MAP. I wasnt sure if I should have both the MAP and MAF.

Question From tommyp on Help with a mustang

Need some help guys... 1995 ford mustang gt with a 5.0... When the engine is cold .. It will not take throttle, pops back threw the intake.. Doesn't have the problem when engine is warm.. Have replaced tps sensor, and done complete tune up... Any ideas on what else to look into??

Response From Hammer Time Top Rated Answer

They had a lot of problems with the Mass Air Flow sensors in those.
See if it runs better with it unplugged.

Response From tommyp

Thanks guys I will check those out.. It has 180,000 on it.. Nothing has been done to the engine that I know of.. Have had it for about a year and this just started to happening in the last month

Response From Tom Greenleaf

Anything to do with vacuum leaks anywhere and intake air flow integrity. Age and miles there is a lot possible as said. Put some PB on the black plate that says 5.0 now - torx screw now just in the case the upper intake needs to come off there are two bolts under that plate.

One more thing for later if things check out is on my list but not usually a cold only thing,

T

Response From Tom Greenleaf

See if you can get codes. May or may not help for 1995?

Cold only so see if the Coolant temp sensor (tells it that it's cold and add gas like choke. Connection or you can test ohms of the thing. Other things possible too. How many miles on this thing? Anything messed with on engine that you know of?

2002 Ford Focus Idle problem

Question From Tk27 on 2002 Ford Focus Idle problem

2002 Ford Focus SOHC
My daughters car started a couple of weeks ago, when the car warms up its hard to get accelation at a stop and idle rough. It smooth out some once you get moving.
Replaced catalytic converter $658.00 California emissions , fuel pump and still didnt help. No codes have ever come up in the computer. Took to a mechanic thats the best in town diagnosing hard to fine problems. He has given up and said must be in the computer even though he gets no codes. He replaced the fuel pump and module (Ford Part) and it didnt help, he checked exhaust , mass air flow sensors, and so on. He said its ok until the car warms up. He a great mechanic and he worked on it for a week trying to find the problem. Any ideals would be appreciated. Thanks

Response From Hammer Time

What part of don't post to this old thread didn't you understand?

Response From zx5user

Just fixed my idle problem by replacing the overdrive solenoid. It gave all the symptoms of fueling problems before
the solenoid actually failed and gave out a failure code. I took it to the dealer twice and an Indepedent shop once,
all said everything was fine with the fueling/emissions system, no error codes.

My mechanic has a theory - he thinks the Overdrive solenoid starts to fail before it will give an error code.
During the failure it will keep the torque converter locked up at times when it should not be. This puts
a strain on the engine that reduces its ability to keep a normal idle and even causes the car not to idle,
but you can rev it up and keep in going. It is intermittant which is the problem.

This solenoid is a common failure part, it is very small and is probably an systemic engineering flaw
in an automatic Focus from your era. Chevy had the similar problem part. You will see many complaints and problems
with this part and the electric window regulators on this model. The selonoid will fail again.

While that was indeed good to know, this thread is a year old. I'm sure the poster has taken care of it. Please read the forum rules at the top of the catergory. When you post to an old thread like this everyone who has ever posted to it gets an email notification and for us who are mods here the inbox gets full fast. For the people who made the thread it gets annoying. Please look at dates prior to posting a reply from now on.

Response From Discretesignals

Does it feel like it is misfiring? Did you mechanic use a high end scan tool to look at mode$06 info to see if there are any misfires going on in TID $53? If it is misfiring, it may have not reached the threshold for creating a trouble code yet. What are the long and short term fuel trims reading when the problem is occurring?


Here is an interesting TSB that may relate:

FORD:1997-2002 ESCORT2000-2002 FOCUS MERCURY: 1997-1999 TRACER

This article supersedes TSB 02-09-01 to update the service and part information.

ISSUE
Some vehicles equipped with the 2.0L SPI engine may exhibit a malfunction indicator lamp (MIL) illuminated and diagnostic trouble codes (DTCs) P0300 through P0304 stored in memory. The vehicle may also have a rough idle or reduced power condition, and/or may stall at an idle. This may be caused by sticking exhaust valves due to excessive carbon build-up.

ACTION

Check for faulty fuel injectors and ignition wires. One or more exhaust valves may be temporarily sticking due to carbon build-up between the valve stem and guide. If the diagnostic checks point to a sticking exhaust valve, the cylinder head assembly may need to be replaced with a new level cylinder head assembly with revised valve guides, revised exhaust valves will also need to be installed to help prevent carbon build-up. Refer to the following Service Procedure for details.

SERVICE PROCEDURE
NOTE THIS PROCEDURE APPLIES ONLY TO THE 2.0L SPI ENGINE.This condition usually results in misfire when the engine returns to idle after running approximately 2000 RPM or higher.

1. Use the worldwide diagnostic system (WDS) to test for Power Balance with the engine at idle. Check for cylinder misfire. If misfire is occurring constantly, go to Step 3.

If misfire is not occurring, attempt to induce misfire by performing the following step:
a. Apply the parking brake and keep the transmission in Park or Neutral. Bring the engine to approximately 2800 RPM and hold for one (1) minute. Check the WDS Power Balance display while holding engine speed constant. Allow the engine to return to idle and watch the WDS Power Balance display for a misfiring cylinder.

2. If WDS Power Balance indicates a misfiring cylinder with the previous test, one or more exhaust valves may be intermittently sticking due to carbon build-up between the valve stem and guide. Replace the cylinder head with the new level cylinder head with revised valve guides. Once stock is exhausted of the loaded cylinder heads, the cylinder head will come bare so revised exhaust valves will need to be installed in place of the original valves. The revised valve guides and exhaust valves help prevent carbon build-up.

Consult the appropriate model year Workshop Manual for removal and installation procedures for the Cylinder Head Assembly.

3. If WDS Power Balance did not indicate a misfiring cylinder with the previous test or a misfire is occurring constantly, the misfire may not be due to a sticking exhaust valve. Refer to the appropriate model year Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual for further diagnosis. Other possible causes may be, worn or arcing ignition wires, base engine compression, fuel injectors, fuel injector harness resistance or PCM injector driver signal. Perform diagnosis and repair as necessary.

4. After completing either Step 2 or Step 3, replace the PCV Valve (YS4Z-6A666-AC) (Motorcraft EV-244) on model year 2000-2002 Focus or 2000-2002 Escort. Vacuum fluctuations from engine misfire may prematurely wear the PCV valve on those applications.NOTE THE CYLINDER HEAD ASSEMBLIES LISTED BELOW WILL BE BARE CASTINGS ONCE SUPPLY OF LOADED HEADS IS EXHAUSTED, IN MOST CASES IT WILL BE NECESSARY TO REPLACE ONLY THE PARTS LISTED BELOW, ALL OTHER PARTS CAN BE REUSED.

Does it feel like it is misfiring? Did you mechanic use a high end scan tool to look at mode$06 info to see if there are any misfires going on in TID $53? If it is misfiring, it may have not reached the threshold for creating a trouble code yet. What are the long and short term fuel trims reading when the problem is occurring?

It has misfired... Thank you for the information , i was just trying to get better informed before i go to the dealer..The catalytic converter was deferentially bad, he showed it to me, I dont know if that helps.

Response From zmame

I would take coil pack off an inspect it for cracks. Also check spark wire terminal for signs of carbon or rust.. These cars are famous for engine mounts too they shake alot when idle in gear stopped.

Also check actual fuel pressure and with scanner and make sure they match.. The pump voltage is controlled by the fuel pump module and fuel rail pressure sensor to regulate pressure.. if the pressure sensor is not reading properly it will cause low or high fuel pressures.

In some 2.0L SPI SOHC have been knowen to fracture or drop valve seats causing low compression on a cylinder(usally #4 cylinder). This can be checked with a compression test.

Check fuel trims with scanner make sure they are within + or - 5% on short and long.

Also if the old converter came apart there is a chance that a part of it is still stuck in the exhaust somewhere and plugging the exhaust periodically. This can be checked with back pressure gauge or you can use a vacumm gauge to check for backpressure..

EGR could be partially stuck open.

Response From Sidom

You didn't happen to wash the engine as well did you?

That sounds a lot like a bad Mass Air Flow sensor. They had a bad batch of those on the Mustangs.

Question From terry.justice on 2006 2.3L FORD ESCAPE WILL NOT REB UP

REPLACED MOTOR WITH A 2005 2.3L OUT OF A FORD FOCUS. STARTED MOTOR, IDLES ROUGH AND WHEN I PRESS ON GAS PEDAL IT WILL NOT EXCELLERATE.

Response From Sidom

I guess we should start off with what codes this thing is throwing...

Response From terry.justice

ANY SUGGESTIONS GUYS?

Response From chickenhouse

Put a gauge on the fuel pump pressure?

Response From terry.justice

It turns out that the harmonic balancer is different on a 2005. I switched the balancer that was on the 2006 and it runs fine. Who would have thought it.

Response From Hammer Time

Certainly not us since you never even mentioned replacing a balancer, never mind the wrong year.

Response From terry.justice

The balancer was on the 05 when I got it it had'nt been taking off I assumed it was in time. That's the only reason I did not change it and also the block and head is the same on a 2005 and 2006.

Hooked computer to it one code came up EGR Valve.
Started vehicle there was about four codes that came up EGR Valve, Throttle position Sensor, Idle Air Control Valve and the Mass Air Flow Sensor. He cleared out codes. There were no other codes that came up. When we hooked up computer and started it the first time it revved up a couple of times and went back the way it was.
