Oxygen sensor replacement?

Showing 9 out of 14 Posts | Show 5 Hidden Posts
Question From Willybill on Oxygen sensor replacement?

1990, GMC, K1500, 4.3L, 151,000 miles. The oxygen sensor is in the tail of the crossover pipe. When I went to change it the sensor was broke off at the above the nut. I let the truck run to heat up the pipe and I couldn't move the sensor. I then heated the thread area and got it good and red hot still it wouldn't turn. I did this two or three more times until the nipple started to break out of the pipe. The thing I would like to know can I get another nipple to weld in or do I have to get a new crossover pipe? If I take the nipple out I don't think it will be possible to get the sensor out.

Response From Hammer Time Top Rated Answer

Once they are corroded in like that, they get fused to the pipe and then there is no saving it. I'm afraid replacing the pipe is going to be the only savior now. Be sure to put anti seize on the sensor threads to avoid this happening again.

Response From Tom Greenleaf

Generous Motors at its best! We had the audacity to bail them out with borrowed money at that!

T

Response From Hammer Time

Don't blame GM. It happens to all of them. The combination of corrosion and heat just welds the 2 parts together.

Response From chickenhouse

Last I heard, I think they said the lunar rover should still be operable. May have to call in AAA to get it hauled in 4 repair but it's supposed to run- still. I have been pro G M products since the 60's, when it still belonged to G M, and they had design, every year. Not the cookie cutter cars they evolved into. I went to the tech center for many classes, very good training, hands on with newest cars. These days my yard has a diversified collection, albeit still mostly G M, I do/have had many Fords & Chrysler products. Some of the best Fords IMO are still the Model A's. Had many, want another. Basic car- points, condensor, one of the first to employ ignition systems that lasted decades. And how old are YOU??

Response From Tom Greenleaf

USA put a man on the moon in 1969 and can't deal with an o2 sensor! Right. GM designed the lunar landing module the was wire mesh wheeled and it's four wheel drive failed! Nice flicking company! 100 bazillion bucks to do that and their equipment fails!

No sympathy for GM from me!

Response From Loren Champlain Sr

CH; I can't tell you how old Tom G is, but he was involved in the think tank inventing dirt.

Response From chickenhouse

Thinking about it, if T was on the panel to invent dirt, was he standing on water then?

Response From Loren Champlain Sr

Ouch. Not sure you meant it the way it sounded?

Response From chickenhouse

There should be no "ouch" to it, all meant in good humor.

Response From Hammer Time

And Ford and Chrysler have never done anything wrong?

Response From Tom Greenleaf

Hammer and LOL,

">And Ford and Chrysler have never done anything wrong?<"

Of course not! First car was a Mopar in fact,

Tom

Response From Tom Greenleaf

CH "How old are you"

Old enough not to say!

T

Response From Loren Champlain Sr

Agree. Especially if the joker before you didn't use anti-sieze. I've been pretty sucessful using a 3/8 impact. Not strong enough to break it, but the hammering (no pun intended) effect usually works.

Strange - oxy sensor maybe?

Showing 2 out of 11 Posts | Show 9 Hidden Posts
Question From belliott on Strange - oxy sensor maybe?

Just finished a complete exhaust job on my 1993 GMC 3500 with a 350 and AT. Replaced everything from the manifold back including the oxygen sensor before the cat. covt. Now she won't start and is choking black smoke while trying to start! This was only a exhaust job and she ran fine before -- any ideas-- has the new oxy sensor fried my computer??

Response From Tom Greenleaf

That is strange!!

Why did you replace the o2 sensor?

Any chance if you used torches that some wiring got messed up?

Just a thought. Anybody else have ideas here? T

Response From belliott

no flames - just unbolted and dropped the old. Old sensor had welded itself with rust to old pipe so a new one was only $18.

Response From steve01832

Unplug the O2 sensor. With a digital multimeter, set volt scale to 12vdc. Turn key on engine off and test O2 sensor plug on vehicle side. If you have approx. 1/2v the computer is fine. I'm assuming this is a single wire O2 sensor. Computers look only at the O2 sensor voltage after the engine is at operating temp. It shouldn't affect a cold start. My question is "Did you use a welder when you did the exhaust or was it slip on with clamp)? A mig welder can send high voltage back on the vehicle frame and can spike a computer if you leave the battery connected! OOPS

Response From belliott

no it was a slip on with clamps. no electrical charge at all because the battery had been disconnected before I worked on it

Response From steve01832

Can you hear the fuel pump run when you turn the key on? Is it possible the harness got yanked by a pipe or muffler during tear out?

Response From steve01832

Can you smell fuel if you crank the engine for about 20 seconds? If you can, let's check for spark at a plug wire.

Response From belliott

Yes that why this is so puzzling - I took the exhaust off and disconnected the o2 sensor and she still won't start and is choking on black smoke like incomplete burning of fuel.

Response From steve01832 Top Rated Answer

Did you confirm spark?

Response From belliott

Yes, she's trying to start but she can't catch her breath! It's a throttle body injection and the only thing I can think of is the timing is out of sync or the computer is behind or ahead in it firing order???

Response From belliott

Not yet - I'll have to get back to you because I'm away for the truck right now -- I will check the dist cap also maybe it's cracked-- thanks for your time

electronic shift transmission help

Showing 2 out of 14 Posts | Show 12 Hidden Posts
Question From mtgeorge741 on electronic shift transmission help

i have a 1996 gmc jimmy with 4.3l engine and the transmission is an electronic shift transmission. think the 4L60. 123k miles. there is delayed shifting going on. it's acting like it doesn't want to grab the higher gear. there is a slight delay in when putting it into reverse. thinking maybe some sort of sensor on or in the transmission but don't know which one. need help asap

Response From Discretesignals

The wires to the PCS solenoid come into the transmission at the electrical plug you saw on the side of the transmission. The PCS gets power and ground on the light blue/white and red/black wires at the plug.

The electrical harness inside transmission that comes from the other side of the plug that goes to the solenoid itself use a light blue and a purple wire.

Response From Racer 51

I don't know the TSB # (Technical Service Bulletin) but I know there are TSB'S out. Check with a dealer for the TSB'S. Post any error codes that are set so they can be seen.

Response From mtgeorge741

that doesn't help

Response From Discretesignals

How is the fluid level and fluid condition?

Reverse is all mechanical and not computer controlled. If you have a delay going into reverse, there is a pressure problem inside the transmission. You'll have to connect a transmission pressure gauge up and do some line pressure checks.

Response From mtgeorge741

condition is good. level is lower than it was n white smoke from exhaust consistant with tranny fluid burning but dont see any lines as should between the two. i don't see the shift linkage, nothing on the transmission. just a wire going to a large sensor on the side. dont see a kickback, a modulator, nothing. there are no vacuum lines going to the transmission

Response From Discretesignals

The transmission line pressure is controlled by an electrical solenoid called a PCS (pressure control solenoid), so there is no throttle valve cable or vacuum modulator. Can't think of any reason the engine would be burning transmission fluid. Is the white smoke coming out from the end of the exhaust pipe or is it coming from underneath the vehicle?

Response From mtgeorge741

and where is that located? the exhaust pipe

Response From Discretesignals

The end of the exhaust pipe is at the back of vehicle. Unless the muffler fell off...

Response From mtgeorge741

i meant the pcs. i know where the exhaust is.

Response From Discretesignals

The PCS is on the valve body behind the transmission pan. PCS won't cause a loss of fluid though.

Response From mtgeorge741

is there wires going to it? is it grey in color?

Response From mtgeorge741 Top Rated Answer

okay. you'd think that would throw an engine code. when i ran the codes before, nothing showed up about the transmission. just oxygen sensor no circuit, another oxygen sensor code, multiple misfire, cylinder 4 misfire. how do i adjust the shift linkage?

Response From Discretesignals

If the engine has misfires and or problems, you need to correct those first. A bad running engine is going to affect the operation of the transmission. Once you have the engine problem sorted out and you find you still have a problem with the transmission is when you need to take it into a transmission shop and have them take a look at it. They might do some pressure tests and see what line pressure is at when the reverse delay is occurring. It would also be important to find out where the transmission fluid is leaking from.
