How to Test O2 Sensors on '97?
I have a '97 Explorer, Control Trac, auto trans, and 4.0L OHV engine. I
have error codes PO136 and PO141. I tried to test the O2 sensors as outlined in my Hayne's manual but am unable to manage to get a wire into the connector so I can test it. Is there a trick to this? Hayne's says not to backprobe the sensor itself. Am I going to destroy it if I stick a pin in the wire? Any other common problems that might cause these error codes besides the O2 sensors? |

Absolutely will. > Any other common problems that might cause these error codes >besides the O2 sensors? > Common? Might be, (I'm not an expert on this engine) but the first thing is to check the connector make sure it is absolutely clean inside, and tight. Then test the sensor if you can, or replace it if you are unable to test. I've found this to resolve many O2 sensor problems. |

Man... you have busted my chops in the past... Payback is a real bitch,
ain't it.... You thought I was a stupid dink..... in fact, I ain't stupid... but I am a dink..... Let us know what you find.....

Well gee, as I recall it all started when you called me Goofy. It turns out that Goofy is my brother and just happens to look a lot like me. From my point of view you have a tendency to ridicule people who ask legitimate questions here but since you are so much smarter than everyone else you think they are dumb questions. > > You thought I was a stupid dink..... in fact, I ain't stupid... but I am a > dink..... > I never said or even thought that you were stupid.

How to Test O2 Sensors on '97?
Actually, most of it comes from some dork insisting that beating on an oil
pan was a "professional" fix. I do not recall if it was you or if you were just a supporting actor.... None-the-less.... the general trend was to aver that dealer techs are overpriced idiots and true mechanics used hammers more than any other tool - including their brains... 'Nuff said.... P0136 (as in Pzero136) is an indication that there is a problem with the sensor reading - the O2 content indication is outside of programmed expectations... Bank one sensor two, if you are paying attention and, you might notice, that this is the ONLY downstream sensor... P0141 (as in Pzero141) is an indication the there is a concern with the HEATER circuit on this SAME O2 sensor... Two DIFFERENT circuits on ONE component are faulty..... It isn't time to test O2 sensors, it is time to start checking wiring... a least for us overpriced dealership idiots.... Could be that someone has been working around the transefer case and might have displaced the wiring... allowing it to melt to the exhaust system....

Some dork was insisting that a "professional" fix meant only replacing the S-10's settling engine mounts, even when that maintained the original design deficiency. > just a supporting actor.... None-the-less.... the general trend was to aver > that dealer techs are overpriced idiots and true mechanics used hammers more > than any other tool - including their brains... Thinking mechanics will use a hammer when it makes sense. Putting needed clearance in an oil pan with a ball-peen hammer is an example of using one's own brain to solve a problem. > 'Nuff said.... There's more... Some dork then went on his typical wild exaggeration spree, telling the next poster to go ahead and wail on his axle with a sledgehammer to repair it. |

I'm pretty sure I never called you an overpriced idiot or any such thing, I probably said that I am not willing to pay $4000 to repair a truck that is worth $2000 and decided to do the repairs myself. Either that or junk it. I recently replaced the rear seal on the transfer case but I've checked the wires to the O2 sensor since then and didn't see anything wrong but I'll check some more. > > "Ulysses" > wrote in message > ... > > > > "Jim Warman" > wrote in message > > news:Xb2Wl.29458$Db2.1729@edtnps83... > >> Man... you have busted my chops in the past...
