This is from my other post.
21** O2 sensor
25** Open or shorted condition detected in one or more of the idle air control motor circuits
52** Rich air/fuel mixture has been indicated by an abnormally lean correction factor
Can the Oxygen sensor be causing all three codes? I know codes 21 and 52 are O2 related. But isn't code 25 because of air intake. I changed the filter but I am now wondering if I need to just reset the sensor or if I am getting a blockage.
Has anyone put in one of those newer Intake Air Coolers that can be rewashed? Supposedly allows for better air flow and mileage...
I hear that. This would be a good time to get some asbesto gloves that go to the elbow.
Can this be changed from above or does below give me a better chance. I would think below. Autozone has the O2 for $34.99. A little anti-sieze compound, and the O2 tool and the job can be done for under $50 and the dealers want $125 or better to change one.
Of course, the salve for the burns that I will probably get might cost about $80...LOL (hope I didn't jinx myself).
Originally posted by hypnos It doesnt matter which one you do first. Just be careful around those exhuast pipes. Its best to change the sensors after the car has sat for a long time without runing. Those pipes get EXTREMELY hot.
Yea safety wise it would be nice to work on a cold exhaust, but if the o2 sensor is siezed in the port, run the car a bit so the metal can expand a little bit.
also, make sure the wires/connectors aren't too close to (or touching) the exhaust. if you read about some problems i was having with the charging system... it was related to the O2 connector melting and grouding out on the exhaust. it was on the same circuit as the charging system.
