Check engine light

[Mr Twigbert]

The Aztek's check engine light came on.. Took it to Autozone and had the code pulled -

P0141
Heated Oxygen Sensor - Bank 1 - Sensor 2

Paid $73.00 and got the rear O2 sensor.. Looks like there are 3 total.. 2 up front and 1 in the rear..

Replaced it and drove the car for about 30 minutes today and the light is still on.. Will it turn off or do I have to get it cleared?

Does anyone know for certain that Bank 1 - Sensor 2 is the rear one or did I just piss away $73.00?

well, since it was on an aztek....

I kid, I kid. I have nothing useful to add to this thread

Did you get the codes cleared? it should be the rear 02 sensor for that code.

once you bought the o2's, you should have went back and had them clear the codes or disconnect the battery for like 15 min.

[Mr Twigbert]

I thought the code would clear it self after putting in the new part and driving it for a bit..

[wrencher]

It should self clear if that was indeed the problem. It just will take a few drive cycles to get it to go out on it's own.

[wrath]

It'll clear after about 20 minutes of closed-loop driving if the problem is gone.

Pull the PCM A and possible B fuses, instant light reset. And for the newbs its if its hard code it will take probably 2 or more driving cycles with to check its function and turn the light off on its own if there is no more issues reported. It took 2 errors to make it happen in the first place, which could have took place over a period of time.

what he said^^ not all codes go away right away some take some time to clear out but as tom said reset it your self

Where ever you bought it from probably wont clear it for you, people were clearing codes and going through emissions, Ive still got that scanner so I could clear it for you, but chances are it will clear itself before you'd even get here

IMO i wuldnt take a check engine light to auto zone. everytime a car comes to my shop they have a printout of several cars on it and it is ALWAYS something with an oxygen sensor. id say take it to a shop and if its like my shop we will scan into it for a code and we dont charge for a scan test unless you have the work done.

Conditions for Clearing the MIL/DTC

• The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.

• A current DTC, Last Test Failed, clears when the diagnostic runs and passes.

• A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.

• Clear the MIL and the DTC with a scan tool.

[Reverend Cooper]

^ he is absolutely correct,a history code will fail emissions still. clearing witha scan tool is the best bet

A drive cycle should never take more than 10-15 minutes. Check this out, it helped me get my EVAP readiness monitor to go, so I could pass their fruity little test, even though I'm confident my V8 is cleaner than 90% of the others out there with my AFRs dead nuts.
