Check engine light (p0141)

dereks2000 · 01-29-2008, 11:08 PM

The check enginge light came on and I took my '02 s2k to autozone and they gave me back the code (p0141) Secondary Heated Oxygen Sensor (Secondary HO2S) (Sensor 2). Can I change that sensor out? or should I go to the dealer or can any mechanic shop do this for me? Anyone who can help me out I appreciate it.

Cool to get the code, and surprise it's not the gas cap for once! If you have a trusted mechanic they should be able to handle it, I don't know if you can do it yourself but it's way probable. I love my Honda service here personally so I just always let them do that kinda thing.

that O2 sensor is easy to get to its on the side of yoy catalytic converter pointing at the tranny

That is the code people get when the put on a test pipe without the O2 bunge adapter I believe. Did you recently put on a TP?

I put an AEM V2 intake on last January. The light only came on a few days ago. Do you think that could have something to do with it. The intake is very close to the ground like a CAI would be. Do I absolutely need the adapter in the future? By the way guys thanks for all of the input it helps out a lot.

No, I don't think the AEM had anything to do with it. Check the O2 sensor and make sure it is attached correctly. You may need to replace the sensor.

where is the bank 1 sensor 2 located? Is this something that I can replace easily?

I believe it is the one sticking out of the cataletic converter as stated up above. It can be replaced, but they are not cheap. You do have to lift the car to get to the plug.
