Default 99 SW2, re-ocurring p0414 O2 sensor Code

Hey,

I need to pass emissions check. My check engine light has been one for a while because of the O2 heater circuit malfunction code.

I put in a new cat, and bought a new O2 sensor (Bosch direct fit plug) and the code ended up coming back, but not the light (yet). I know the code has to occur twice to throw the CEL, but the fact that there is 1 occurence in the computer is bugging me. Weird thing is it keeps coming back, but just the one. If I try to clear it while it's running it will erase it and then say 1 code remaining (the one I just erased). If I erase it while it's NOT running it will get rid of it all together, but then come back within 1 or 2 minutes of starting back up.

I dont understand how it is ALWAYS occuring just once, but after multiple starts and ignition cycles it wont occur a second time to throw the CEL.

Anything on this?

Thanks,
-Oliver

DTC P0414 Secondary Air Injection System Switching Valve A Circuit Shorted

Are you certain that your P0414 error code is what you saw displayed and attempting a correction but to the wrong parts? The above OBD II DTC is from our How-to ibrary and we here at Saturnfans tend to compare DTC's against references that are as accurate as posted by trusted members and not from Googling that can mislead with misinformation sometimes.

Ok, that's better. This is for the rear O2 sensor with a heater circuit problem.
