| Post subject: | P0038 sensor code |
My 04 had this code come off and on for several months but runs great! I have 140.000 miles on her but runs like new. I have replaced the bad sensor, new plugs , new PCV valve and corrected some vaccume leaks but still getting the same code any suggestions? |

p0038 code, bank 1 sensor 2, second sensor on the left. Did you replace it with a factroy sensor ? That sensor usually has a large zip tie holding the wiring harness down and will pinch the harness in some case's. Might check or straighten out the wiring and clear the code, see if that makes a diff. |

Bad Idea !! I have installed a lot of o2's in my line of work and the aftermarket o2's arn't always sending the feedback that the PCM want's or like's ! I just replaced that o2 on my KJ and it was around $50.00, get a mopar o2 !! |

I just replaced that o2 on my KJ and it was around $50.00, get a mopar o2 !! P0038 is B1S2 high circuit voltage,does not mean in anyway the O2 sensor is bad,wiring could be bad or the cat could be bad and so on and so on. |

I have bought Bosh o2s for my xj from advance auto, and other vehicle that I have worked on in the past, and have had some problem's with the light coming back on or never going out !! I have then bought factoy GM or Chrysler o2s and the light either went out or never came back on !! Not sure if the factoy o2s were bosh or not ! The p0038 codes that I have seen are heater circuit codes and are 99 percent of the time a o2 prob !! |
