Question about 2006 Dodge Magnum
2005 Dodge Magnum 2.7 came up with 0038 error code. I took it to have it smogged and the result was a failed test and the details read HO2S Heater control circuit high (bank 1 sensor 2). I changed out the O2 sensor on the driver's side after the cat (figuring that the driver's side would be bank 1). I reset the code (disconnecting the batteries neg terminal) and drove for about 10 minutes the check engine light came back on with the same error code. Should I change out the other 02 sensor or is there another way to reset the code??????
Your heated O2 sensor has a heeater problem most likely. Most likely time to change out your HO2 sensor. Most cars actually have only primary heated. Not sure for this application but would thus assume the primary sensor or otherwise known as precat O2.
With a sensor high you have high voltage back to the pcm thus most likely shorted heating element.
There is an outside chance of a cross short to the ground circuit of your O2 sensor. If after replacing your sensor you still have a problem then start looking for this.
I see you went to the auto parts store and got an HO2 sensor (Should be a 22mm or 7/8" -- same size) and replace the Primary and if that do not solve the problem, then see if you have a heated postcat HO2 if not then see above.
Good luck and hope this helps, oh and Bank 1 is where your #1 cylinder is.
