I took my Magnum to be smogged and the check engine light came on while driving there. I figured I'd have them give me the code/problem. Failed smog.., P0038 error code saying "Ho2S Heater Control Circuit High (Bank 1 Sensor 2). I changed the 02 sensor on the driver's side after the cat. I reset the check engine light (disconnecting the neg battery terminal) and drove for about 10 minutes but light came back on. Is there something else that I'm missing????
