Can anybody help me with this code I am getting. It is P0135 and according to my code list it is Heated Oxygen Sensor (HO2S) Heater Circuit Bank 1 Sensor 1. I am also getting U1255 Serial data Line Malfunction. What are they and how do I correct the problem?
Thanks
Bobby
I had the same problem once. Broken wire on the harness side that that heats the O2 to temp. (snipped by a careless mechanic cutting off a tie wrap, no big whoop) Could also be a bad sensor?
