Need Help...... Getting Code
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?

I just got this code today !!!!!!!
I did a some very hard canyon driving. Then I made two stops. When leaving the second stop the CEL came on with the P0135 code.
The link above says it trips the code when 2 consecutive codes starts with incorrect voltage is detected.
Recently had 402 engine installed so everything was apart. This was the first good workout (engine has about 1K miles on it)
Wonder if it will be wire or sensor......
