I took my 2000 galant to auto zone to find out why my service engine soon light won't go off, and they testing and said it was a sensory problem and said when I take it to an auto repair tell them it was a P0135.
Trouble code P0135 means: HO2S Heater Performance Sensor 1
O2 Sensor malfunction, Bank 1, Sensor 1
O2 sensor Heater Bank 1 Sensor 1
This is a generic O2 Sensor code, usually used on right bank
The P0135 code indicates a problem with the oxygen sensor heater circuit in the upstream oxygen sensor. While this issue alone does not directly cause multiple misfires, it can lead to improper air-fuel mixture readings, which may result in poor engine performance and potentially contribute to misfires over time. If the engine is running poorly due to an incorrect air-fuel mixture, it might trigger multiple misfire codes. Therefore, addressing the P0135 issue is important for overall engine health.
Code P0135 means: Front HO2S Heater circuit Fault (Sensor 1)
it is the ignition coil is the problem replace it p0135 for Volvo not sure about p1081
