knagel Posted February 8, 2009 Report Share Posted February 8, 2009 Recently had "check engine" light come on with the following associated codes: P0139 - Heated O2 Sensor Slow Response Bank 1, Sensor 2 P0135 - Heated O2 Sensor Heater Performance Bank 1, Sensor 1 P0141 - Heated O2 Sensor Heater Performance Bank 1, Sensor 2 Any diagnosis of the specific problem, a heater?, an O2 Sensor?, loose wires?, other? How should I diagnose, what parts do I need, how difficult to repair? Thanks in advance for your responses. Ken Link to comment Share on other sites More sharing options...
