DTC P0037, P0038, P0141, P102D; Oxygen Sensor Heater Control Circuit Low (Bank 1 Sensor 2) [11/2013 - 08/2014]: Description
Refer to DTC P0136.
Refer to DESCRIPTION
HINT:
- Sensor 2 refers to the sensor mounted behind the three-way catalytic converter and located far from the engine assembly.
- When any of these DTCs is stored, the ECM enters fail-safe mode. The ECM turns off the heated oxygen sensor heater in fail-safe mode. Fail-safe mode continues until the ignition switch is turned off.
