Possible Causes
- The powertrain control module has determined an open circuit via lack of bias voltage, low current flow, no change in the state of an input in response to an output
- Heated oxygen sensor heater circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Control Module Signal Name
- Circuit reference I_A_LSCP Signal
- Circuit reference I_A_LS2 Signal
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Heated oxygen sensor failure
