Possible Causes
NOTE:
- Monitor description. Open circuit detected by the ignition control module, passed to main CPU within powertrain control module and sets the DTC.
- This DTC is set when 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.
- Ignition coil connector is disconnected, connector pin is backed out, connector pin corrosion
- Ignition coil fuse supply failure
- Ignition coil circuit open circuit
