Possible Causes
NOTE:
- Monitor description. To diagnose a failure on the signal line to the fuel pump driver module
- This DTC is set when the powertrain control module has determined an open circuit through lack of bias voltage, low current flow, no change in the state of an input in response to an output.
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Fuel pump driver module circuit, open circuit, high resistance
