DTC 13, Engine Shutoff Solenoid Circuit Fault: Notes
When ignition switch is in OFF position, engine shutoff solenoid is in NO FUEL position. By providing a ground path, PCM energizes solenoid which then allows fuel to pass into fuel pump. DTC 13 will set when:
- Ignition voltage is present on engine shutoff solenoid control circuit when PCM is requesting engine shutoff solenoid on.
Or
- No ignition voltage is present on engine shutoff solenoid control circuit when PCM is has requested engine shutoff solenoid off.
PCM will default to a current and history DTC 13 will be stored.
- Check for open circuit from ignition switch to solenoid.
- Check engine shutoff solenoid control circuit for open from solenoid to PCM.
