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.

1. Check for open circuit from ignition switch to solenoid.
2. Check engine shutoff solenoid control circuit for open from solenoid to PCM.
