P0215 indicates a malfunction in the engine shutoff solenoid circuit. This solenoid controls fuel delivery to stop the engine when the ignition is turned off, and is most common on diesel applications. The code sets when the control module detects an open, short, or unexpected voltage condition in the solenoid control circuit.
The solenoid internal coil opens, shorts, or mechanically binds, preventing proper operation.
Chafed, broken, or corroded wires between the PCM and solenoid create open or short circuits.
Spread, corroded, or contaminated terminals at the solenoid or PCM connector increase resistance or cause intermittent contact.
A blown supply fuse or stuck relay prevents voltage from reaching the solenoid circuit.
Internal driver transistor failure in the control module is possible but uncommon; verify circuit integrity before suspecting the PCM.
Rarely. The vast majority of P0215 codes are caused by the solenoid itself, wiring, or connectors. The PCM should only be considered after all circuit tests pass and the solenoid is confirmed functional.
If the engine shuts off normally, the vehicle may be drivable, but a sticking solenoid can cause a no-start or failure to shut off. Diagnose promptly to avoid being stranded.
Primarily yes. The code applies to engines with an electrically controlled fuel shutoff solenoid, which is standard on most diesel platforms and some older gasoline systems.
The shutoff solenoid is not receiving the command or lacks power to move the fuel cutoff plunger, so fuel continues to flow. This is the classic symptom of a P0215 fault.
