Engine Shutoff Solenoid Malfunction

What does that mean?

This generic powertrain diagnostic trouble code (DTC) typically applies to OBD-II equipped vehicles that have a shutoff solenoid. Makes of vehicles may include but are not limited to Lexus, Peugeot, Citroen, VW, Toyota, Audi, Dodge, Ram, Mercedes Benz, GMC, Chevrolet, etc.

When your OBD-II equipped vehicle exhibits a code P0215, it means that the powertrain control module (PCM) has detected a malfunction in the shutoff solenoid for the engine.

Most commonly, the engine shutoff solenoid interferes with the fuel supply to the engine under certain specific circumstances. These circumstances may include (but are not limited to) a vehicle collision, vehicle roll-over, extreme engine overheating, or extreme loss of oil pressure to the engine. The engine shutoff solenoid system is most frequently utilized in diesel powered vehicles but not exclusively.

Typically, the engine shutoff solenoid is positioned in the fuel delivery system. It consists of an electronically controlled solenoid (which operates a valve type actuator), and some method for rerouting fuel back to the storage tank when the engine shutoff solenoid is activated. The PCM uses inputs from various engine and body position sensors to determine when fuel shutoff is required. When this occurs, the PCM provides a voltage signal to the engine cutoff relay (which forwards it to the solenoid) and the solenoid is activated. Once it is activated, the valve prevents fuel from reaching the engine and diverts it back to the fuel storage tank via a specially designed low pressure return line.

The PCM constantly monitors engine shutoff solenoid circuit resistance (and the resultant changes in voltage), when the ignition switch is in the ON position. If the PCM detects a level of voltage from the engine shutoff solenoid circuit that varies from what has been programmed, a code P0215 will be stored and a malfunction indicator lamp (MIL) may be illuminated. In some vehicles multiple failure cycles will be necessary for MIL illumination.

Code Severity & Symptoms

Since the conditions which contribute to a stored code P0215 may also result in a no-start condition, it should be classified as severe.

Diagnostic and Repair Procedures

I would like to have access to a diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source before attempting to diagnose a code P0215.

If there are engine oil pressure or engine over temperature codes present, diagnose and repair those before tackling this one. Certain specialty (usually with a focus on off-roading) vehicles utilize a vehicle tilt angle indicator in the engine shutoff system, if this is applicable to the vehicle in question, rectify any codes that are pertinent before addressing the P0215 as well.

Engine shutoff systems are very diverse. Many different input signals are used by the PCM to determine whether engine shutoff is warranted. One automaker may use the level of oil pressure and another may use vehicle tilt angle. Consult your vehicle information source for the specifics of the engine shutoff system in question.

Connect the scanner to the diagnostic port of the vehicle and retrieve al stored codes and freeze frame data. Make a record of this information as it will likely be helpful as your diagnosis proceeds. Now, clear the codes and test-drive the vehicle to see if the code is reset.
