P0215 – OBD-II Trouble Code Technical Description

Engine shutdown solenoid malfunction

What does trouble code P0215 mean?

Code P0215 indicates a faulty solenoid or crankshaft position sensor.

This diagnostic code applies to vehicles with OBD-II and an engine cut-off solenoid. This may include brands such as Lexus, Peugeot, Citroen, VW, Toyota, Audi, Dodge, Ram, Mercedes Benz, GMC, Chevrolet and others. P0215 means the powertrain control module (PCM) has detected a problem with the engine cut-off solenoid.

The engine cut-off solenoid typically prevents fuel from flowing to the engine in certain situations such as a collision, overheating, or loss of oil pressure. It is commonly used in diesel engines and is located in the fuel supply system.

The PCM uses data from various sensors to determine when to cut off the fuel and activates the solenoid. If the PCM detects an anomaly in the solenoid circuit voltage, it may trigger the P0215 code and illuminate the Malfunction Indicator Light (MIL).

What are the symptoms of the P0215 code?

Symptoms associated with a P0215 code include a check engine light and, if the crankshaft position sensor is faulty, possible engine starting problems.

Because the conditions that cause the P0215 code can also cause the engine to fail to start, these symptoms should be considered serious. Possible symptoms of a P0215 code include:

If a P0215 code is stored, there may be no symptoms.
Difficulty or inability to start the engine.
Possible appearance of other codes related to the fuel system.
Possible signs of ineffective exhaust.

These symptoms may indicate a problem that requires immediate attention and diagnosis.

Possible reasons

Possible reasons for the P0215 code may include:

Faulty engine cut-off solenoid.
Faulty engine stop relay.
Faulty tilt angle indicator (if equipped).
Open or short circuit in the engine shutdown system.
Bad oil pressure transmission unit.
Faulty engine temperature sensor.
Faulty PCM or PCM programming error.
Faulty crankshaft position sensor.
Faulty ignition switch or lock cylinder.
Damaged wiring in the engine stop solenoid circuit.
Faulty powertrain control module.

How to diagnose code P0215?

If the vehicle in question has been involved in an accident or the vehicle's angle was excessive, clearing the code may be enough to clear the problem.

To diagnose code P0215, the following sequence of actions is recommended:

Use a diagnostic scan tool, digital volt-ohm meter (DVOM) and a reliable source of vehicle information.
If there are engine oil pressure or engine overheat codes, diagnose and repair them before addressing the P0215 code.
Please note that some specialized vehicles may use a lean angle indicator. If applicable, resolve all related codes before addressing the P0215 code.
Connect a diagnostic scanner and get stored codes and freeze frame data.
Clear the codes and test drive the vehicle to see if the code has cleared. If the code resets, the problem may be intermittent.
If the code does not clear and the PCM goes into standby mode, there is nothing left to diagnose.
If the code does not clear before the PCM goes into ready mode, use the DVOM to test the engine cut-off solenoid.
If the solenoid does not meet manufacturer specifications, replace it.
Check voltage and ground at the solenoid connector and PCM.
If there are no voltage and ground signals at the PCM connector, suspect a faulty PCM or a PCM programming error.
If any of the signals are detected at the PCM connector but not at the solenoid connector, check the relay and circuit.
If there are no problems with the solenoid, check the crankshaft position sensor.
Check the ignition switch and lock cylinder and replace them if necessary.
If no problems are found, check the transmission control module using the OBD-II scan tool.

Diagnostic errors

It is important to avoid common mistakes when diagnosing a P0215 code, such as pre-replacing the crankshaft position sensor, ignition switch or engine shutdown solenoid before thoroughly checking and following the manufacturer's recommendations. It is always best to follow the manufacturer's recommendations and guidelines for an accurate and reliable diagnosis.
