P0215 — Engine Shutoff Solenoid Circuit Malfunction
What P0215 means
P0215 is set when the engine control module detects a problem in the engine shutoff solenoid circuit. This solenoid opens the fuel supply when the ignition is on and cuts it off when the key is turned off. It is most common on diesel engines, where it sits on the injection pump. When the circuit signal or voltage is out of range, the engine may fail to start, stall, or keep running after shutdown.
Symptoms
- Check Engine light is on
- Engine cranks but does not start
- Engine stalls unexpectedly while driving
- Rough idle and reduced power
- Intermittent fuel delivery or hesitation
- Engine does not shut off right away with the key off
Possible causes
- Failed engine shutoff (fuel cutoff) solenoid
- Damaged wiring or corroded, loose connector
- Blown fuse or bad relay in the solenoid circuit
- PCM/ECM output driver or software fault
- Mechanical sticking in the shutoff linkage (uncommon)
How to diagnose
- Scan all codes and freeze frame data and note any other fuel or power supply codes
- Inspect the solenoid connector and harness for chafing, corrosion, oil or fuel contamination
- Check the fuse and relay for the solenoid circuit and swap in known good parts if needed
- Measure supply voltage at the solenoid connector with the ignition on, and check wire continuity to the PCM and ground
- Test the solenoid coil resistance against the manufacturer's spec
- Apply power directly to the solenoid and confirm it clicks and the plunger moves freely
- If wiring and solenoid are good, check the PCM control signal and look for software updates
Common fixes
- Replace the engine shutoff solenoid
- Repair damaged wiring and clean or replace connectors
- Replace the faulty relay or fuse
- Reprogram or replace the PCM if it is confirmed faulty
Questions and answers
What does code P0215 mean?
The PCM found a fault in the circuit of the solenoid that cuts fuel to stop the engine. As a result the engine may not start, may stall, or may not shut off.
Can I drive with P0215?
It is best not to. The engine can stall suddenly, and without it running you lose power assist for steering and brakes. Only drive a short distance to a shop.
What should I check first for P0215?
Start with the fuse, relay, connector and wiring to the solenoid. These are the most common and cheapest causes and are quick to check.
This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
