What it means

P0215 is the generic code for a fault in the engine shutoff solenoid circuit. This solenoid is mainly found on diesel engines, where it cuts the fuel supply to stop the engine when the ignition is switched off. The control unit sets the code when it sees a voltage, current or feedback signal from the solenoid circuit that does not match what it commanded.

Symptoms

Engine continues to run on or is slow to stop after switching off the ignition
Engine cranks but will not start, or starts and then stalls
Engine cuts out unexpectedly while running
Engine management warning light on
Hard starting or intermittent no-start

Possible causes

Faulty engine shutoff solenoid (stuck, sticking or open or shorted coil)likely
Damaged wiring, chafed loom or corroded connector at the solenoidlikely
Low supply voltage or poor earth to the solenoid circuitpossible
Blown fuse or faulty relay feeding the solenoid circuitpossible
Fuel contamination or debris causing the solenoid or its valve to stickpossible
Fault in the engine control unit driver circuitrare

How to diagnose

Read all stored codes and freeze frame data, and note whether the fault is constant or intermittent
Check the battery condition and charging voltage, as low voltage can upset solenoid circuits
Visually inspect the solenoid, its connector and the wiring for damage, oil contamination, heat damage or corrosion
Check the relevant fuse and relay against the vehicle wiring diagram
Check for supply voltage and a good earth at the solenoid connector with the ignition on, and while cranking
Measure the solenoid coil resistance and compare with the manufacturer specification, as values vary by model and engine
Listen for or feel the solenoid operating when the ignition is switched on and off
Check the control unit command signal using the wiring diagram, and only suspect the control unit once wiring and solenoid are proven good

How to fix

Replace the engine shutoff solenoid if it is faulty or stuck
Repair or replace damaged wiring and clean or replace corroded connectors
Restore correct supply voltage and earth connections, and charge or replace a weak battery
Replace the blown fuse or faulty relay after finding why it failed
Clean or repair the fuel system if contamination is affecting the solenoid, following the manufacturer procedure
Repair or replace the control unit only if testing confirms a driver fault

Can I keep driving?

Medium severity

The car may be driven if it starts and runs normally, but get it checked soon as it could fail to start or stall without warning. Avoid driving if it stalls, will not shut off or runs erratically.
