Code P0215: engine shutoff solenoid: fault
P0215 means: engine shutoff solenoid: malfunction.[1][2] The ECU monitors the electrical circuit of the solenoid that cuts fuel delivery to the engine. If the voltage or resistance it measures is not as expected, it stores P0215 and may turn on the engine warning light. This system is used mainly on diesel engines, though not only on them.[1]
What code P0215 means
The ECU monitors the electrical circuit of the solenoid that cuts fuel delivery to the engine. If the voltage or resistance it measures is not as expected, it stores P0215 and may turn on the engine warning light. This system is used mainly on diesel engines, though not only on them.[1]
In some vehicles the ECU triggers the cut-off after a collision, a rollover, extreme overheating or a serious loss of oil pressure. That is why the specific system, part and relay depend on each manufacturer.[1]
It is a generic code (P0), but CarWiki describes it as a fault in the electrical engine shutoff circuit linked to the main relay or the ECU, so the diagnosis varies by car.[2]
Original definition (SAE J2012): Engine Shutoff Solenoid Malfunction[1][2]
Causes of P0215
From most to least likely, according to the sources.
Symptoms
- Engine warning light on, although in some cases there are several fault cycles before it comes on.[1][2]Engine warning light: faults that cause it
- Difficulty starting or an engine that will not start.[1][2]Hard to start: faults that cause it
- Uneven running and engine jerking.[2]Jerking: faults that cause it
- Loss of power.[2]Less power: faults that cause it
How to diagnose P0215
In order: from the most likely and cheapest to check to the most expensive.
- 1Read all codes and the freeze-frame data with a diagnostic tool, and first repair any oil pressure or engine temperature codes if present.[1]
- 2Clear the code and do a road test: if it does not return, it may be an intermittent fault or a cut-off triggered by a situation that has already been resolved.[1]
- 3Check fuses, shutoff relay, connectors and solenoid wiring, and the engine bay earths.[1][2]
- 4Use a multimeter to measure the solenoid's supply and resistance following the manufacturer's diagram.[1]
- 5Consider the ECU only when the solenoid, relay and wiring have been ruled out.[1][2]
Can I keep driving with P0215?
Garage soon
The sources differ: OBD-Codes.com rates it as serious because the conditions that cause it can prevent starting, although it notes that there are often no symptoms. It should be checked soon so you are not left stranded.[1][2]

Documented faults related to P0215
Known faults of specific engines and cars, with their repair cost, the affected years and their sources.
Control units and comfort electronics (BSI, SAM...): the most serious faults by engine and car
- High severityFrequency: CommonPeugeot 408Electronic faults with the doors, boot and screen (suspected BSI control unit)In 2025 Peugeot recalled around 60,000 2023-2024 Peugeot 308 and 408 cars (code MUV) over a software fault in the door control unit that can cause unintended opening or closing and disable the anti-trap protection on the windows; 408 owners also describe a power boot lid that will not open or close and a screen that goes black.
- High severityFrequency: CommonRenault Laguna IIMultiplex electrical system and hands-free card faultsThe Laguna II had a reputation problem because of faults in its multiplexed electrical network: the hands-free card, the card reader and the ABS, ESP and handbrake warning lights came on erratically, especially in the early years of production (2001-2003).
- Critical severityFrequency: OccasionalMazda MX-5 IVDC/DC converter control unit fault with risk of short circuit and fireA 2018 Safety Gate alert covers MX-5 ND models built between August 2014 and April 2017: the DC converter control unit could fail, cause a short circuit and damage the converter, with a risk of fire. It is a precautionary recall; check the chassis number at the official service centre.
- Medium severityFrequency: Very frequentFiat StiloElectrical and electronic faults in the multiplex systemThe Stilo has had a reputation for widespread electrical faults since its launch: poor contacts in the multiplex wiring, an instrument cluster that switches off and sensors that disconnect, sometimes while the car is running.
Injectors: the most serious faults by engine and car
- High severityFrequency: Very frequentOM651Delphi piezo injector failure (220/250 CDI)Yes: 220 and 250 CDI models built between 2008 and 2011 had Delphi piezo injectors that were prone to failing and seizing in the cylinder head. Mercedes-Benz replaced them under warranty in 2009 and switched the 220 CDI to solenoid injectors from 2010-2011, but the 250 CDI kept them.Repair (garage): €3,600–€5,900
- High severityFrequency: CommonBMW N52 / N53N53 piezoelectric injector failureThe N53's piezoelectric direct injectors fail frequently and cause misfires, rough idle and limp mode; replacing them is expensive and they must be coded.
- High severityFrequency: CommonMZR-CDOil dilution from leaking injector seals and DPF regenerationsOn the 2.0 and 2.2 MZR-CD, injector seals that age badly and incomplete particulate filter regenerations on short journeys can let unburnt diesel into the sump, diluting the oil and leaving the engine with less lubrication.
- High severityFrequency: CommonOM642Wear and failure of the Bosch piezo injectorsThe OM642's Bosch piezo injectors can fail from around 150,000-200,000 km, especially with poor-quality diesel; they cannot be repaired, only replaced. Because it is a V engine, those on the rear bank are harder to reach, which pushes up labour costs.Repair: €4,500–€6,500
Frequently asked questions
Can I drive with code P0215?
If the car runs normally you can get to the garage, but it should be checked soon: OBD-Codes.com warns that the causes can end up preventing starting.[1]
What is the engine shutoff solenoid?
It is an electric valve in the fuel circuit that the ECU operates to cut off the supply in specific situations, such as a collision or a rollover, according to OBD-Codes.com.[1]
What is the most likely cause of P0215?
The sources agree on the solenoid, the shutoff relay and the wiring. Start with fuses, connectors and the relay before suspecting the ECU.[1][2]
Will I pass the MOT with code P0215?
If the code has switched on the engine warning light, no: with that light on, the inspection records a serious defect, and on Euro 5 and Euro 6 cars the ITV (Spain's roadworthiness inspection, similar to the MOT) also reads the OBD diagnostic system. Repair the fault before you go; clearing the code just before the inspection does not help either, because it counts as a serious defect.[3]
