P2283
Injector Control Pressure Sensor Circuit
- Severity
- High
- Driving
- Drive only to a garage
A fault in the injector control pressure sensor circuit. Some diesels fire their injectors using engine oil at very high pressure rather than electrically, and this sensor reports that pressure. Without it the module cannot control injection at all.
Possible causes
- CommonLow engine oil level, or oil of the wrong grade
- CommonFailed injector control pressure sensor
- CommonCorroded or oil-contaminated connector
- CommonLeaking high-pressure oil rail, fitting or standpipe
- PossibleFailed high-pressure oil pump
- PossibleFailed pressure regulator valve
What you might notice
- Hard starting or no start
- Rough running and misfire
- Loss of power
- White smoke on start-up
- Check engine light on
What to check, in order
- Check the engine oil level, condition and grade first. These systems use engine oil at very high pressure to fire the injectors, so oil that is low, degraded or the wrong grade causes faults here before anything else does.
- Inspect the connector for oil contamination - a leaking sensor seal fills its own plug.
- Watch the reported pressure on the live data screen during cranking and at idle.
- Look for external oil leaks around the high-pressure rail and its fittings.
- Read all codes. A pressure-too-low code alongside a sensor code usually means the pressure is genuinely low and the sensor is right.
