P2283
Injector Control Pressure Sensor Circuit
Fuel injection (diesel)
Generic OBD-II
Medium
What it means
P2283 means the control module has seen a fault in the injector control pressure (ICP) sensor circuit — the sensor that reports the high oil pressure used to fire the injectors on these diesel engines. Because injection timing depends on this reading, the fault can cause hard starting, rough running, or low power until it is corrected.
Medium
Can I keep driving? Drivable but watch for hard starting, stumbling, or low power — on these diesel systems bad injection-pressure data can cause stalling, so drive with caution.
Common symptoms
What you'll notice
- Check-engine light on
- Hard starting or extended cranking
- Rough running, hesitation, or reduced power
- Possible stalling in some conditions
Common causes
Most likely first
- Failed injection control pressure (ICP) sensorLikely
- Oil or fuel contamination at the sensor connectorCommon
- Open, shorted, or chafed wiring in the sensor circuitCommon
- Corroded or loose sensor connectorLess often
- Fault in the reference voltage or ground from the control moduleLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and note the reported injection control pressure.
- Inspect the ICP sensor connector for oil intrusion, corrosion, or bent pins.
- Check the signal, reference, and ground wires for opens or shorts.
- Compare live sensor voltage against the expected key-on value.
- Replace the ICP sensor if the circuit checks good but the reading is implausible, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2283?+
Short trips are usually possible, but bad pressure data can cause hard starts or stalling, so repair it promptly.
Can I just clear P2283?+
It will return once the module rechecks the circuit unless the sensor or its wiring is repaired.
