P2283 to P2292 and P2623 to P2625: injector control pressure and its regulator
On a diesel with hydraulically actuated injectors, the injector control pressure sensor has a fault, the pressure is too low or too high, or erratic, with the engine running, off or cranking, or the injector control pressure regulator circuit has a fault.

Can you keep driving?Only as far as the workshopWhat does P2283 mean?
Some diesel engines, often in pickups and trucks, use engine oil at high pressure to fire the injectors instead of a fuel rail. A high pressure oil pump builds that pressure, a regulator controls it and a sensor reports it. If the pressure is too low, the injectors cannot fire properly, so the engine starts hard, lacks power or will not start at all. Low oil, the wrong oil, leaking seals in the high pressure system or a worn pump are the usual causes.
What causes P2283?
- Low engine oil, or oil of the wrong grade
- A leak in the high pressure oil system, often at injector or rail seals
- A failed injector control pressure regulator
- A worn high pressure oil pump
- A failed pressure sensor or a damaged wire to it
What to check first for P2283
- Check the engine oil level and grade first
- Compare the desired and actual injector control pressure on a scan tool while cranking and running
- Have the high pressure system checked for leaks
- Inspect the pressure sensor and regulator connectors
Can you drive with P2283?
Drive only to a workshop, gently. The engine may lose power or stall; if it will not start, or cranks for a long time before starting, have it towed rather than draining the battery.
In states with an OBD-II emissions inspection, a car with the check engine light on fails the test until the fault is fixed.
