P0216Injector/Injection Timing Control Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0216 is a diesel code for the control of injection timing. On 1990s distributor pumps with an electronic timing advance it meant that actual injection timing missed its target; today manufacturers use it for the electronic injector control, with different meanings. GM's Duramax diesels compare, inside the engine module, the summed injection pulse widths from the hardware driver with those calculated by the software; a mismatch in 30 of 124 or 60 consecutive checks sets the code with the warning light in the first trip. On GM's 3.0 litre LM2 it appeared together with P0202 from a broken pin in the injector 2 connector. Saab's 3.0 V6 diesel uses it for a fault in the separate injector power stage. The result can be loss of power, rough running, smoke and limp mode.
- What you may notice
- Check engine light on
- Loss of power, limp mode
- Rough running, jerking
- Hard starting or stalling (distributor pump), smoke
- Likely causes
- PossibleInjector harness or connector (broken pin) – common rail
- PossibleEngine module or injector power stage faulty internally
- PossibleDistributor pump electronics or timing advance faulty
- PossibleLow supply pressure on distributor pumps (lift pump, filter)
- RarePump installed incorrectly, drive gear misaligned
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
