P0216 Code: Injection Timing Control Circuit Malfunction
🟠 Moderate severity · drivable
Yes, but the engine may lose power, run rough, or go into limp mode — get it checked soon.
What P0216 means
On diesel engines with electronically controlled injection pumps, the computer adjusts when fuel is injected. This code means the computer detects a problem in the injection timing control circuit. The engine may run poorly, smoke, lose power, or go into a reduced-power mode.
Symptoms
- Check engine light on
- Loss of power
- Rough running
- Excessive exhaust smoke
- Poor fuel economy
Common causes
- most common: Faulty injection timing control actuator or solenoid
- common: Damaged wiring or connector in the circuit
- less common: Worn or failed injection pump components
- rare: Engine computer (PCM) fault
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Replace the injection timing control actuator or solenoid | Mechanic | $150–500 |
| Inspect and repair the wiring or connector | Yes | $20–120 |
Frequently asked questions
Can I drive with a P0216 code?
Usually yes, but the engine may lose power, run rough, or enter limp mode. Have it diagnosed soon.
What does P0216 mean on a diesel?
It means the computer has a problem controlling when fuel is injected, often due to a bad timing actuator, solenoid, or wiring.
How much does it cost to fix a P0216?
Replacing the timing control actuator usually runs $150–500, plus labor. Wiring repairs are typically $20–120.
