Injection Timing Control Circuit Malfunction
The P0216 code means the vehicle's onboard diagnostic system has detected: Injection Timing Control Circuit Malfunction. This is a critical severity code.

Common Symptoms
- Check Engine Light on
- Engine will not start or starts and immediately stalls
- Severe engine knock or detonation
- Excessive white or black exhaust smoke
- Significant loss of power
Probable Causes (Ranked by Likelihood)
- Failed injection timing stepper motor or solenoid Very High
- Wiring issue in the timing control circuit High
- Faulty injection pump timing mechanism Moderate
- Worn timing belt or chain affecting pump drive Moderate
- PCM timing control driver failure Low
Step-by-Step Diagnostic Procedure
-
Use a scan tool to read actual vs. desired injection timing. Significant deviation confirms a timing control problem.
-
Check the injection timing control solenoid or stepper motor for proper resistance per manufacturer specifications.
-
Verify power and ground to the timing control circuit at the solenoid connector.
-
On diesel engines with mechanical injection pumps, check the timing advance mechanism for seized or worn components.
-
Inspect the timing belt or chain that drives the injection pump for proper alignment and wear.
Common Fixes by Vehicle
What techs usually find when diagnosing P0216 on specific vehicles — tap your vehicle for the fix and the exact part:
1999-2003 Ford 7.3L Powerstroke Diesel Moderate DIY
Injection timing control circuit — on the 7.3L, check the IPR (Injection Pressure Regulator) valve for stuck open/closed. Also inspect the ICP (Injection Control Pressure) sensor for oil contamination at the connector. Replace IPR if sticking; these are very common failures.
Labor: 2-3 hr2004-2006 VW/Audi TDI 1.9L/2.0L PD Moderate DIY
Injection timing deviation on PD TDI — usually a failing N75 boost control valve or leaking PD injector o-rings. Test N75 with VCDS and replace if out of spec. If code pairs with low power complaints, suspect fuel pump cam follower wear (common PD failure).
Labor: 1-2 hr2003-2007 Dodge Ram Cummins 5.9L Moderate DIY
Injection timing fault — check the camshaft position sensor and crankshaft sensor for signal integrity. Replace the CKP first (most common cause). Verify fuel pressure and fuel system integrity; a failing lift pump causes similar symptoms on 5.9L Cummins.
Labor: 1-2 hrFrequently Asked Questions
Can I drive with code P0216?
No. Incorrect injection timing can cause severe engine knock, potential piston damage, and excessive exhaust temperatures. Do not drive the vehicle -- have it towed to a diesel specialist.
Is P0216 a serious code?
Yes, P0216 is a critical code, especially on diesel engines. Incorrect injection timing can cause catastrophic engine damage including cracked pistons, bent connecting rods, and destroyed turbochargers from excessive exhaust temperatures.
Is P0216 common on the Cummins 5.9L?
Yes. The 5.9L Cummins with the VP44 injection pump is notorious for P0216, often caused by a failing pump, lift pump issues causing low fuel pressure to the VP44, or electrical problems in the timing control circuit.
