What Does P0216 Mean?
This code indicates a malfunction in the injection timing control circuit, typically on diesel engines with electronically controlled injection pumps. The ECM has detected that the timing control solenoid or actuator in the injection pump is not responding correctly to commands, which affects fuel injection timing and engine performance.
Common Causes
35%
Faulty injection timing control solenoid inside the injection pump with worn coil or stuck actuator
25%
Damaged wiring or connector at the injection timing solenoid, often from heat and vibration near the pump
25%
Worn injection pump timing advance mechanism including advance piston, springs, or internal fuel passages
15%
ECM driver circuit failure for the injection timing control output
Diagnostic Steps
1
Step 1: Measure the injection timing control solenoid resistance at the connector. Compare to specification (typically 5-12 ohms). Replace if out of range.
2
Step 2: Monitor injection timing actual versus desired values on a scan tool at various RPMs. A large offset that does not respond to ECM commands indicates a mechanical or electrical fault in the timing actuator.
3
Step 3: Check the timing solenoid wiring for damage, particularly where it attaches to the injection pump. The vibration and heat in this area accelerate wire deterioration.
4
Step 4: Using a scan tool, command the timing solenoid through its range and listen for actuation or feel for movement at the pump. No response confirms solenoid or internal pump failure.
5
Step 5: If the solenoid tests good, the injection pump internal timing advance mechanism may be worn. This typically requires pump removal and rebuilding or replacement.

The most common cause of P0216 (Injection Timing Control Circuit Malfunction) is: Faulty injection timing control solenoid inside the injection pump with worn coil or stuck actuator
Typical repair costs for P0216 range from $300 to $1,800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Incorrect diesel injection timing causes excessive smoke, increased noise, poor fuel economy, and reduced power. Severely advanced timing can cause destructive detonation, while retarded timing causes excessive exhaust temperatures that can damage the turbocharger.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0216 to identify the root cause.
