Injection Pump Timing Offset
The P2672 code indicates that the Engine Control Module (ECM) has detected that the injection pump timing is outside the expected range. This can be caused by mechanical wear, sensor faults, or calibration issues. The ECM uses timing data to optimize fuel delivery for performance and emissions; an offset can lead to poor engine operation.
01. Most Common Causes
- Faulty injection pump timing sensor
- Worn or stretched timing belt/chain
- ECM calibration error
- Mechanical wear in injection pump
02. Symptoms You Will Notice
- Check Engine Light on
- Engine misfire or rough idle
- Reduced fuel economy
- Hard starting or excessive smoke
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Inspect timing belt/chain condition and tension.
Step 3: Test injection pump timing sensor and wiring.
Step 4: Check ECM calibration and update if necessary.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as incorrect timing can cause engine damage and poor performance.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150, while repairs can range from $200 for a sensor to $1000+ for pump or timing components.
