P2672: Injection Pump Timing Offset
The high-pressure injection pump timing is offset from the expected reference. On distributor pumps with a timing solenoid, the actuator does not match the commanded position.
What P2672 means
P2672 is a generic OBD-II powertrain code in the fuel & air group.

Common causes
- 01Worn timing actuator piston or sealMost likely
- 02Stretched pump drive chain or beltPossible
Can I drive with P2672?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P2672
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P2672. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Fix other faults first
If other codes are stored, start with power-supply, sensor-circuit and communication codes. They can cause this code as a side effect.
- 3
Check live data
Watch the related sensor and actuator readings in live data (Injection pump, Timing actuator) and compare them with expected values in the service information for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Worn timing actuator piston or seal; stretched pump drive chain or belt. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.

P2672 FAQ
What does P2672 mean?
P2672 means “Injection Pump Timing Offset”. The high-pressure injection pump timing is offset from the expected reference. On distributor pumps with a timing solenoid, the actuator does not match the commanded position.
Is P2672 serious? Can I keep driving?
We rate P2672 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P2672?
The most common causes, from most to least likely: Worn timing actuator piston or seal; Stretched pump drive chain or belt. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P2672?
Typical labor is about $375–$1,000 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P2672 myself?
DIY difficulty is hard. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will P2672 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
