What P2672 means
On diesels with an electronically controlled rotary or distributor pump, the controller needs to know how far the pump's actual delivery start sits from its nominal position relative to the crankshaft. P2672 flags that this stored or measured offset is wrong or outside the window the software accepts. CARB requires 2010-on diesels to detect injection that is too early or too late. Dodge listed P2672 among the codes activated by the engine-controller update in emissions recall T21 for the 2004–2006 Sprinter; no public maker text gives a threshold. P2673 instead means the timing value was never learned. A driver may notice hard starting, knocking, smoke or reduced power.

Symptoms of P2672
- Check engine light on
- Hard starting or rough idle
- Diesel knock, smoke or reduced power
Common causes of P2672
- Most likelyInjection pump fitted or re-timed incorrectly after repair
- PossibleFaulty pump timing or crank/cam reference signal
- Less likelyWorn pump drive (gear, belt, coupling) shifting the timing
- Less likelyEngine control software fault or wrong calibration
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2672 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 6 | Area: computer (engine control module) and output circuits. |
| 72 | The exact fault in that area. |
What to do next
- Note P2672 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2672
What does P2672 mean?
P2672 means "Injection Pump Timing Offset". On diesels with an electronically controlled rotary or distributor pump, the controller needs to know how far the pump's actual delivery start sits from its nominal position relative to the crankshaft. It is a generic code, so it means the same on every make.
Is it safe to drive with P2672?
Drive gently and only to a workshop. With P2672 the car can go into limp mode (reduced power) to protect itself.
Will P2672 fail an emissions test?
Yes, it can. P2672 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2672 to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P2672 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
