P2672 Injection Pump Timing Offset

Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modePossible

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.

Likely causes

Injection pump fitted or re-timed incorrectly after repair
Faulty pump timing or crank/cam reference signal
Worn pump drive (gear, belt, coupling) shifting the timing
Engine control software fault or wrong calibration

Symptoms

  • Check engine light on
  • Hard starting or rough idle
  • Diesel knock, smoke or reduced power
