P2672 — Injection Pump Timing Offset
powertrain (engine/transmission)
Is it safe to drive?
Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
How to diagnose with an OBD scanner
- Read the code and freeze frame Connect an OBD2 scanner, confirm P2672 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
- Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
- Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the injection pump timing offset for damage, corrosion, chafing or poor contact.
- Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
- Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
- Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2672 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for P2672 (parts and labor, USD, independent shop rates): Repair wiring or connectors: $80–$250; Control module repair: $300–$1,000; Replace the faulty sensor or actuator: $150–$500. Overall, fixing P2672 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.
Common questions
Will P2672 clear itself?
Sometimes P2672 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.
What is the most common cause of P2672?
The most common causes are: open or shorted wiring in the circuit, blown fuse feeding the circuit, corroded, loose or damaged connector.
How much does it cost to fix P2672?
Repair wiring or connectors — $80–$250; Control module repair — $300–$1,000; Replace the faulty sensor or actuator — $150–$500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.
How do I diagnose P2672 myself?
Start with a scan: confirm P2672, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the sensor and actuator circuits, and verify the suspect component against live data before buying parts.
What are the symptoms of P2672?
Drivers most often notice: increased fuel consumption in some cases, Check Engine Light on, possible limp mode depending on the affected component, the affected system operates intermittently or not at all.
What does P2672 mean?
P2672 is logged by the onboard diagnostics when the sensor and actuator circuits does not behave as expected. The official definition is “Injection Pump Timing Offset”. This is a powertrain (engine/transmission) category code.
The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2672 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.
Common symptoms of P2672
- increased fuel consumption in some cases
- Check Engine Light on
- possible limp mode depending on the affected component
- the affected system operates intermittently or not at all
What causes P2672?
- corroded, loose or damaged connector
- poor ground connection
- control module driver fault
- blown fuse feeding the circuit
- open or shorted wiring in the circuit
- faulty sensor or actuator of the affected circuit
