The P2672: Injection Pump Timing Offset refers to an issue where the timing of the injection pump is not aligned correctly with the manufacturer’s specifications. This can be caused by calibration issues, incorrect timing settings, or problems with the timing sensors, leading to improper fuel delivery and engine performance problems.
P2672 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2672: Injection Pump Timing Offset |
| Is it serious? | Yes, incorrect injection pump timing can lead to poor engine performance, increased emissions, and potential engine damage. |
| Possible causes | – Incorrect injection pump timing – Timing calibration issues – Faulty timing sensors |
| How to diagnose? | – Verify the injection pump timing against specifications – Check and adjust timing calibration if necessary – Inspect timing sensors for faults – Replace faulty components as needed |
P2672 Meaning
The P2672: Injection Pump Timing Offset code indicates that the timing of the injection pump is incorrect, which means the fuel injection is occurring either too early or too late compared to the optimal timing for engine operation. This misalignment can lead to reduced engine efficiency, increased fuel consumption, higher emissions, and even risk of engine damage if left unresolved. This issue may be caused by improper calibration, mechanical misalignment, or a failure in one or more timing sensors.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to identify if there are any additional related codes that may provide further diagnostic information. | OBD-II Scanner |
| Verify Injection Pump Timing | Measure the injection pump timing and compare it against the manufacturer’s specifications to determine if it is misaligned. | Timing Light, Manufacturer’s Specifications |
| Check Timing Calibration | If the timing is incorrect, adjust the injection pump timing calibration to match the specifications. Ensure the engine timing marks are aligned correctly. | Timing Adjustment Tool |
| Inspect Timing Sensors | Inspect the timing sensors for any visible signs of damage, incorrect readings, or failures. Replace any faulty sensors. | Multimeter, Diagnostic Tool |
| Check Wiring and Connections | Inspect the wiring and connectors leading to the injection pump and timing sensors for any signs of damage, corrosion, or disconnections. | Flashlight, Multimeter |
| Replace Faulty Components | Replace any components that are found to be faulty, such as timing sensors, wiring, or connectors to restore proper functionality. | Replacement Parts |
| Clear the Code and Test Drive | After making the necessary adjustments or replacing components, clear the code using an OBD-II scanner and take the vehicle for a test drive to verify that the timing is now correct. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the vehicle to ensure the P2672 code does not return and that the engine is performing efficiently. | OBD-II Scanner |
