P2672 Fault Code

Injection Pump Timing Offset

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2672 fault code refers to the Injection Pump Timing Offset, which indicates that the timing of the fuel injection pump is not aligned as per the manufacturer's specifications. This misalignment can lead to inefficient engine performance, increased emissions, and potential damage to the engine if not resolved promptly.

• The injection pump is a critical component in the diesel engine's fuel system.
• Timing refers to the precise moment when fuel is injected into the combustion chamber in relation to the piston’s position.
• An incorrect timing offset can cause a variety of engine performance issues.

What are the symptoms of the P2672 code?

When the P2672 code is active, you may experience symptoms such as:

• Poor fuel efficiency and increased fuel consumption.
• Engine misfires and rough idling.
• Difficulty starting the engine or prolonged cranking.
• Increased exhaust smoke, particularly white smoke, indicating incomplete combustion.
• A noticeable decrease in engine power and acceleration.

What causes the P2672 code?

Several factors can lead to the P2672 fault code, including:

• Wear and tear in the injection pump or related components.
• Incorrect installation or calibration of the injection pump.
• Failed or malfunctioning sensors that monitor pump timing.
• Contamination in the fuel system affecting pump operation.
• Mechanical issues such as damaged gears or timing belts that affect the pump's operation.

How to fix P2672?

To address the P2672 fault code, the following steps may be taken:

• Use a diagnostic scanner to check for additional codes and pinpoint the issue.
• Inspect the injection pump and its timing mechanism for any visible damage or wear.
• Re-calibrate or replace the injection pump if it is found to be faulty.
• Check and replace any faulty sensors related to the pump timing.
• Ensure that the timing belt or gear is properly aligned and in good condition.
• Clear the fault code and test drive the vehicle to verify the fix.
