This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the timing of the fuel pump is not right. It's like the pump is not giving fuel to the engine at the right time, which can make the car run poorly.
The engine control module (ECM) detects that the timing of the injection pump is not within the expected range. This can affect engine performance and efficiency.
The P2672 code is set when the ECM detects that the injection pump timing is offset from the manufacturer's specified range. This could be due to mechanical misalignment, sensor issues, or electrical problems affecting the timing signals.
• Engine misfires
• Poor fuel economy
• Rough idling
• Mechanical misalignment of the injection pump
• Faulty timing sensor
• Wiring issues or poor electrical connections
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Check for any other related codes and address them first.
• Inspect the injection pump and timing components for mechanical issues.
• Test the timing sensor and related wiring for faults.
• Realign the injection pump to the correct timing position.
• Replace the faulty timing sensor if necessary.
• Repair or replace damaged wiring or connectors.
• OBD-II scanner
• Timing light
• Multimeter

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram 2500
• Regularly maintain the fuel system.
• Ensure proper installation of timing components.
• Check and replace timing sensors as needed.
Engine Performance
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult with a professional mechanic for accurate diagnosis and repair.
Check with the vehicle manufacturer for warranty coverage on fuel system components.
This code has been associated with vehicles that have high mileage or have had previous fuel system repairs.
Moderate – It should be addressed soon to prevent potential engine damage.
Operating a vehicle with this issue may lead to increased emissions and reduced fuel efficiency.
• Engine at operating temperature
• Vehicle in a stationary position
The injection pump is typically located near the front of the engine, driven by the timing belt or chain.
Q: Can I drive with a P2672 code?
A: It's not recommended to drive with this code as it can lead to engine damage over time.
Q: How can I prevent a P2672 code?
A: Regular maintenance of the fuel system and ensuring proper installation of timing components can help prevent this code.
