Step-by-step diagnostic guide
Follow the outlined procedure to diagnose this DTC by eliminating possible causes one by one.
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to see if any related codes are present, which could provide additional clues. | OBD-II Scanner |
| Inspect the Injection Pump Fuel Metering Control “B” | Visually inspect the injection pump fuel metering control B and its connections for signs of damage or intermittent operation. | Flashlight, Safety Gloves |
| Perform a Wiggle Test | While monitoring the circuit, gently wiggle the wiring and connectors to see if the issue can be replicated, indicating an intermittent connection. | Multimeter, Diagnostic Software |
| Check Wiring and Connectors | Inspect all wiring and connectors leading to the injection pump for any signs of wear, corrosion, or loose connections. | Flashlight, Multimeter |
| Repair or Replace Faulty Wiring/Components | If any faulty wiring or components are found, repair or replace them. Ensure all connections are secure and free from corrosion. | Wire Strippers, Electrical Tape, Replacement Wires/Connectors |
| Check the PCM (Powertrain Control Module) | Inspect the PCM for any faults or intermittent operation. If suspected to be faulty, it may need reprogramming or replacement. | OBD-II Scanner, Multimeter |
| Clear the Code and Test Drive | After making necessary repairs, clear the P0260 code with an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0260 code has not returned. If it does, further diagnosis may be needed. | OBD-II Scanner |
