U1467 – Fuel Pump Control Module Communication Error

The ODBII code U1467 indicates a communication error between the fuel pump control module and the vehicle’s onboard diagnostic system, suggesting a potential issue with the module or its connections.

The severity of ODBII code U1467 is moderate to severe.

Common Causes For: U1465 U1465: “Control Module Communication Failure”

• Faulty fuel pump control module
• Damaged wiring or connectors
• Poor ground connections
• Failed fuel pump
• Issues with the engine control module (ECM)
• Corroded terminals
• Software glitches or updates needed
• Battery voltage issues
• Intermittent electrical connections
• Faulty relays or fuses

Common misdiagnosis for U1467 U1467: Fuel Pump Control Module Communication Error

• Faulty fuel pump
• Bad fuel pump relay
• Wiring issues or shorts in the fuel pump circuit
• Defective fuel pressure regulator
• Malfunctioning engine control module (ECM)
• Issues with the fuel level sensor
• Battery or charging system problems
• Corroded or loose connectors in the fuel system
• Faulty ignition switch
• Problems with the vehicle’s body control module (BCM)

Common Troubleshooting Steps

When dealing with OBD-II code U1467, which indicates a Fuel Pump Control Module Communication Error, there are several common troubleshooting steps you can follow to diagnose and potentially resolve the issue. Here’s a structured approach:

• Check for Additional Codes: Use an OBD-II scanner to check for any other trouble codes that may be present. Sometimes, multiple codes can provide more context for the issue.
• Inspect the Wiring and Connectors: **Visual Inspection: Check the wiring and connectors related to the fuel pump control module for any signs of damage, corrosion, or loose connections.
• **Connector Pins: Ensure that the pins in the connectors are not bent or corroded.
• Test the Fuel Pump Control Module: **Power and Ground: Verify that the fuel pump control module is receiving the correct power and ground signals. Use a multimeter to check voltage and ground continuity.
• **Module Functionality: If possible, test the fuel pump control module separately to ensure it is functioning correctly.
• Check the Fuel Pump: **Operation: Ensure that the fuel pump is operating correctly. You can listen for the pump’s operation when the ignition is turned on or use a fuel pressure gauge to check for proper fuel pressure.
• **Connections: Inspect the fuel pump connections for any issues.
• Inspect the CAN Bus Communication: **Communication Lines: Check the CAN bus communication lines for continuity and proper voltage levels. A fault in the communication lines can lead to communication errors.
• **Other Modules: Ensure that other modules on the CAN bus are functioning correctly, as a fault in one module can affect communication with others.
• Check for Short Circuits or Open Circuits: Use a multimeter to check for any short circuits or open circuits in the wiring harness related to the fuel pump control module.
• Update or Reprogram the Module: If the module is not responding correctly, check if there are any software updates or reprogramming procedures available from the manufacturer.
• Clear Codes and Test Drive: After performing the above checks and repairs, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns.
• Consult Technical Service Bulletins (TSBs): Check for any TSBs related to the U1467 code for your specific vehicle make and model. Manufacturers may have specific fixes or recommendations.
• Seek Professional Help: If you are unable to resolve the issue after these steps, it may be best to consult a professional mechanic or technician who has experience with your vehicle’s specific systems. By following these steps, you should be able to identify the root cause of the U1467 code and take appropriate action to resolve the issue.
