The P129E fault code indicates an issue with the Fuel Pump Driver Control Module Signal Message Counter I. This code is triggered when the Engine Control Module (ECM) detects that there are too many error values in the serial data messages being sent by the Fuel Pump Power Control Module.

The Fuel Pump Power Control Module continuously sends data messages to the ECM, providing information about the fuel pump power control system’s operating state.

These messages are sent in a repeating series of rolling counts, each assigned a value.

However, if the ECM detects that a significant number of these counts contain error values, it will set the P129E Diagnostic Trouble Code (DTC).

When this fault code is present, it indicates that there may be a problem with the communication between the Fuel Pump Power Control Module and the ECM.

It is important to address this issue promptly to ensure proper functioning of the fuel pump and the overall performance of the vehicle.

What are the possible causes of the automobile fault code P129e?

If you see the engine light or service engine soon warning light on, the fault code P129e could be the culprit. This code is often caused by a faulty fuel pump power control module or issues with the module’s harness, such as an open or shorted circuit. To fix the problem, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded pins on the connectors.

How can I visually inspect the wiring harness and connectors to fix the P129e fault code?
