P129D Fault Code: Understanding The Engine Overheating Issue
The P129D fault code refers to a problem with the Fuel Pump Power Control Module. This module is responsible for monitoring the ignition voltage circuit in the vehicle to ensure it is operating within the normal range. When the voltage falls below a calibrated value for 1 second, the Diagnostic Trouble Code (DTC) is triggered.
In simpler terms, the P129D code indicates that there is a low voltage issue with the ignition switch circuit of the Fuel Pump Driver Control Module. This can potentially affect the performance of the fuel pump, which is responsible for delivering fuel to the engine.
If you encounter this fault code, it is important to have it addressed promptly. Ignoring the issue can lead to problems with fuel delivery, which can result in poor engine performance or even engine stalling. A qualified mechanic will be able to diagnose the exact cause of the low voltage and make the necessary repairs to ensure your vehicle is running smoothly and efficiently.
