P15Df Fault Code: Understanding The Description And Troubleshooting Steps
The P15DF fault code indicates that there is a problem with the high-pressure fuel system during the catalyst preheating phase. The Engine Control Module (ECM) keeps an eye on the Rail-Pressure Sensor to ensure that the pressure levels are within the specified range.
If the Rail-Pressure Sensor does not meet the factory specifications, the ECM will trigger the P15DF code.
This code specifically points to a cold start fuel pressure that is too low in one of the engine banks.
It is important to address this issue promptly to ensure proper fuel delivery and engine performance.
