P15A1 Fault Code: Understanding The Description And Troubleshooting Steps
The P15A1 fault code refers to a problem with the Fuel Economy Mode Switch. The Engine Control Module (ECM) supplies a 5 V reference voltage to the switch, which causes current to flow through a series of resistors. The ECM monitors the reference voltage and detects any changes when the switch button is pressed.
When the switch button is pressed, the resulting voltage drop is detected by the ECM as a fuel economy mode request. The ECM then sends a message to the Transmission Control Module (TCM) to modify throttle progressions and transmission shift points for optimal fuel efficiency. The Instrument Panel Cluster (IPC) also receives the fuel economy mode request and illuminates the fuel economy mode indicator lamp.
To activate the fuel economy mode, the switch must be pressed for a duration between 0.094-1.5 seconds. In summary, the P15A1 fault code indicates a performance issue with the Fuel Economy Mode Switch, which affects the optimization of fuel efficiency in the vehicle.
