P15A0 Fault Code: Understanding The Description And Troubleshooting Steps
The P15A0 fault code refers to a problem with the Fuel Economy Mode Switch Circuit’s voltage being too high. The Engine Control Module (ECM) supplies a 5 V reference voltage to the fuel economy mode switch. When the switch button is pressed, it allows the voltage to bypass a resistor, signaling a fuel economy mode request.
This request is sent to the Transmission Control Module (TCM) and the Instrument Panel Cluster (IPC). The TCM then adjusts throttle progressions and transmission shift points to optimize fuel efficiency.
The IPC illuminates the fuel economy mode indicator lamp. To activate the fuel economy mode, the switch must be pressed for a specific duration, between 0.094-1.5 seconds.
