P025A - FUEL PUMP MODULE CONTROL CIRCUIT/OPEN
| Description: | The powertrain control module (PCM) monitors the fuel pump command (FPC) circuit for a concern. When the PCM commands the fuel pump (FP) on, the PCM is able to detect a short to voltage on the FPC circuit. When the PCM commands the FP off, the PCM is able to detect an open circuit or a short to ground on the FPC circuit. The test fails if the voltage is less than or greater than a calibrated limit, for a calibrated amount of time. | ||
