P027A - FUEL PUMP MODULE B CONTROL CIRCUIT/OPEN
| Description: The 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 FPC voltage is less than or greater than a calibrated limit, for a calibrated amount of time. | |||
