P0627 - FUEL PUMP A CONTROL CIRCUIT/OPEN
| Description: The powertrain control module (PCM) monitors the fuel pump command (FPC) circuit output from the PCM. The test fails if the FPC output is commanded OFF and the FPC circuit voltage is lower than an expected threshold, when the PCM expects to detect B+ voltage coming through the fuel pump relay coil to the FPC circuit. | |||
