P0A05 - MOTOR ELECTRONICS COOLANT PUMP (MECP) CONTROL CIRCUIT OPEN
| Description: | The powertrain control module (PCM) monitors the MECP primary circuit output. The test fails if: the PCM grounds the MECP circuit, and excessive current draw is detected on the MECP circuit; or, with the MECP circuit not grounded by the PCM, voltage is not detected on the MECP circuit. The PCM expects to detect VPWR voltage coming through the MECP relay coil to the MECP circuit. | |||
| Possible Causes: |

| Diagnostic Aids: | When the MECP_F PID displays YES, a concern is present. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
