P2623 - INJECTOR CONTROL PRESSURE REGULATOR/OPEN
| Description: | The powertrain control module (PCM) monitors the injection control pressure (ICP) while the engine is running and then compares it to the desired ICP. If the measured ICP does not reasonably compare to the desired ICP, the PCM ignores the measured ICP sensor signal and attempts to control the engine with the desired value. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | An open circuit results in minimal oil pressure and a no-start situation. A short to ground in a circuit results in maximum oil pressure. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
