P2289 - INJECTOR CONTROL PRESSURE TOO HIGH - ENGINE OFF
| Description: | The powertrain control module (PCM) monitors the injection control pressure (ICP) while the key is ON, and the engine is OFF. If the PCM detects an out of range high or low ICP sensor, the malfunction indicator lamp (MIL) is illuminated and the PCM functions from an estimated injection control pressure (open loop control of injection control pressure). | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | The ICP sensor bias varies between sensors. The amount of voltage the sensor deviates from a calculated reference value (sensor bias) may cause an injection control pressure calculation error. Check for input sensor bias. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
