P2284 - INJECTOR CONTROL PRESSURE SENSOR CIRCUIT RANGE/PERFORMANCE
| Description: | The powertrain control module (PCM) monitors if the desired injection control pressure (ICP) is equal to the measured ICP while the engine is running. If the measured ICP does not reasonably compare to the desired ICP, the PCM sets the DTC, ignores the measured ICP sensor signal and attempts to control the engine with the desired value. | |||
| 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 a biased ICP sensor. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
