P2284 Fault Code
P2284 OBD-II Trouble Code Short Description
Injector Control Pressure Sensor Circuit Range/Performance
What does trouble code P2284 mean?
The P2284 code indicates a malfunction in the Injector Control Pressure Sensor Circuit. This sensor plays a critical role in measuring the pressure of the fuel in the common rail system, allowing the ECM to adjust fuel delivery to maintain optimal engine performance. When this sensor operates outside its designed range or fails to perform effectively, it can lead to errors in fuel injection, which may affect engine efficiency and emissions.
