Code P1280 Description

The P1280 diagnostic trouble code indicates that the Injection Control Pressure (ICP) is out of range low. This means that the pressure of the oil being supplied to the injectors in the high-pressure oil system is below the expected level. The ICP sensor monitors the pressure of the oil in the high-pressure oil system and sends this information to the Powertrain Control Module (PCM). When the pressure is too low, it can lead to issues with fuel injection and overall engine performance.
