Code P0088 2020 Honda CR-V Description

The Powertrain Control Module (PCM) controls fuel pressure delivered by the high-pressure fuel pump. If the actual fuel pressure deviates from the target fuel pressure for a set time, the PCM detects a malfunction. The Diagnostic Trouble Code (DTC) is also stored when the pressure relief valve is opened to protect the fuel hose when the fuel reaches abnormally high pressure.
