Code P062B Acura Description

The injector supplies fuel to the engine and its fuel pressure is adjusted by a high-pressure fuel pump output duty cycle and controlled by the Powertrain Control Module (PCM) ON/OFF command. In the PCM, the injector driver receives commands from the CPU and drives injectors and solenoids. Also, the CPU sets the current to drive injectors and solenoids and transmits the current to the injector driver. If an abnormal communication occurs in the PCM, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
