Code P0202 Honda Description

The injector supplies fuel to the engine and is controlled by the Powertrain Control Module (PCM) ON/OFF command. In the PCM, the injector driver receives a drive command from the Central processing unit (CPU) and drives the injector. The CPU monitors injector currents and returns a signal from the injector driver to monitor the terminal voltage of PCM. If the monitored conditions are abnormal for a specified time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
