Code P0443 Honda Description

The Evaporative Emission (EVAP) Canister Purge Valve is attached to the vacuum port between the intake manifold and the EVAP canister. The Powertrain Control Module (PCM) does not turn on the EVAP canister purge valve when the engine coolant temperature is less than a specified value. The PCM adjusts the amount of fuel vapor sent to the engine by controlling the EVAP canister purge valve duty cycle. When the return signal does not change according to the EVAP canister purge valve output for a set time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
