Code P050D Honda Description

The quick warm-up system supplies additional air and retards the ignition timing when the engine is cold to activate the catalytic converter as quickly as possible. When the actual amount of air is less than the target amount, the Powertrain Control Module (PCM) detects a malfunction and stores a Diagnostic Trouble Code (DTC). The DTC will be set when the engine speed is 2,400 rpm or more for at least 3.5 seconds.
