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 engine speed is a specified fast idle value, and it continues for a specified time, the powertrain control module (PCM) detects a malfunction and stores a DTC.
