The cold start emission reduction process controls the air fuel ratio to lean when the engine is cold to lower emissions as the catalyst is not warmed up. If the ignition timing has not been retarded to the specified value for a specified time, the powertrain control module (PCM) detects a malfunction and stores a DTC.
