SB-14-012 A subject vehicle may exhibit an illuminated check engine lamp with DTC (Diagnostic Trouble Code) P0421 (Catalyst efficiency below threshold). The engine ECU may falsely detect an issue with the ATC (After Turbo Catalyst) with the current ECU software. If DTC P0421 is stored in the engine ECU, reprogram the ECU to the latest software level prior to suspecting a fault with the ATC.

Due to variations in production, certain exhaust manifold mounted catalytic converters may experience catalyst layer separation on affected vehicles. If this occurs, the MIL will illuminate with DTC P0421 or P0431, "Warm Up Catalyst Efficiency Below Threshold" stored in the PCM. Mitsubishi Motors North America, Inc. is extending the catalytic converter warranty only on affected vehicles currently registered in certain states from 8 years / 80,000 miles to 10 years / 120,000 miles.
