What causes Mitsubishi OBDII engine light to go off?
P0421 MITSUBISHI Possible Causes. Warm Up Three Way Catalytic converter deterioration or malfunction. Exhaust system leaks. Loose front or rear HO2Ss. Faulty front heater O2 sensor. O2 sensors harness is open or shorted. O2 sensors poor electrical connection.
What does error code p0421 mean on catalytic converter?
Error Code P0421 is described as Warm Up Catalyst Efficiency Below Threshold (Bank 1). This means the Catalytic Converter’s Oxygen Sensor Downstream has detected that the Bank 1 converter is not working properly.
What is the OBD code for a Mitsubishi?
What about the obd code? The P0421 Mitsubishi code is set when the Engine Control Module (ECM) detects rear HO2S value difference becomes closer to value of front HO2S. The ECM monitors when vehicle speed is 25-60 MPH, load is 22-45 percent and engine speed is 1000-3000 RPM.

What does it mean to have an error code P0420?
However, it is important to note that, if this Error Code shows up, or other related codes such as P0420, P0430 and P0431, it doesn’t always automatically mean that the converter is in bad shape. Rather, all these codes simply mean the converter is running below the efficiency it is expected for, or it is running below threshold.
