Possible causes – Throttle Position Sensor (TPS) harness is open or shorted– Throttle Position Sensor (TPS) circuit poor electrical connection– Faulty Throttle Position Sensor (TPS)– Fault Electric Throttle Control Actuator (or Throttle Body Motor)– Accelerator Pedal Position Sensor (APP) When is the obd code mean? An unexpected voltage from the Throttle Position Sensor (TPS) is…

Possible causes – Turbocharger wastegate actuator failure– Charging pressure control system faulty Symptoms – Engine Light ON (or Service Engine Soon Warning Light) P0234 MITSUBISHI OBD Code Description The boost pressure sensor responds to pressure changes in the intake manifold. This pressure is created by the turbocharger and changes with accelerator pedal position (APP) and…

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 Tech description As the code description implies the P0421 code means that the vehicle’s control module has detected…
