DTC P0453: Evaporative Emission Control System Pressure Sensor High Input: Description

To judge if the fuel tank differential pressure sensor is defective, the ECM (M/T) or PCM (A/T) monitors the fuel tank differential pressure sensor output voltage. Based on the test conditions and judgment criteria, the ECM (M/T) or PCM (A/T) judges if the fuel tank differential pressure sensor output voltage is normal. See Figure , Figure , Figure and Figure .
