DTC P0452: Evaporative Emission Control System Pressure Sensor Low 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.
