DTC P0452: Evaporative Emission Control System Pressure Sensor Low Input: Operation

A 5-volt voltage is supplied to the power terminal of the fuel tank differential pressure sensor (terminal No. 3) from the ECM (terminal No. 81 - M/T) or PCM (terminal No. 46 - A/T). The ground terminal (terminal No. 2) is grounded with the ECM (terminal No. 92 - M/T) or PCM (terminal No. 57 - A/T). A voltage proportional to the pressure in the fuel tank is sent from the output terminal of the fuel tank differential pressure sensor (terminal No. 1) to the ECM (terminal No. 61 - M/T) or PCM (terminal No. 92 - A/T).
