DTC P0182: Fuel Temperature Sensor Circuit Low Input: Operation

A 5-volt voltage is applied to fuel temperature sensor output terminal (terminal No. 3) from ECM (terminal No. 77 - M/T) or PCM (terminal No. 51 - A/T) via the resistor in the ECM (M/T) or PCM (A/T). The fuel temperature sensor output voltage increases when resistance increases and decreases when resistance decreases. The ground terminal (terminal No. 2) is grounded to vehicle body. See Figure and Figure .
