DTC P0182: Fuel Temperature Sensor Circuit Low Input: Operation

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