DTC P0183: Fuel Temperature Sensor Circuit High Input: Operation

A 5-volt voltage via the resistor in the ECM or PCM is applied to fuel temperature sensor output terminal (terminal No. 3) from the ECM (terminal No. 77 - M/T) or PCM (terminal No. 51 - 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 .
