P0182

Wiring Diagram:

CIRCUIT DESCRIPTION
The fuel temperature sensor is a thermistor that controls signal voltage to the Powertrain Control Module (PCM). When the fuel is cold, the sensor resistance is high, therefore the PCM will see high signal voltage. As fuel warms, sensor resistance becomes less and voltage drops. The fuel temperature sensor is integrated with the optical sensor. This is a type B DTC.

CONDITIONS FOR SETTING THE DTC
- Fuel temperature greater than 1O2°C (215°F).
- Conditions met for 2 seconds.

ACTION TAKEN WHEN THE DTC SETS
- Poor idle quality during hot conditions.

CONDITIONS FOR CLEARING THE MIL/DTC
- The PCM will turn the MIL off after three consecutive trips without a fault condition.
- A History DTC will clear when forty consecutive warm-up cycles that the diagnostic does not fail (coolant temperature has risen 5°C (40°F) from start up coolant temperature and engine coolant temperature exceeds 71°C (160°F) that same ignition cycle.

DIAGNOSTIC AIDS
A scan tool reads fuel temperature in degrees centigrade. After engine is started, the fuel temperature should rise steadily.

TEST DESCRIPTION
Number(s) below refer to the Step number(s) on the Diagnostic Table.

2. This Step determines if DTC P0182 is a hard failure or an intermittent condition.
3. This test will determine it signal circuit is shorted to ground.
