CIRCUIT DESCRIPTION
The fuel temperature sensor is a thermistor which controls the signal voltage to the PCM. When the fuel is cold, the sensor resistance is high, therefore the PCM will see a high signal voltage. As the fuel warms, the sensor resistance becomes less and the voltage drops. The fuel temperature sensor is integrated with the optical sensor. This is a type B DTC.
CONDITIONS FOR SETTING THE DTC
^ The fuel temperature is greater than 102°C (215°F).
^ The conditions were 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 Malfunction Indicator Lamp (MIL) oft after three consecutive trips without a fault condition.
^ A History DTC will clear after forty consecutive warm-up cycles during which the diagnostic does not fail (coolant temperature has risen 5°C (40°F) from the start up coolant temperature and the engine coolant temperature exceeds 71°C (160°F) during that same ignition cycle).
^ Use of a Scan Tool will clear the DTC codes.
DIAGNOSTIC AIDS
A scan tool reads the fuel temperature in degrees centigrade.
An intermittent may be caused by the following:
^ Poor connections.
^ A rubbed through wire insulation A broken wire inside the insulation.
TEST DESCRIPTION
The 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 if signal circuit is shorted to ground.
