DTC P0182-00: Fuel Temperature Sensor Circuit Low Input: Notes

DTC P0182:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0182:00	Fuel temperature sensor circuit low input
DETECTION CONDITION	The PCM monitors the fuel temperature sensor signal. If the PCM detects that the fuel temperature sensor voltage at the PCM terminal 1AH is below 0.042 V for 5 s, the PCM determines that the fuel temperature sensor circuit has a malfunction. MONITORING CONDITIONS Battery voltage: 8 V or more Diagnostic support note This is a continuous monitor (CCM). The check engine light does not illuminate. FREEZE FRAME DATA is not available. Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Not applicable
POSSIBLE CAUSE	Low fuel pressure sensor/fuel temperature sensor connector or terminals malfunction Fuel temperature sensor malfunction Short to ground in wiring harness between low fuel pressure sensor/fuel temperature sensor terminal E and PCM terminal 1AH PCM connector or terminals malfunction Fuel temperature sensor signal circuit and ground circuit are shorted to each other PCM malfunction
