DTC P0183-00: Fuel Temperature Sensor Circuit High Input: Notes

DTC P0183:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0183:00	Fuel temperature sensor circuit high 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 above 4.96 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 PCM connector or terminals malfunction Short to power supply in wiring harness between low fuel pressure sensor/fuel temperature sensor terminal E and PCM terminal 1AH Open circuit in wiring harness between the following terminals: Low fuel pressure sensor/fuel temperature sensor terminal E-PCM terminal 1AH Low fuel pressure sensor/fuel temperature sensor terminal C-PCM terminal 1CR Fuel temperature sensor malfunction PCM malfunction
