DTC P0182: Fuel Temperature Sensor "A" Circuit Low Input
- Perform test procedure. See TESTING PROCEDURE . Start engine. Using a scan tool, observe fuel temperature sensor signal. If fuel temperature sensor signal is greater than 302°F (150°C), go to next step. If fuel temperature sensor signal is not more than 302°F (150°C), circuit has returned to normal. Check for intermittent conditions. See INTERMITTENTS
in TROUBLE SHOOTING - NO CODES article. See ENGINE PERFORMANCE in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Clear memory and perform verification procedure. See CLEARING DIAGNOSTIC TROUBLE CODES and VERIFICATION PROCEDURE
.
- Turn ignition off. Remove fuel pump access cover located in right rear of trunk floor (sedan) or luggage compartment floor (wagon). On Forester, Impreza and Outback Sport, disconnect 6-pin fuel pump harness connector. See Fig 1 and Fig 2
. On Legacy and Outback, disconnect Gray 6-pin fuel pump harness connector. See Fig 3. Turn ignition on. Using a scan tool, observe fuel temperature sensor signal. If fuel temperature sensor signal is less than -40°F (-40°C), replace fuel temperature sensor. If fuel temperature sensor signal is not less than -40°F (-40°C), locate and repair short to ground in wiring between fuel pump and ECM. See ENGINE PERFORMANCE in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Clear memory and perform verification procedure. See CLEARING DIAGNOSTIC TROUBLE CODES and VERIFICATION PROCEDURE
