TYPICAL FUEL TEMPERATURE SENSOR CIRCUIT CHECK MALFUNCTION THRESHOLDS
| P0180
: if after a 6 hour engine off soak, the difference in temperature between the fuel temperature sensor and the ECU temperature sensor exceeds 20C, a DTC is set (3.2L only) P0181 : If after an 6 hour engine off soak, the difference in temperature between the fuel temperature sensor and the charge air cooler outlet temperature sensor exceeds 40 deg C or if the difference in temperature between the fuel temperature sensor and the charge air cooler outlet temperature sensor exceeds 20 deg C and no active block heater is detected, a DTC is set (6.7L only) P0182, P0183 : FTS voltage < 0.0946 V (0.122.4 V = 150 deg C) or > 4.918 V (4.762 V = -40 deg C) |
