Description:

  • Fuel temperature detected is out of expected range

Possible Symptoms:

  • Experience a loss of power.

  • Engine may stall while driving

  • The engine oil will exhibit dilution

Possible Causes:

  • Faulty Engine Fuel Temperature Sensor

  • Engine Fuel Temperature Sensor harness is open or shorted

  • Engine Fuel Temperature Sensor circuit poor electrical connection

Related Parts:

  • Fuel Temperature Sensor: The fuel temperature sensor measures the temperature of the fuel in the fuel injector. Problems with this sensor lead to engine misfire, engine stalling

Possible Solutions:

  • Check for voltage at each fuel injector

  • If the crankshaft position sensor is not damaged, perform a test on the ignition switch and lock cylinder using the manufacturer's recommended procedure. If any issues are found during this test, the ignition switch or lock cylinder can be replaced

  • If no issues were found with the ignition switch or lock cylinder, test the engine shutoff solenoid for proper function.

  • As long as no issues are found with the operation of the cooling fan, the mechanic would then use an infrared thermometer to check the cooling system for hot spots
