  • Harness or connectors

    (The FTT sensor circuit is open or shorted)

  • FTT sensor
B) The comparison result of signals transmitted to ECM from each temperature sensor (IAT sensor, ECT sensor, EOT sensor, and FTT sensor) shows that the voltage signal of the FTT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state.
  • Harness or connectors

    (High or low resistance in the FTT sensor circuit)
