mance] A)
Rationally incorrect voltage from the
sensor is sent to ECM, compared with
the voltage signals from ECT sensor
and intake air temperature sensor. • Harness or connectors

• FTT sensor
• Combination meter
B) The comparison result of signals trans-
mitted 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 temper-
ature sensors when the engine is start-
ed with its cold state. • Harness or connectors
