mance]

The comparison result of signals transmitted 
to ECM from each temperature sensor (IAT 
sensor 1, IAT sensor 2, ECT sensor, FTT 
sensor, and EOT sensor) shows that the volt-
age signal of the IAT sensor 2 is higher/lower 
than that of other temperature sensors when 
the engine is started with its cold state.
