P0110 IAT SENSOR
P0110 IAT SENSOR
DescriptionINFOID:0000000001162577
The intake air temperature sensor is built into mass air flow sensor. The sensor detects intake air temperature
and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical
resistance of the thermistor decreases in response to the temperature rise.

P0115 ECT SENSOR
DescriptionINFOID:0000000001162581
The engine coolant temperature sensor is used to detect the engine coolant temperature. The sensor modifies
a voltage signal from the ECM. The modified signal returns to the ECM as the engine coolant temperature
input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance
of the thermistor decreases as temperature increases.
