4-18 FI SYSTEM
ENGINE COOLANT TEMPERATURE SENSOR (ECT SENSOR)
The engine coolant temperature sensor is installed at the ther-
mostat case.
The sensor detects the engine oil temperature in thermistor
resistance value, which is then converted to voltage signal and
sent to the ECM. The injection volume increases as oil tempera-
ture decreases.
The thermistor resistance value increases when the engine oil
temperature is low, and decreases when the engine oil tempera-
ture is high.
Thermistor
ATMOSPHERIC PRESSURE SENSOR (AP SENSOR)
The atmospheric pressure sensor is located under the seat.
The sensor detects the atmospheric pressure. The detected
pressure is converted into voltage signal and sent to the ECM.
The injection time (volume) is controlled according to the voltage
signal (output voltage).
The voltage signal increases as the atmospheric pressure rises.
