P0197, P0198 EOT SENSOR
P0197, P0198 EOT SENSOR
Description
INFOID:0000000009719991
The engine oil temperature sensor is used to detect the engine oil
temperature. The sensor modifies a voltage signal from the ECM.
The modified signal returns to the ECM as the engine oil tempera-
ture input. The sensor uses a thermistor which is sensitive to the
change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.
<Reference data>
*: These data are reference values and are measured between ECM terminals 54
(Engine oil temperature sensor) and 52 (Sensor ground).
