and Engine Coolant Temperature (ECT) sensor
The EOT sensor is a thermistor type sensor. The EOT
sensor is installed in the rear of the front cover, left of
the high-pressure oil pump assembly.
The ECT sensor is a thermistor type sensor. The
ECT sensor is installed in the water supply housing
(Freon® compressor bracket), left of the flat idler
pulley assembly, as viewed from the front of the
engine.
