SENSOR TESTS
Connect red meter lea d to terminal “A” and black
meter lead to terminal “C.” Rotate the sensor lever
through it s range of trave l. Resistance reading
must change evenly as the sensor lever is moved.
Connect red meter lead on terminal “B” and black
meter lea d to terminal “C.” Ro tate the sensor
lever. Resistance reading must chang e evenly as
the sensor lever is moved.
Engine Temperature Sensor Test
Remove the ele ctrical connector from the engine
temperature sensor.
Use a digital multimeter to measure sensor resis-
tance.
Air Temperature Sensor (AT) Test
Remove the electrical connector from the air tem-
perature sensor.
Use a digital multimeter to measure sensor re sis-
tance.
