Sensor and Circuit Tests

Engine Temperature Sensor Test

Remove the electrical connector from the engine
temperature sensor.
Use a digital multimeter with appropriate test
probe leads to measure sensor resistance.
Engine Temperature Sensor Resistance
680 Ω ± 5% @ 212°F (100°C)
10000 Ω ± 1% @ 77°F (25°C)
32654 Ω ± 2.5% @ 32°F (0°C)

Engine Temperature Circuit Test

Remove the electrical connector from the engine
temperature sensor.
Use a digital multimeter with appropriate test
probe leads to measure sensor circuit resistance.
Make sure the key switch is in the OFF position.
Connect the positive meter lead to the engine har-
ness connector wire listed in the table. Connect
the negative meter lead to engine ground.

Exhaust Temperature Sensor
(EGT) Test
Remove the electrical connector from the air tem-
perature sensor.
Use a digital multimeter with appropriate test
probe leads to measure sensor resistance.

Exhaust Temperature Circuit
(EGT) Test
Remove the electrical connector from the exhaust
temperature sensor.
Use a digital multimeter with appropriate test
probe leads to measure sensor circuit resistance.
Make sure the key switch is in the OFF position.
Connect the positive meter lead to the engine har-
ness connector wire listed in the table. Connect
the negative meter lead to engine ground.
