ENGINE TEMPERATURE SENSOR
1. Measure:
• Engine temperature sensor resistance
(at the specified temperature)
Out of specification → Replace.
Engine temperature sensor
resistance:
20 °C (68 °F): 54.2–69.0 kΩ
100 °C (212 °F): 3.12–3.48 kΩ
Measurement steps:
• Suspend the engine temperature sensor
in a container filled with water.
• Slowly heat the water.
• Measure the resistance when the speci-
fied temperature is reached.
INTAKE AIR TEMPERATURE SENSOR
1. Measure:
• Intake air temperature sensor resistance
(at the specified temperature)
Out of specification → Replace.
Intake air temperature sensor
resistance:
0 °C (32 °F): 5.4–6.6 kΩ
80 °C (176 °F): 0.29–0.39 kΩ
Measurement steps:
• Suspend the intake air temperature sen-
sor in a container filled with water.
• Slowly heat the water.
• Measure the resistance when the speci-
fied temperature is reached.
