CRANKSHAFT POSITION SENSOR RESISTANCE
ENGINE COOLANT TEMPERATURE (ECT) SENSOR
For engine coolant temperature sensor location, see SYSTEM/COMPONENT TESTS article. Using ohmmeter, check resistance between electrical terminals on engine coolant temperature sensor. Ensure resistance is within specification in relation to specified temperature. (Scheme 1)
Scheme 1
HEATED OXYGEN SENSOR
For heated oxygen sensor application and sensor testing, see SYSTEM/COMPONENT TESTS article.
INTAKE AIR TEMPERATURE (IAT) SENSOR
For intake air temperature sensor testing, see SYSTEM/COMPONENT TESTS article. Using ohmmeter, check resistance between electrical terminals on intake air temperature sensor. Ensure resistance is within specification in relation to specified temperature. (Scheme 1)
MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR
For MAP sensor testing, see SYSTEM/COMPONENT TESTS article.
THROTTLE POSITION (TP) SENSOR
For terminal identification and testing procedures, see SYSTEM/COMPONENT TESTS article.
