Crankshaft Position Sensor: Testing and Inspection
Engine Speed Sensor
Disconnect the engine speed sensor electrical connector from the wiring harness. Check the resistance of the sensor by placing an ohmeter across
terminals A and B (marked on sensor connector). With the engine at normal operating temperature, the ohmeter should read 200 ± 75 ohms. Replace
sensor if ohmeter readings are not within specifications.
