Component Testing
- Connect the DMM from the KS signal circuit to the KS low reference circuit on the sensor side of the KS harness connector.
- Set the DMM to the 400 mV AC hertz scale and wait for the DMM to stabilize at 0 Hz.
- Tap on the engine block with a non-metallic object near the KS while observing the signal indicated on the DMM.
- The DMM should display a fluctuating frequency while tapping on the engine block.
IMPORTANT:
DO NOT tap on plastic engine components.
