What to do if your camshaft sensor does not work?
When your camshaft position sensor has a poor circuit it may fail to work properly. Test the voltage of the circuit to ensure adequate connections and proper voltage. Finally, inspect the crankshaft position sensor and circuit as well.
How to test crankshaft and camshaft position sensors?
Here is how you can easily test both your crankshaft position sensor and camshaft position sensor. It’s very important to be able to test these sensor since because they control your ignition and fuel injector pulse and if they fail they could cause a Crank No start condition.
How is the camshaft position sensor connected to the ECU?
The wiring harness should be routed away from the high-tension cable to prevent interference. This procedure will determine if the Camshaft Position Sensor is able to send signal to the ECU. This is done by measuring the voltage across the signal and ground wires of the sensor.
When does the camshaft position sensor rise back to 12 volts?
It rises back to 12 volts when the pin leaves the sensor head. The Camshaft Position Sensor sends this signal to the PCM via the signal wire in the wiring harness (See Fig. 3).

How does the multimeter test the cam sensor?
CASE 1: The multimeter registered the On/Off 5 Volts DC as you turned the crankshaft pulley. This test result indicates that the camshaft position sensor is working fine. You have now eliminated the camshaft position (CMP) sensor as bad.
It rises back to 12 volts when the pin leaves the sensor head. The Camshaft Position Sensor sends this signal to the PCM via the signal wire in the wiring harness (See Fig. 3).
