What voltage should a camshaft sensor be?
The reference voltage can be anything, but are usually either 5 or 12 volts. These digital sensors usually take the form of either a Hall Effect sensor or a magneto-resistive sensor.
How can the signal from a camshaft position sensor be measured?
NOTE: Better results usually are obtained by measuring the terminal “+” although the signal can be measured in the grounding circuit.
- Crank the engine with the starter.
- Plug in the inductive phase sensor or/and the onboard controller coupling.
- Connect a voltmeter between the signal and ground terminals of the sensor.
Can you Ohm a camshaft sensor?
Camshaft position sensor resistance test You can also measure your CMP sensor resistance. Look up the resistance value for your sensor in your vehicle repair manual. Set your multimeter to Ohms and touch your meter leads to the sensor terminal pins.
How do you check a cam and crank sensor signal by a PicoScope?
How to perform the test
- Use manufacturer’s data to identify the crankshaft and camshaft sensor signal circuits.
- Connect PicoScope Channel A to the crankshaft circuit.
- Connect PicoScope Channel B to the camshaft circuit.
- You will see that PicoScope has displayed an example waveform and is preset to capture your waveform.
How do you adjust a camshaft sensor?
How to Change a Camshaft Position Sensor
- Locate the camshaft sensor.
- Disconnect the electrical plug on the sensor by pressing on the tab and pulling it off.
- Insert the new cam sensor, making sure to keep the tip clean.
- Rotate the sensor to align the hole in the bracket with that of the mounting surface.
What type of signal does the camshaft position sensor produce?
Frequency varying

How do you test a camshaft sensor with a multimeter?
First, identify the power, ground, and signal wires using your vehicle repair manual. Next, test the sensor circuit by setting your multimeter to “DC volts.” Have your helper turn the ignition key on, but don’t start the engine. Touch the black probe on your meter to ground and the other probe to the power wire.
