What type of camshaft sensor is used to check voltage?
The two most common camshaft sensors you'll see are the magnetic and Hall-effect types. Both transmit a voltage signal to an electronic control module or to the car's computer. The magnetic type produces its own AC (alternate current) signal (a sine wave), and you can identify it by its two wires.
How to tell which cylinder is in power stroke?
To determine which cylinder is in its power stroke, your car's computer monitors the rotating position of the camshaft relative to the crankshaft position using a camshaft position (CMP) sensor. It uses this information to adjust the spark timing and the operation of the fuel injectors. Thus, the CMP sensor affects fuel economy, emissions control, and engine efficiency.
Why does my camshaft sensor fail?
Answer: Contamination from oil, moister or oil, vibration, can cause a camshaft sensor to fail prematurely. Check the mounting area for signs of contamination and make sure the unit is properly secure. Also, check for wiring damage. This may also cause a bad effect on the sensor itself.
Why does my CMP sensor stop working?
Just like every part or component in your car, the CMP sensor will eventually stop working when it's reached the end of its service life, because an internal part, wire, or related component has failed. The symptoms your engine may experience at this point can vary, depending on the type of sensor failure: for example, a problem in the circuit, the connector, the sensor itself, or a related component.
How to check if a sensor is bad?
Check for the presence of power flowing through the circuit. Touch one of your probes to ground (any metal part on the engine) and the other probe to each one of the sensor wires. If neither wire has current, there's a failure in the sensor's circuit.
How many camshafts are in an engine?
