What is the function of camshaft position sensor and crankshaft position sensor?

What is the function of camshaft position sensor and crankshaft position sensor?

The task of the camshaft sensor is to work with the crankshaft sensor to define the exact position of the crankshaft drive. Through the combination of both sensor signals, the engine control unit knows when the first cylinder is in the top dead point.

How does the camshaft and crankshaft position sensor work?

The camshaft and crankshaft position sensors monitor the location and speed of the camshaft and crankshaft. The camshaft position sensor monitors the rotation speed of the camshaft, which indicates valve position in the combustion cycle, while the crank position sensor monitors speed of crankshaft rotation, which gives piston location.

Why is my crankshaft position sensor not working?

If you can’t find anything wrong with the Crankshaft – Camshaft Position Sensor or its circuit; it’s possible you may have an intermittent failure or a failure in a related component. For example, you may have a weakened or overstretched timing belt or timing-belt tensioner.

Do you need a scope for a camshaft position sensor?

However, confirming the good or bad operation of a Crankshaft – Camshaft Position Sensor may require a scope. A failing sensor signal, for example, may be hard to check without special equipment. Still, You Can Do Some Simple Checks In Your Garage Using A Digital Multimeter (DMM) Tool.

How to tell the crankshaft position of a car?

Using your DVOM on the DC voltage setting, back probe the sensor wire. Attach the black multimeter cable to battery ground. Cranking the engine, you should see the voltage reading on the meter fluctuate. Note that a damaged or improperly aligned tone ring will also prevent proper sensor operation.

How much to replace a camshaft sensor?

Additional costs will be for the other engine parts that will support the camshaft and engine. A camshaft position sensor, which may be needed or replaced, can can cost $100 to $350 for the part.

What is the purpose of camshaft position sensor?

The camshaft position sensor is a crucial part of the engine management which ensures that the engine runs smoothly. The sensor is responsible for collecting information about the car’s camshaft speed and send it to the Engine Control Module (ECM).

What does a cam position sensor do?

The CAM sensor or camshaft position sensor’s role is to signal the ECM the camshaft position. The crank and cam sensor operates in sync with eachother. The CAM sensor is frequently used in determining which injector to fire in a sequential system and for the COP or coil on-plug ignition systems coil firing event.

How does camshaft sensor work?

The camshaft sensor keeps an eye on the exact position of the camshaft and then sends signals to the onboard computer system. The camshaft has a series of lobes that move up and down to open the intake and exhaust valves. These lobes are monitored by the camshaft sensor.
