Many people believe that a car can’t run without a camshaft position sensor. After all, this is the part of the engine that controls the valves, and without it, the engine would not be able to properly function. However, this is not always the case. In fact, some cars actually do run without a camshaft position sensor. So what does this mean for you?
What is a Camshaft Position Sensor?
A camshaft position sensor (CPS) is a device that monitors the position of the camshafts in an engine. This ensures that the valves are open at the correct time, which allows the engine to run correctly. If the CPS malfunctions, it can cause the engine to run poorly or not at all.
What are the Symptoms of a Car Running without a Camshaft Position Sensor?
A car running without a camshaft position sensor can be a sign that there is something wrong with the engine. The sensor helps the engine know where to find the camshafts, and without it, the engine may not be able to function properly. Some of the common symptoms of a car running without a camshaft position sensor are that it may not start, or it may have poor performance. If you notice one of these signs in your car, it’s best to get it checked out by a mechanic.
How to Test for a Camshaft Position Sensor
If your car is not starting, there is a very good chance that the camshaft position sensor is malfunctioning. A camshaft position sensor monitors the rotation of the camshafts and relays this information to the computer. When the sensor malfunctions, the computer cannot correctly track engine rotations and therefore does not know how to properly fuel the engine.
To test for a camshaft position sensor, you will need:
-A voltmeter
-A battery
-A spark gap tester
-A set of jumper cables
-A car
-A wrench
To test a blown fuse, remove the negative battery cable then disconnect all other electrical connections in the car. Disconnect the spark plug wires at both ends. Turn on the ignition and jump start the car. If everything works OK then your problem was probably a blown fuse. If not, it’s most likely a broken or malfunctioning camshaft position sensor.
How to Replace a Camshaft Position Sensor
If your car doesn’t start, there’s a good chance the camshaft position sensor is malfunctioning. This sensor helps the engine know where to go and when to start.
Replacing the camshaft position sensor is a relatively simple job, and can be done in just a few hours with a few basic tools and supplies. Follow these steps to replace the sensor:
1. Remove the wheel and tire. This will give you better access to the underside of the car.
2. Locate the timing belt cover on the engine block. It should have screws around it that you can remove. Once it’s free, use a wrench to unscrew the cover.
3. Find the camshaft position sensor on top of the engine block. It’s going to have wires attached to it, so be careful not to lose them or pull them out of their harnesses.
4. Disconnect both wires from the sensor and wrap them around your fingers several times, making sure they’re secure. Then, screw the cover back onto the engine block and reattach the timing belt cover screws.
5. Reinstall the wheel and tire and you’re ready
Conclusion
I hope that this article on car engines has helped explain what a camshaft position sensor is and why it is important. A malfunctioning camshaft position sensor can cause a number of problems with your car, including reduced engine performance, difficulty starting the car, and more serious issues like loss of power and even stall out.
