What happens if the camshaft position sensor is not working?
In such a case, the computer would calculate the need for spark advance (when the spark plug fires sooner in the compression stroke than otherwise) to be almost maximum. But if the camshaft position sensor is not working, the car’s computer cannot know when to fire the ignition coils to achieve the desired advance.
Can a camshaft sensor cause a car not to have spark?
The advantages to such a system include the absence of a rotor or distributor cap, which may burn or crack with use, along with the absence of a vacuum advance diaphragm, which can rupture or leak. But when a camshaft position sensor takes the place of a distributor, failure of that sensor could result in there being no spark.
How to know if your engine has no spark?
First Confirm Your Engine Has No Spark. 1 Disable the fuel system by removing the fuel pump fuse or relay. 2 Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. 3 Finally, Have someone crank the engine and watch for spark.
