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.
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.
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.
Why is there no spark from the ignition coil?
Its like the ignition coil is not collapsing to send the spark energy to the spark plugs. How can you check the pickup coil to see if the timing events are happening in order to make and break the ground on the ignition coil in order to induce a spark on the secondary side, so that spark energy is sent to the spark plugs?
Can a crank and cam sensor be replaced?
I replaced both the cam and crank sensor and car still will not start but if I unplug the crank sensor it starts up and runs like crap. I can not figure out what to do next. My car has 91000 miles. My car has an automatic transmission. You should check to see if your vehicle has jumped timing.
How does a crankshaft camshaft position sensor work?
Since this type of Sensor only has two wires and no Power Supply, testing them is not that hard: One of the two wires is the Signal wire. Consequently, Sending the Signal to the Fuel Injection Computer or Ignition Module. The other wire acts as a Ground return.
Why is my crank and cam sensor not working?
If it is giving a signal, then the cam and crank signals are way off and causing the wrong ignition timing. If you need to have a local expert come check this problem for you, a certified technician from YourMechanic can come to your car’s location to diagnose the hard starting issue and pinpoint the correct fix.
What’s the difference between a camshaft and crankshaft position sensor?
A lot of people confuse the camshaft position sensor with the crankshaft position sensor because they sound similar. But there’s a big difference between the two as they perform different functions in the vehicle and have different symptoms when something goes wrong with them.
What are the symptoms of a bad camshaft sensor?
7 Symptoms of a Bad Camshaft Position Sensor (and Replacement Cost) 1 Check Engine Light Illuminates. 2 Ignition Problems. 3 Car Jerking or Surging. 4 Engine Stalling. 5 Poor Acceleration. 6 Problems Shifting. 7 Bad Fuel Mileage.
