What Is CKP count?
The ECM uses signal pulses from the crank position sensor (CKP) to calculate when a particular cylinder is approaching top dead center. The pulses from the cam position sensor (CMP) are used to decide whether it is on a compression or an exhaust stroke.
What to do if your crankshaft is out of sync?
The ignition timing can be compensated for by simply rotating the distributor as the chain and gears wear…Even with the cam timing retarded, these engines seldom have any drivability problems…
Why are the timing marks on my camshaft out of sync?
The cam and crank sensors must be synced exactly. It doesn’t matter if the belt is made of rubber. It’s a reinforced rubber belt so it can’t stretch to compensate for the mistiming. This shows how the timing marks must align exactly when installing the timing belt on your engine. http://www.ricekiller.com/forums/thread76681.html
Can a single crank sensor diagnose a cam problem?
So if you have a cam timing problem, you could also do this with one single cam sensor and a single crank sensor. But if you have some sort of timing issue that you want to look at, check the correlation between them and that should help you diagnose it.
How many degrees can a camshaft be out of sync?
And the car can tolerate up to 12degrees differences in camshaft and crankshaft sensor. I’ve seen old timing chain engines with the chain worn badly enough that the cam timing is retarded 5-10 degrees.

Can a timing belt be used instead of a chain?
Timing belts are not that common. You’re much more likely to find a timing chain in cars and trucks than belts. Smaller cars, particularly Japanese made ones, can use timing belts instead of a timing chain. They are most commonly found on four cylinder engines.
