Vehicle does not drive like it used to. If your vehicle idles roughly, stalls frequently, has a drop-in engine power, stumbles frequently, has reduced gas mileage, or accelerates slowly, these are all signs your camshaft position sensor could be failing. Check Engine Light comes on. Vehicle will not start.
How does a cam work?
The key parts of any camshaft are the lobes. As the camshaft spins, the lobes open and close the intake and exhaust valves in time with the motion of the piston. It turns out that there is a direct relationship between the shape of the cam lobes and the way the engine performs in different speed ranges.

Double overhead cams control the opening and closing of a cylinder's valves. Valve timing gears on a four-cylinder engine the small gear is on the crankshaft, the larger gear is on the camshaft. The gear ratio causes the camshaft to run at half the RPM of the crankshaft. of car engines? Generally, engines with dual overhead camshafts (DOHC) are higher performance engines, they produce more power, and can run at higher speeds. The camshaft uses rotating lobes, called cams, that push against the valves to open them. The valve train is a collection of synchronised components responsible for optimising the timing and performance of the engine. Made up of numerous valves, rocker arms, pushrods, lifters and at least one camshaft, the valve train simultaneously regulates fuel intake, compression, ignition and waste expulsion by opening and closing a series of valves. Synchronised to the crankshaft by a chain, belt or gear array, the processes and timings overseen by the valve train speeds up or slows down accordingly in order to maximise performance and efficiency. Over time, the movements and consistency of the valve train can begin to slip as parts begin to wear away. Mistimed valve openings early, late, too short or long, can immediately affect a vehicle’s performance and potentially cause serious engine damage. Different engine configurations will use different valve trains.
