What is the position of camshaft?
Most early internal combustion engines used a cam-in-block layout (such as overhead valves), where the camshaft is located within the engine block near the bottom of the engine.
How do you check a crankshaft alignment?
Procedure: The crankcase alignment is checked using a dial gauge. The gauge is fitted between the adjacent webs, opposite the crankpin at half of the diameter from the shaft centre. The dial gauge measures the crank web spread at different angular position of the shaft.
What are the signs of a bad camshaft?
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.
How do I check my camshaft timing?
To confirm accuracy, you need a dial indicator with a measuring range of at least 1 inch on each lifter. With both valves closed, set the dial indicator at zero. Begin with the intake valve; slowly turn the crank clockwise until the lifter rises 0.050 inch. Stop turning the crank and read the degree wheel.
How does the crankshaft position and camshaft position sensor work?
The crankshaft position sensor (CKP) and the camshaft position sensor (CMP) work together to ensure that your engine runs smoothly. The CKP monitors the speed and position of the crankshaft, while the CMP monitors the speed and position of the camshaft (s). These two sensors each read an individual reluctor or tone ring.
When does a cam line up with the crankshaft?
When a cam is installed “straight-up,” the imaginary centerlines of the two shafts line up exactly. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline.
Where are the camshafts located on a car?
Depending on your vehicle, it can have a camshaft located inside of the block, which is known as an overhead valve engine, or it may have a camshaft located over the top of the cylinder head, which is known as an overhead cam engine. Your engine may have one, two, or even more camshafts, depending on its design.
Can a faulty camshaft position sensor cause high fuel consumption?
This is pretty rare when it comes to a faulty camshaft position sensor, but it is not impossible. If you experience a high fuel consumption you should absolutely check the trouble codes for any codes related to the camshaft position sensor. What is a Camshaft Position Sensor?
