Half the speed of the crankshaft, 2750 rpm.
An automotive engine's camshaft rotates at A. the same speed as the crankshaft. B. one-quarter the speed of the crankshaft. C. one-half the speed of the crankshaft. D. twice the speed of the crankshaft.
is the crankshaft position sensor the same and the engine speed sensor
That is the signal that you want the computer to start the engine by energizing the ignition circuit. FYI, On a OBD2 system, the ECM can detect a misfire in the firing order by looking at the increased speed of teeth passing the crank sensor. If the ECM doesn't detect a slight speed increase in the frequency of teeth passing the sensor, it knows that that cylinder didn't fire. In other words, it is looking for an increase in the crankshaft speed each time a cylinder fires.
The crankshaft and camshaft sensors monitor engine speed. When the sensors detect a change in speed, they attribute it to a misfire. Depending on the cylinder that was supposed to fire, the engine can determine when the change in speed took place and can single out a particular cylinder. When it happens with more than one cylinder, it becomes a mulit cyl misfire. This is one of the symptoms of a malfunctioning cam or crank sensor.
crankshaft rpm (revolutions per minute)
one half the speed of the crankshaft.
It's bolted to the bell housing on the upper passenger side near the firewall. It reads engine speed from the flywheel.
The camshaft operated the inlet and outlet valves in the cylinder to admit fuel to the engine before ignition and expel the exhaust gas after the power stroke. The camshaft operates at half the crankshaft speed in a four-stroke engine.
It is mounted just above the crankshaft pulley on the front of the engine.It is mounted just above the crankshaft pulley on the front of the engine.
