Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Crankshaft sensor (Ver. 1): Notes
The crankshaft sensor is attached to the gearbox case.
The crankshaft sensor records the position of the crankshaft with the aid of an increment wheel screwed to the crankshaft. The engine control uses this to calculate the engine speed. The crankshaft sensor and camshaft sensor are necessary for the fully sequential fuel injection (fuel injection takes place individually for each cylinder at the specific ignition point).
The signal from the crankshaft sensor means that the engine control also evaluates the crankshaft acceleration. The crankshaft acceleration provides an indication of the combustion quality of individual cylinders.
