Crankshaft position sensors

Crankshaft position sensors

A crankshaft position sensor gives the control unit information about the rotational speed and position of the shaft. On this basis the control unit determines the moment of ignition and fuel injection, so its proper function is essential for correct engine operation. In this category you will find sensors for petrol and diesel engines of various makes.

A faulty sensor can cause problems starting the engine, stalling while driving, jerking and the check engine light coming on. Before buying, it is worth reading the fault codes with a diagnostic computer. When selecting, check the make, model, year, engine code and the part's catalog number.

Sensors differ in type (inductive, Hall effect), shape and connector, so exact fit is key. When fitting, make sure the socket is clean and the gap to the toothed wheel is correct. After replacement, clear the stored fault codes and check the engine operation.
