It is the sensor that reports the position of the eccentric shaft in BMW's Valvetronic variable valve lift system. The supplier lists it for BMW 1 Series, 3 Series, X1, X3 and Z4 models. Easy Life Markets sells it as a single, new replacement sensor for owners and workshops fixing Valvetronic faults.\u003c\/p\u003e\n\n\u003cp\u003eThe original supplier title called this a \"crankshaft phase eccentric shaft sensor\". It does not read the crankshaft. It reads the eccentric shaft in the cylinder head, so we have named it clearly as an eccentric shaft sensor to avoid confusion with a crankshaft position sensor.\u003c\/p\u003e\n\n\u003ch2\u003eWhat the Eccentric Shaft Sensor Does\u003c\/h2\u003e\n\u003cp\u003eOn BMW engines with Valvetronic, engine power is controlled mainly by changing how far the intake valves open, instead of relying only on a throttle plate. An electric motor turns an eccentric shaft in the cylinder head to change the intake valve lift. The eccentric shaft sensor tells the engine computer the exact angle of that shaft, so the computer can set the correct valve lift for the throttle position.

If you find oil around the sensor, replace the valve cover gasket at the same time, clean the connector thoroughly, and check that the wiring is dry.
