Walker Products Engine Crankshaft Position Sensor P/N:235-91139
Walker Products 235-1478 crankshaft position sensor for the 1994-1995 Mercedes-Benz E320 6-cylinder 3.2L and other vehicles reports crankshaft speed and position to the engine control module. The module uses that data for ignition timing and fuel injection, and you may also hear this part called a crank sensor.
A worn crankshaft position sensor can show up as hard starting, stalling or a misfire. These signs alone do not prove the sensor is at fault, since a damaged wiring connector is another common cause.
This crankshaft position sensor is listed for a wide range of Mercedes-Benz models, led by the 1994-1995 Mercedes-Benz S420 V8 4.2L and the 1994-1995 Mercedes-Benz S500 V8 5.0L. The listing is one sensor, and each engine takes a single one. If your Mercedes-Benz is not named here, look up your own year and engine in the "Vehicles it fits" section.
