BRAND NEW OEM Quality CRANKSHAFT POSITION SENSOR TO SUIT BMW'S VARIOUS VEHICLES
TO SUIT:
OEM# 13627548994, 12147503140, 12140148889
Package Includes:
1* 'OEM Quality' CRANKSHAFT POSITION SENSOR (3-PIN PLUG). D-shaped Connector.
The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines. It monitors the position and rotational speed of the crankshaft and sends the information to the engine control unit so it can make appropriate adjustments based on operating conditions. The crankshaft speed and position are some of the most important parameters used in engine management calculations, and many engines cannot run if the crankshaft position sensor is not providing an accurate signal.
Important! This sensor is a uniform 17mm OD along the entire sensor surface. However, some SMG transmissions("sequential manual gearbox", aka SMG-II / SMG2) use a sensor with a narrower sensor body. See BMW part #12142296184.
BMW does not make a distinction about which sensor is installed and you must check before ordering.
Unfortunately, this means removing the sensor, which will drain some fluid.

How do I test a crankshaft or camshaft position sensor?
Use an OBD2 scanner to check for fault codes P0335 to P0338 (crankshaft) or P0340 to P0349 (camshaft). You can also test the sensor with a multimeter - inductive sensors should show resistance between 200 and 1,000 ohms, while Hall effect sensors require a live voltage test with the engine cranking. Erratic or absent RPM signal on a live data scanner is a strong indicator of sensor failure.
Can a cam or crank sensor fault cause my vehicle to go into limp mode?
Yes. A faulty crankshaft position sensor in particular can cause the ECU to lose engine speed and position data entirely, which may trigger limp mode or prevent the engine from starting. A faulty camshaft sensor on variable valve timing engines can cause the VVT system to default to a fixed position, significantly reducing power and fuel economy.
Do cam and crank sensors need to be programmed after replacement?
In most cases no - aftermarket OEM replacement sensors are direct plug-in replacements that require no programming. However some vehicles, particularly late model European makes including BMW and Mercedes-Benz, may require a crankshaft adaptation reset using a dealer-level scan tool after replacement. Check your vehicle service information before replacing the sensor.
What are the symptoms of a faulty crankshaft position sensor?
Symptoms include intermittent stalling, engine not starting, rough idle, misfires, and a Check Engine light with codes P0335-P0338. In severe cases the engine will crank but not start as the ECU cannot determine crank position for ignition timing.
What are the symptoms of a faulty camshaft position sensor?
Symptoms include poor performance, misfires, difficulty starting, rough idle, and fault codes P0340-P0343. Variable valve timing systems (VVT) will also be affected, causing sluggish response and increased fuel consumption.
Can I drive with a bad crankshaft position sensor?
If the sensor has failed completely the engine will not start or will stall and not restart. If it is intermittently failing, driving is dangerous - the engine can cut out without warning. Replace it immediately.
Do I need to replace both the cam and crank sensor at the same time?
Not necessarily - replace whichever has failed based on fault codes and diagnosis. However, if your vehicle has high kilometres and one has failed, it is worth considering replacing both as they are similar in age and condition.
