What is the role of the Crankshaft Position Sensor and Speed Sensor on the BMW M3?

The Crankshaft Position (CKP) sensor/engine speed sensor provides the Engine Control Module (ECM) unit with engine speed information. The sensor reads the information from a tool hed wheel mounted on or integral with the crankshaft. The S14 engines' speed sensor is mounted next to the cylinder identifying sensor on the bell housing and uses the teeth of the flywheel's ring gear for calculating the engine speed. The M20, M42, M50 and S50 engines up to and including 1995 vehicles (OBD I) have the CKP sensor/speed sensor mounted on the front engine cover and reads a toothed wheel mounted to the crankshaft pulley. On all 1996-98 models (OBD II compliant), the CKP sensor is mounted into the lower left rear portion of the engine block and reads a tool hed wheel mounted to the end of the crankshaft assembly. If the Engine Control Module (ECM) does not receive a signal from the Crankshaft Position (CKP) when the engine is cranked, the engine will not start. Use a BMW service tester, the OBD I blink code or on OBD II vehicles, use a suitable Data Scan Tool (DST) to check for faults or if capable, to read the values of the components. If this diagnostic equipmenl is not available, proceed as follows. The engine speed sensor provides the DME unit with engine speed information. The sensor reads the information from a tooth wheel mounted on the crankshaft hub except on the S14 engine. It can also be called the crankshaft sensor. The S14 engines speed sensor is mounted next to the cylinder identifying sensor and is removed in the same manner as the cylinder identifying sensor. The sensor on the S14 engine connects to a plug mounted in a group of 3 plugs on the engine compartment rear wall, next to the engine harness connector and diagnostic socket. It is the connector on the right side. Turn the ignition switch to the OFF position. Trace the sensor lead back to the connector and disconnect. Check the resistance between terminals 1 and 2. The resistance should be 49G-590 ohms. On front mounted Crankshaft Position (CKP) sensors, detach the CKP sensor connector. Use a digital ohmmeter and measure the resistance between the two outer terminals of the sensor. The measured resistance should be 1.150-1,400 ohms.

BMW M3 Speed Sensor

The BMW M3 Speed Sensor plays a central role in converting wheel or output shaft rotation into electronic signals that direct changing shifting, traction, and braking strategies. Each Speed Sensor on a modern BMW platform relies on a ferromagnetic toothed ring to pass a passive or active pickup. The resulting oscillating or conditioned signal travels to the powertrain computer so it can time gear changes, set line pressure, and control torque converter lockup. Early BMW models applied a Speed Sensor that was mounted on the transmission and output a simple magnetic waveform, while later M3 versions and the current M3 line feature Speed Sensor units on every hub outputting precise data to the ABS. The Speed Sensor is concerned with the speed of the road in general, while a Speed Sensor measures each wheel individually, allowing the module to compare rates and respond to slip. Active sensors have the advantage over passive sensors in that they have electronics built into the sensor that cleans up the signal, is tolerant of larger air gaps, and is accurate at very low rpm. Whether passive or active, every BMW M3 relies on the impeccable data from Speed Sensors to ensure that shifts stay crisp and stopping distances remain short.

If you are looking for OEM BMW M3 Speed Sensor, we highly recommend to shop with us. Not only do we offer budget friendly prices, but we also provide fast delivery. In addition, we have a hassle-free return policy on all genuine BMW M3 Speed Sensor that come backed by the manufacturer's warranty.
