How To Test Crankshaft Position Sensor Bosch Inductive Speed Sensor This test shows how to test a crankshaft position sensor using a simple multimeter. readings and pin designations may vary with manufacturer.follow us face. An inductive ckp sensor consists of a circuit with a wire coiled around a magnet. the sensor is accompanied by a pulse wheel, typically arranged about the flywheel circumference. the pulse wheel passes through and disturbs the sensor magnetic field inducing a circuit voltage. the induced voltage depends on engine speed: the faster the pulse.
Crankshaft Position Sensor Ckp Working Types Symptoms 43 Off How to test crankshaft position sensors without any guess work using multiple methods and tools to obtain and analyze sensor signals. these proven methods ca. A ckp sensor provides an engine control module (ecm) with its primary engine timing reference signal. the ecm uses it to calculate the engine speed and position for accurate injection and ignition control. the signal is also used to detect engine speed anomalies from misfires etc. an inductive ckp sensor consists of a circuit with a wire coiled. Some of their more common locations are: in the distributors. on timing covers. behind timing covers. on the engine blocks themselves. in this type of setup, the sensor goes thru' the block to reach its toothed disc. examples of this are the gm 3.1 and 3.4l v6 engines. on transmission bell housings. Alldata says that the ckp sensor determins timing for fuel injector and ignition of each cylinder and also detects engine speed. it should also trigger code 4. so according to that, the engine must be running for it to be accurate. it should have 350 700 ohms of resistance between sensor terminal and ecm terminal.
