A crank sensor (CKP) is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. The CKP sensor works in conjunction with a reluctor ring attached to the crankshaft. It tells the ECM where the crankshaft is at any given time. The ring moves in front of the sensor and generates a square wave voltage indicator that the ECM reads as the crankshaft position. The crankshaft position sensor (CKP) is an important component of the Electronic Injection System since it measures the rotation of the shaft where it is installed and informs the Control Unit (ECU). If the Sensor has problems the vehicle will not work. And what is the function of the CKP sensor? 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. If the ECU cannot detect a CKP signal, it will set a diagnostic trouble code (DTC), DTC P0335 - Crankshaft Position Sensor Circuit Malfunction, and illuminate the MIL or CEL (malfunction indicator lamp or check engine light). Without a CKP signal, you may experience no-start or start-stall conditions. Depending on year, make, and model, the kuN8iPy.
