Part Finder Countries EMEA Camshaft & Crankshaft Sensors Because Timing is Everything Timing is a key factor when it comes to keeping an internal combustion engine running properly. In the highly complex engine processes, the purpose of camshaft and crankshaft sensors is to provide the engine’s ECU with the most essential information needed to run the engine. Consequently, exact timing of fuel injection and ignition is essential for smooth and efficient engine operation. 200 plus part numbers Wide market coverage Double-sided label for quick and easy selection Clear user installation sheet and securely sealed bag How camshaft & crankshaft sensors work Connected to the pistons and, via flywheel and clutch, to the gearbox, the crankshaft converts the linear up and down movements of the pistons to rotary motion. This turning of the crankshaft is what powers the engine and makes the vehicle move. The crankshaft sensor keeps track of this rotational speed as well as the crankshaft position. The camshaft, driven by a timing belt or chain by the crankshaft, rotating with half of the crankshaft’s speed, opens and closes the valves. Installed nearby, the camshaft sensor is responsible for measuring the position of the camshaft. This signal, in conjunction with the crankshaft position, is used to determine which cylinder is currently in its power stroke. The ECU needs this signal to determine when to inject fuel and to operate the spark plug. Consequences of Camshaft & Crankshaft Sensor Failures The crankshaft sensor delivers the main input signal for the ECU. Unlike many other sensors, where, in case of a failure, the ECU can calculate a default value and keep the engine running, this is not the case for the signal of the engine speed sensor. Without this signal, the ECU cannot keep the engine running, resulting in a car breakdown. In the case of a camshaft sensor failure, the consequences are less severe, but drivers may experience delayed starting. In addition, if the engine is equipped with variable valve timing, it will be disturbed as well, as the camshaft sensor signal is used to monitor this function. The engine will keep running, but with reduced power and performance. Sensors don’t have dedicated exchange intervals. Water in the connector or sensor, broken wires and age are factors that may contribute to the failure of engine speed and position sensors. To prevent these parts from becoming faulty, it is highly advisable to replace them during the lifetime of your vehicle.
