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 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.
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.
In the case of a camshaft sensor failure, 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.
