NTK Crankshaft Sensor (NTK 81136) CMC3-V137

This NTK Crankshaft Sensor (NTK 81136) CMC3-V137 - is an OEM-quality replacement part and is suitable for a range of vehicles.

In the highly-complex engine processes, the purpose of crankshaft and 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 - set using a crankshaft sensor, 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.
