What does the engine speed sensor do?
The engine speed sensor (or crankshaft sensor / crank angle senor) is used to detect how quickly your engine’s crankshaft is spinning. It then sends this data to your car’s onboard computer, which makes adjustments to your engine’s ignition timing and fuel injection to allow for optimum engine fuel economy, engine power, and exhaust emission conditions.
The engine speed sensor is mounted near to the engine’s crankshaft. Most engine speed sensors create a small magnetic field. When the crankshaft spins, its serrated edges obstruct the magnetic field. The frequency of obstructions determines how fast the crankshaft is moving.
As well as an engine speed sensor, most cars with auto transmissions will also have a transmission speed sensor, which monitors the rotations of your car’s transmission to change gears.
Problems with the engine speed sensor can affect the air/fuel ratio inside your engine. This can affect the performance and efficiency of the engine.
