Subaru Legacy Crankshaft Position Sensor

The Crankshaft Position Sensor of the Subaru Legacy is applied by the engine control unit to keep track of the position and speed of the crankshaft. This information helps the engine control unit to time the fuel injection and ignition events accurately. Under normal functional conditions, the Crankshaft Position Sensor, in proximity to the teeth of a toothed wheel of the crankshaft or the flywheel, sends electrical pulses representing crank angle and speed. The information is applied by a Subaru Legacy powertrain control module to schedule fuel injection, set ignition timing, and coordinate other engine controls. In case of the Crankshaft Position Sensor losing signal, the engine may not start or stall, and drivability problems such as misfires, rough idle, or hesitation on acceleration may occur. Subaru designs the Legacy with Crankshaft Position Sensor specifications that follow the common types of inductive, Hall effect, magnetoresistive, and optical. Inductive units are passive. Hall effect and magnetoresistive have static nature. Optical versions give sharp edge detection but are more sensitive to fouling. Regardless of the style selected, Crankshaft Position Sensor is generally sealed against heat, vibration, corrosion, and fluid exposure to enable dependable starting and smooth operation of every Subaru Legacy.

Our website stands as the go-to online destination for OEM Subaru Legacy Crankshaft Position Sensor. With complete lines of genuine Subaru Legacy Crankshaft Position Sensor available at unbeatable market prices, we ensure top quality, reliability, and durability. Each part comes backed by the manufacturer's warranty, reinforcing your trust in our offerings.
