    Sensor, crankshaft pulse

    The Sensor, crankshaft pulse (AS4122) provides critical crankshaft data for accurate engine timing. Replacing a faulty sensor restores smooth running, proper ignition, and reliable starting. Use Porza’s smart search to find the correct sensor.

    FAQ

    A crankshaft pulse sensor, also known as a crankshaft position sensor, detects the position and rotational speed of the crankshaft. Its function is to send this data to the engine control unit (ECU) for accurate ignition timing and fuel injection.

    Key specifications include sensor type (inductive or Hall effect), connector type, number of pins, mounting design, and compatibility with the vehicle. It must provide precise and reliable signal output under engine conditions.

    Replacement is necessary when the sensor fails or gives incorrect readings. Common symptoms include engine stalling, difficulty starting, misfires, or warning lights.

    Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.

    Porza provides high-quality engine management components with fast delivery across Europe and options for online ordering or in-store pickup.

    If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
