    The Walker 242-1180 sensor for the 1996-1999 BMW 318ti 1.9L and other vehicles is an OE replacement that monitors engine vibration to detect knock (detonation), so the ECU can adjust ignition timing.

    • Resists heat, vibration and oil exposure in the engine block and cylinder head.
    • Installs into the original threaded mounting location with factory-style connectors, no modifications required.
    • Matches factory frequency response, sensitivity and electrical output for ECU integration.
    • Each Walker sensor is tuned to the resonant frequency of knock in its engine platform, so the ECU can retard spark when knock is detected.
    • Lets the ECU correct spark advance during knock conditions, which supports fuel efficiency, performance and emissions.

    Spark knock can lead to internal engine damage, reduced fuel economy and drivability issues. A fault code such as P0325 or P0330, or a timing problem, can be a reason to look at this sensor. Before you replace it, rule out damaged wiring and a loose connector, since a sensor-circuit code can come from more than the sensor itself.

    It is listed for a wide range of BMW models, led by the 1996-1998 BMW 318i 1.9L and the 1996-1998 BMW Z3 1.9L, with one sensor per car.
