Detailed Description

HELLA 230040421 is an ABS wheel speed sensor engineered to monitor wheel movement and send the signal needed for ABS operation. Accurate wheel speed input helps the braking system respond correctly during stops, especially on vehicles where the sensor is mounted at the front axle wheel side. The included harness and 2-pin female connector simplify replacement on supported applications, while the standard replacement construction is built for everyday road use. This part cross-references Standard Ignition ALS1465 and NTK AB1994 for the same application.
