Standard Ignition ABS Wheel Speed Sensor P/N:ALS451
Keep the anti-lock braking and traction-control systems reading wheel rotation accurately with the Standard Ignition ABS Wheel Speed Sensor ALS249. It installs as a direct-fit replacement at the front right wheel of the 2002-2004 Nissan Frontier, restoring the signal the ABS control module relies on.
An ABS wheel speed sensor monitors how fast its wheel is turning and reports that data to the ABS/traction-control module, which uses it to modulate braking and prevent wheel lock-up.
Signs this sensor may need replacing include an illuminated ABS or traction-control warning light and related trouble codes. Because those symptoms can have other causes, diagnose the fault before replacing; if a failed front right wheel speed sensor is the cause, this ALS249 replaces it.
Fitment: 2002-2004 Nissan Frontier (front right).
