- Engineered specifically for import vehicles
- Sealed connector that protects the electrical connection in harsh conditions
- Tested on vehicles for correct integration with electronic safety systems
Quick facts
- Part: Standard Ignition ALS1221 ABS wheel speed sensor
- Fits: 1995-2002 Isuzu Trooper and other vehicles
- Position: Front right
An ABS warning light, or an ABS that acts oddly under braking, can be a sign of a sensor problem. A lit light alone does not prove this sensor is at fault, since a damaged wire in the harness is another common cause. The front axle has one sensor on each side; this listing is the front right, and the front left is ordered separately.
Fits
This sensor is a direct-fit replacement for the 1995-2002 Isuzu Trooper, the 1999-2001 Isuzu Vehicross and the 1996-1999 Acura SLX, and it is tested on vehicles for proper fit.
