Standard Ignition ALS2166 front right ABS wheel speed sensor for the 2002-2006 Infiniti Q45 and other vehicles senses how fast the wheel turns and sends that signal to the ABS. The ABS uses it to monitor each wheel.
An ABS warning light that stays on can mean a wheel speed sensor has failed. Before you replace this sensor, rule out a damaged harness or a loose connector, since either one can also set off that light.
This sensor fits the 2002-2006 Infiniti Q45 and the 2003-2004 Infiniti M45.
