• Replacement of a worn or failed OE-style speed sensor

Installation Notes and Tips

Verify connector style, terminal count, and mount type before installation. This sensor uses a bolt mount with one bolt hole and a female connector, so matching the original electrical and physical configuration is important. Confirm vehicle build timing for 2000 Nissan Quest models, since fitment is listed separately for units built from 06/2000 and to 06/2000.

For best results, inspect the harness connector and surrounding wiring before installing Walker 240-1043. Because the wiring harness is not included, reuse the existing harness connection if it is in good condition.
