Installation Notes

Verify connector style, terminal count, and front right mounting location before installation. Inspect the linkage, wiring, and surrounding suspension components for corrosion or damage, since a failed sensor can be caused by exposure to road debris, water intrusion, or salt. After replacement, clear any stored fault codes and confirm the system levels correctly.
