Installation Notes and Tips

Verify connector style, terminal count, and mount type before installation. This sensor uses a female connector, 2 terminals, and a bolt mount, so matching the original configuration is important for proper fitment. Confirm the application by year and model: Fits 1997-2003 Ford Escort, N/A; Fits 1997-1999 Mercury Tracer, N/A.
