If your backup sensors aren't working:
* Check for obstructions: Something might be blocking the sensors (mud, snow, ice, a trailer hitch). Clean them carefully.
* Listen for a fault: Some Escape models emit a different tone or pattern of beeps to indicate a sensor fault. Consult your owner's manual for details on your specific model year.
* Check the fuse: A blown fuse could be the culprit. Your owner's manual will show you the fuse box location and diagram.
* Check the sensor wiring (advanced): If you have some automotive experience, you might inspect the wiring for damage, though this is generally not recommended unless you're comfortable with vehicle electronics.
* Take it to a mechanic or dealership: If none of the above resolves the issue, it's best to take your Escape to a qualified mechanic or Ford dealership for diagnosis and repair. They have the diagnostic tools to pinpoint the problem.
