Dorman Electronic Throttle Body for Ford/Lincoln 977-593 — OE FIX, Hall Effect Sensor & Aluminium Housing

The Dorman 977-593 Electronic Throttle Body is a direct-fit OE FIX replacement with a contactless Hall effect sensor and Sensor Shield seal to resist moisture and oil intrusion.

If your Ford or Lincoln has throttle response issues, rough idle, or a check-engine light related to the throttle body, this Dorman unit is engineered as a bolt-in replacement to restore proper electronic throttle control. Built as a 100% new aluminum assembly, it avoids the compromises of remanufactured units and adds updated internal protections designed to prevent the common failure modes found in original equipment throttle bodies.

How does this throttle body improve reliability compared to the original?

Dorman redesigned the internal components that commonly fail on OE throttle bodies. The critical upgrades include a non-contact Hall effect sensor that eliminates wear-prone contacts and a proprietary Sensor Shield butterfly shaft seal that helps block moisture and oil contamination.

• Contactless Hall effect sensor reduces internal electrical wear
• Sensor Shield seal defends against moisture and oil intrusion
• New 100% aluminum case — not remanufactured — for longer life
• Over one million cycle endurance testing for durability
