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

The Dorman 977-593 Electronic Throttle Body is a direct-fit replacement that restores throttle control with a contactless Hall effect sensor and a sealed butterfly shaft to resist moisture and oil intrusion.

If your Ford or Lincoln vehicle shows erratic idle, reduced throttle response, or a check engine light linked to the throttle control module, this OE FIX unit is built to address the common failure points of original equipment throttle bodies. Dorman engineered this part as a 100% new aluminum assembly with upgraded electronics and sealing to improve long-term reliability without requiring a remanufactured core return.

How does this throttle body prevent the failures I see on older units?

Rather than relying on contact-based sensing that can wear or corrode, Dorman uses a non-contact Hall effect sensor which resists electrical degradation from contaminants. The Sensor Shield butterfly shaft seal blocks moisture and oil from entering the internal electronics where most failures originate.

• Contactless Hall effect sensing for consistent position feedback
• Proprietary Sensor Shield sealing to keep contaminants away from electronics
• New aluminum housing—no remanufactured parts or core charge

Will this part fit my Ford or Lincoln vehicle and how do I confirm compatibility?

This Dorman throttle body is designed to fit specific Ford and Lincoln models across listed years, but exact fitment depends on engine and trim. Use the vehicle garage/tool on the product page to enter your make, model and trim so you can confirm fit before ordering. Installation is plug-and-play for compatible applications, matching original harness and mounting points.

• Check fitment using the make, model, and trim input on the product page
• Plug-and-play electrical connector and bolt pattern for direct replacement
• Compatible with many 2011–2020 F-150, Transit, Expedition, and Navigator configurations

What durability and testing standards back this replacement part?

Dorman builds this throttle body as a new unit and subjects it to durability and regulatory testing to confirm long-term operation. The assembly meets Federal Motor Vehicle Safety Standards and passes endurance tests exceeding one million cycles, demonstrating resistance to wear in normal operating conditions.

• 100% new case aluminum construction for strength and corrosion resistance
• Endurance-proven with more than 1,000,000 cycle tests
• FMVSS-compliant evaluation and vehicle try-on testing for fit and function

How easy is installation and what should I expect during replacement?

For most technicians and experienced DIYers, replacing this throttle body is straightforward because it follows OEM mounting and connector layouts. You should disconnect the battery, remove intake components for access, swap the throttle body, and follow any manufacturer-specific relearn or calibration steps after installation.

• Disconnect battery and relieve intake for safe removal
• Swap unit, reconnect wiring harness and vacuum lines as applicable
• Perform any ECU relearn or idle adaptation per vehicle service instructions

Who this is for: The Dorman 977-593 OE FIX throttle body is intended for owners and technicians working on compatible Ford and Lincoln vehicles—especially those experiencing throttle response problems, intermittent check engine lights, or prior throttle body failures due to contaminated electronics. It suits anyone who wants a brand-new, tested replacement that focuses on improved sealing and non-contact sensing over remanufactured options.

Compatible vehicles include select Ford Expedition (2015–2017), Ford F-150 (2011–2016), Ford Transit series (2015–2020 for 150/250/350/350 HD), and Lincoln Navigator (2015–2017). Always verify fit with your exact trim and engine via the fitment tool before purchasing to ensure a correct, hassle-free replacement.
