Standard Ignition TH381 Throttle Position Sensor

Throttle Position Sensor for Ford and Lincoln

Standard Ignition TH381 is a throttle position sensor built for precise throttle angle feedback in a wide range of Ford, Lincoln, and Mercury applications. It uses an integrated circuit to read the rotation of a small magnet on the throttle shaft and delivers a calibrated linear output for consistent signal accuracy.

Key Features

• Integrated circuit design measures throttle shaft movement through a magnet-based sensing system
• Electronically calibrated output for voltage accuracy, linearity, and slope
• Custom elastomeric seal helps protect against dust, vapor, and liquids under the hood
• Female connector with 1 plug-in connection
• 4 male blade terminals for direct electrical connection
• Standard Ignition TH381 for service replacement applications

Detailed Description

The Standard Ignition TH381 throttle position sensor is engineered to provide accurate throttle angle input to the engine management system. In Ford F-150, Explorer, Mustang, Expedition, and related Lincoln and Mercury models, the sensor helps the powertrain control module monitor throttle movement for proper fuel and drivability control. The TH381 is calibrated during automated testing to lock in output voltage accuracy and linear response, supporting stable signal delivery across the throttle range. This part cross-references Walker Products 200-1335 and Focus Auto Parts 99074 for the same application.

What It Helps Solve

• Erratic throttle signal readings
• Hesitation or delayed throttle response
• Check engine light concerns related to throttle position input
• Rough idle or inconsistent acceleration
• Driveability issues caused by inaccurate throttle angle feedback

Installation Notes and Tips

Verify connector style and terminal layout before installation. This sensor uses a female plug-in connector with 4 male blade terminals, so the harness connection should match the OE configuration. Confirm vehicle application by year, make, and model before ordering. Fits 2004-2010 Ford Explorer, 2004-2010 Ford F-150, 2005-2012 Ford Mustang, and 2005-2014 Ford Expedition; also fits 2003-2006 Lincoln LS and 2004-2010 Mercury Mountaineer. Additional coverage includes 2005-2019 Ford E-350 Super Duty, 2010-2019 Ford Flex, and 2010-2017 Lincoln MKT.

Quality Assurance

Standard Ignition uses automated testing to verify output voltage accuracy, linearity, and slope before release. The sealed sensor design is intended to help maintain signal integrity in underhood environments where contamination and moisture are common.
