Standard Ignition TH394 Throttle Position Sensor

Throttle Position Sensor for Ford Super Duty Applications

Standard Ignition TH394 is a throttle position sensor built for precise throttle input feedback on select Ford trucks and vans. It is engineered with a fixed installed output to match OE calibration, helping maintain consistent signal response for the engine control system.

Compatible With 2004 Ford E-350 Club Wagon, 2004 Ford E-350 Super Duty, 2004 Ford Excursion, 2004 Ford F-250 Super Duty, 2004 Ford F-350 Super Duty, and 2005 Ford Excursion.

Key Features

• Female connector with 1 plug-in connection
• 6 male blade terminals for direct electrical interface
• Flexible polyimide film or ceramic-based circuit construction for dimensional stability
• Noble metal contact materials for low resistance and long service life
• Integral rotor bearings and return springs for smoother installation and operation
• End-of-line testing with thousands of data points to verify output voltage performance

Detailed Description

The Standard Ignition TH394 throttle position sensor is designed to deliver OE-style signal output for vehicles that rely on accurate throttle angle reporting. This part number TH394 uses a non-adjustable installed output approach, which helps preserve the calibration expected by the vehicle’s control system. For Ford E-350 Super Duty, Ford F-250 Super Duty, Ford F-350 Super Duty, and Excursion applications, consistent TPS output is important for drivability and emissions control.

This part cross-references Dorman OE Solutions 977-036 for the same application. Standard Ignition also supports broad emission sensor coverage, making TH394 a practical replacement choice when servicing throttle position sensor faults on select Ford models.

What It Helps Fix

• Throttle position signal errors
• Erratic idle or unstable throttle response
• Check engine light concerns related to TPS output
• Poor acceleration response from incorrect throttle angle data
• Driveability issues caused by worn sensor contacts or drifting output

Installation Notes and Tips

Verify connector style and terminal count before installation. This sensor uses a female plug-in connector with 6 male blade terminals, so matching the harness and terminal layout is important for a proper electrical connection. Confirm vehicle application by year and model before replacing the original sensor on 2004 Ford E-350 Club Wagon, E-350 Super Duty, Excursion, F-250 Super Duty, or F-350 Super Duty, and 2005 Ford Excursion.

Quality Assurance

Standard Ignition manufactures emission control components under complete process quality control, from component materials through finished product testing. Each TH394 throttle position sensor is validated at the end of the line to confirm output voltage performance before it leaves the factory.
