Detailed Description

Standard Ignition TH294 is a throttle position sensor used to report throttle angle to the engine control system. Accurate throttle input is important for fuel delivery, idle control, transmission behavior, and overall drivability. This sensor is listed for 2000-2002 Subaru Legacy, 2005-2006 Subaru Legacy, 2000-2002 Subaru Outback, 2005 Subaru Outback, 1999-2005 Subaru Impreza, 2005 Saab 9-2X, and 1999 Subaru Legacy with California emissions. This part cross-references Beck/Arnley 158-0916 and Walker Products 200-1237 for the same application.

What It Helps Address

• Throttle angle signal errors
• Rough or unstable idle caused by incorrect throttle feedback
• Delayed throttle response
• Check engine light concerns related to throttle position sensing
• Driveability issues tied to inconsistent sensor output

Installation Notes and Tips

Verify connector style and terminal layout before installation. Confirm vehicle year, make, model, and emissions configuration against the listed applications, especially for the 1999 Subaru Legacy California-emissions application. After installation, clear diagnostic trouble codes if needed and confirm throttle response with a scan tool or road test.

Quality Assurance

Standard Ignition is a recognized aftermarket source for engine management and emission control components. TH294 is built to match the listed connector and terminal configuration for the specified Subaru and Saab applications.
