What It Helps Address

• Throttle signal errors that can affect acceleration response
• Rough or unstable idle caused by incorrect throttle input
• Delayed throttle response during tip-in or light acceleration
• Check engine light conditions related to throttle position sensing
• Fuel control issues tied to inaccurate throttle feedback

Installation Notes and Tips

Verify connector style, terminal count, and sensor orientation before installation. Confirm fitment by year and model: Fits 2003-2006 Mitsubishi Lancer, N/A; Fits 2003 Mitsubishi Outlander, N/A. After installation, clear any stored diagnostic trouble codes and inspect throttle response at idle and under light acceleration.

Quality Assurance
