How to Reset Throttle Position Sensor (3 Quick TPS SECRETS)

Your throttle position sensor controls how your engine responds every time you press the pedal—and when it gets confused, you get rough idle, hesitation, stalling, and worse fuel economy. The fix? A dealer will charge you for a relearn that you can do yourself in minutes, with no tools and no scanner. There's no money in teaching you this, so nobody does. In this video, Grayson walks through three methods to reset your throttle position sensor and let your ECU relearn the correct idle and throttle response. You'll learn the simple battery method, the key-cycle relearn, and the drive-cycle approach—plus the model-specific caveats that decide which one actually works on your car. Some vehicles relearn instantly; others need a specific sequence, and skipping a step means it won't take. Whether you're dealing with a sluggish throttle, a check-engine light, or an idle that hunts up and down, these methods give your car a clean slate. Works on a wide range of makes worldwide—just watch for the caveats Grayson flags for your specific setup.
