How to Relearn a Throttle Body After Replacement (Step-by-Step)?

Relearn a throttle body after replacement by turning ignition OFF for 10 seconds, then ON (no start) for 3 seconds, fully pressing/releasing the accelerator 5 times in 5 seconds, turning OFF for 7 seconds, and starting the engine—idle calibrates automatically. Ideal for Toyota and Honda; use OBD2 for Ford/Hyundai. Check for no CEL.

What Is Throttle Body Relearning and Why Do It After Replacement?

Throttle body relearning adapts the ECU to a new throttle position sensor in electronic throttle control systems, preventing idle surges, check engine lights, or limp mode.
