What are the methods for Honda throttle body reset?
2 Answers
Honda throttle body reset methods are as follows: Method 1: Turn the key to the second position (where all dashboard indicators light up). Wait for 20 seconds, then fully depress the accelerator pedal. Hold for about 10 seconds, then release. Turn off the ignition and remove the key - initialization is complete. Method 2: Turn the key to the second position and maintain for 30 seconds. Then turn off the ignition and remove the key. Note: After completion, wait 15-20 seconds before starting. Then start the engine and check if acceleration is normal and if the engine warning light is off. If unsuccessful, repeat the previous steps. Method 3: Remove both the Electronic Throttle Control System (10A) and Electronic Fuel Injector (20A) fuses. After 30 seconds, reinsert them to their original positions - throttle body reset is complete.
Speaking of throttle body reset, based on my decade-long experience with Hondas, it's a must-do after cleaning - otherwise you'll face unstable idle and increased fuel consumption. The battery disconnect method is most reliable: turn off engine and electronics, remove negative battery terminal, wait 10 minutes for ECU to forget old position, then reconnect and start. The ECU will gradually learn the new throttle position - don't worry if it shudders a bit at startup. If that doesn't work, try turning ignition to ON position (without starting), press accelerator fully for few seconds then release, and turn off. After reset, drive a while to adapt - saves money and hassle. I always remind friends never to skip this step, safety comes first.
