KUGT4 Posted July 31, 2016 Share Posted July 31, 2016 what does 'Make sure that throttle valve moves during above 10 seconds by confirming the operating sound' mean? Quote Link to comment Share on other sites More sharing options...
GMballistic Posted July 31, 2016 Share Posted July 31, 2016 What are you trying to do firstly? If you are trying to reset the ECU in order to cancel the EML then you don't need to do that part at all as that is a separate procedure for "Accelerator Pedal Release Position Learning". Below is all you need for the ECU reset if that is what you want to do... ECU Resetting Procedures Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON. A stop watch or an analog clock with a second?s needle will be useful. Operations Procedures 1. Confirm that accelerator pedal is fully released, turn ignition switch ?ON? and wait 3 seconds. 2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds. 2a. Fully depress the accelerator pedal (HARD). 2b. Fully release the accelerator pedal. 3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking. 4. Fully release the accelerator pedal (while the CEL is still blinking) 5. Wait about 10 second. 6. Fully depress the accelerator pedal and keep it for more than 10 seconds. 7. Fully release the accelerator pedal (The CEL light will continue to blink). 8. Turn ignition switch to ?OFF? position and now you can start the car. The CEL light should be gone. If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU. Quote Link to comment Share on other sites More sharing options...
KUGT4 Posted July 31, 2016 Author Share Posted July 31, 2016 (edited) cheers, its part of the 'throttle valve closed position learning' procedure following an ecu reset part of that procedure involves 'Make sure that throttle valve moves during above 10 seconds by confirming the operating sound' Not clear what this means Edited July 31, 2016 by KUGT4 Quote Link to comment Share on other sites More sharing options...

My car is idling 950rpm and I'm looking to reset the throttle. How is it possible to move the throttle valve when it's inside the throttle body?

davey_83 Posted April 24 Share Posted April 24 It's just means moving the throttle butterfly. Pedal dance for idle speed reset will sort you right out *carried out on warm engine Quote Link to comment Share on other sites More sharing options...

Cosmic73 Posted April 25 Share Posted April 25 I felt like a monkey, pressing random keys on a type writer, but it seems to have worked. Idle has now dropped from 950rpm to 750rpm. Not sure if that's right but it's better then it was. 1 Quote Link to comment Share on other sites More sharing options...
