here is what you do manual with out as an tool if the throttle closed position is not learned

Have you reset the throttle body? Modern fly by wire systems, If disconnected, need to relearn their parameters. The process to reset is not the same for all cars, but generallly follows a similar pattern, for example by pressing the throttle, holding it whilst turniing ignition on and off a certain amount of times.
If you google, you’ll find it.

Here is the Note reset procedure, it may be the same?
1. Perform EC-857, “Accelerator Pedal Released Position Learning” . (ignore)

2. Perform EC-857, “Throttle Valve Closed Position Learning” .(ignore)

3. Start engine and warm it up to normal operating temperature.

4. Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.

5. Turn ignition switch OFF and wait at least 10 seconds.

6. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.

7. Repeat the following procedure quickly five times within 5 seconds.

a. Fully depress the accelerator pedal.

b. Fully release the accelerator pedal.

8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MI stops

blinking and turned ON.

9. Fully release the accelerator pedal within 3 seconds after the MI turned ON.

10. Start engine and let it idle.

11. Wait 20 seconds

if load value in pcm is 33% carry out self learning control you are supposed to but it said release the hand control and didn’t do anything so stuffed if I know I’ll update when I try on the next car
