Maxisys Elite II Solved 2013 Nissan Sentra High Idle with ETB Reset

This is a 2013 Nissan Sentra that having a high idle problem. Its idle keeps really high when I turning it on. And once it warms a little bit it just drops a little bit. It stays always on 1500 revolutions per minute. So I’m going to use Autel Maxisys Elite II Scanner to do ETB(throttle body) reset for this vehicle.

 

It’s pretty much the same process for a lot of old vehicles and new ones. Should work for 2010-2017 Nissan Sentra vehicles as well.

 

Automatic Procedure via Autel Elite II
