How to fix Throttle body on 2006 Chevy Aveo?

It only revs up when u start the first in the morning? If so, it is normal, once it warm up it will back below 1000 rpm.

Find and remove and clean your IAC valve..use MAF cleaner...you need to remove two torque screws..takes 10 minutes...spray the valve to remove all carbon...reinstall and drive car for 10 minutes to adjust..do not run lights, radio or anything else until you return and park..valve had what is called a pintle with spring around it...make sure to spray every part of the pintle and wipe in a straight motion with clean rag...cheers

What engine does it have ? Could have come with 5 different ones . If it has the 1.6 L engine . has electronic throttle control.
The throttle actuator control (TAC) system is used to improve emissions, fuel economy, and driveability. The TAC system eliminates the mechanical link between the accelerator pedal and the throttle plate. The TAC system eliminates the need for a cruise control module and idle air control motor. The following is a list of TAC system components:
• The accelerator pedal assembly includes the following components:
- The accelerator pedal
- The accelerator pedal position (APP) sensor 1
- The APP sensor 2
• The throttle body assembly includes the following components:
- The throttle position (TP) sensor 1
- The TP sensor 2
- The throttle actuator motor
- The throttle plate
• The engine control module (ECM

Check engine light lit ?

Get a can of brake clean/carb cleaner and spray all of your vacuum lines if it revs up, you found the problem.

should not have to pay for same part twice.take vechicle back to dealership tell them car not fixed you have same problem.let them know you payed them to fix car.same problem still exist.code p2135 problem could be the tps sensor or signal circuit to sensor wires and connector have a short or problem could be throttle body assembly damaged.

Not real sure but I found a link which may help

about all you can do is have the throttle body replaced, unless you have some kind of a vacuum leak, their is no adjustment or even a throttle cable on these cars..

Start with replacing the fuel filter. The Aveo fuel filter is located passenger-side rear, in front of the rear tire.

If there is no filter there, then the filter is a non serviceable filter and is integrated with the fuel sending unit. Your going to have to replace the fuel sending unit if the fuel pressure is slow, start with running fuel injector cleaner through the fuel system for the next few fill up's and hope that will clear up the issues your having.

The other thing to is that your IAC (idle air control) valve may be dirty and is stuck close, you can try cleaning it by spraying Throttle body cleaner through the throttle body, paying attention to the IAC passageway. A dirty of faulty EGR valve will also do the same thing.

Start with the simple and inspect to see if you do have a external fuel filter, and inspect the wire leads to the IAC, EGR and clean them with throttle body cleaner. Don't forget to run the fuel injector cleaner through your gas tank.

Thank you for using Fixya and good luck.

check fuel filter located under driver side attached to frame rail. or under hood driver side next to strut tower.

I bought my 2004 aveo 49 miles. I've had several issues with the car. But recently I been experiencung high idle at start up and clutching. I change IAC. Plugs and wireds. Nothing worked. Today the high idle became constant. It was a metal bubble flex tube near the IAC unit that goes to the exhaust stuff down behind the motor. It apparently was cracked cause today it broke causing the constant high idle sound like a vacumn. We blocked it off with a stick to get the idle back down to 900 rpm instead of 3-4000 rpm took we can get to auto zone for high temp hose per Chevy dealer. I hope this helps someone cause it was fustrating and costly.
