How to replace throttle body 2007 aveo

[Pauls07]

Hello,

My TPS gave out on me and i couldn't get over 25 MPH with the pedal to the floor. Being as that you cannot adjust or change the TPS, you have to replace the entire assembly, so I did. Sorry I did not take any pics

Ordered the part from rockauto for $94.99 plus a $36.00 core charge; A1 Cardone Reman and the gasket from O'Reilly auto parts for like 5 bucks.

*** For all intents and purposes, I'm not a mechanic, this is what I did, I am NOT responsible if something happens to your car, this is merely to help those who are facing the same problem I did. If I did something wrong, please chime in. ***

Parts and Part numbers : Throttle body - A1 Cardone Reman 67-3026, Throttle body gasket Felpro 61526

Estimated time : took me 1 hour

Tools Needed : 1 ratchet, 10 mm deep socket, flathead screwdriver, pliers or small vice grip

Abbreviations : TB = Throttle Body, TPS = Throttle Position Sensor, MAP = Manifold Absolute Pressure Sensor


Step 1: disconnect negative terminal on battery

step 2 : Disconnect MAP sensor

Step 3 : Remove air intake hose, running from air box to TB

Step 4 : Remove the 2 hoses that run to and from the TB (This is where the pliers or vice grip come into play, rear coolant hose will spill a little bit of coolant)

Step 5 : Loosen the 3 10 mm nuts, and 1 10 mm bolt on the TB (the nut at the back towards the firewall, and on the bottom is a PITA to get to, but is doable)

Step 6 : Remove TB, and remove old gasket from surface, and disconnect TPS

Step 7 : Place new gasket on mounting surface

Step 8 : Connect TPS

Step 9 : Install new TB (personally, I put on the nuts and bolt finger tight, and opposites, like putting lug nuts on a wheel)

Step 10 : Tighten nuts and bolt, reconnect coolant lines

Step 11 : connect MAP sensor

Step 12 : reconnect the intake hose to TB and air box

Step 13 : reconnect negative battery terminal

Step 14 : top off any coolant lost, should be about 4-5 oz. nothing too much

REMEMBER TO DOUBLE CHECK YOUR WORK!!!

Turn the car on, watch it idle, let it warm up, take it for a spin, enjoy your work, and knowing that you saved a few hundred bucks.

Cheers

Sorry, I did not take pictures.
When I did change it out, it was like 28 degrees, super windy, and dark outside. Winters in Chicago are the worst time to work on cars lol

Thanks for this. I'm about to replace the Throttle Body on my 2007 Chevy Aveo. So it's a big help. The car is running fine, but I have a constant engine light on. Took it to the dealer and they ran the diagnostic code reader and got P2135 THROTTLE PEDAL POSITION SENSOR FAULT,INTERNAL THROTTLE BODY SENSOR FAILURE,RECOMMEND REPLACEMENT OF THROTTLE BODY+RELEARN/REPROGRAM,ESTIMATE=$900.00. I 'm like no way, I only paid $4000 for the car three years ago. So I ordered a Genuine GM 25183237 Throttle Body from Amazon for $135 and a Fel-Pro 61526 Throttle Body Mounting Gasket for $3.89. I'll post back after I finish the job. Thanks again for the instructions. Pictures would have been nice but I found a few videos on youtube to help as well.
