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.

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
