Question Throttle Body Swap & CEL's

I'm going to be switching out my throttle body (for the Vmax ported) on Friday as soon as it gets here. I've read that if you disconnect the battery before disconnecting the throttle body you won't get a CEL. I would prefer not to disconnect the battery so that I don't have to reset the radio and everything. I have a bluetooth OBDII module that I use with the Torque app on my Android phone. Using the app, I can read and clear any CEL's that I may get. If I swap the throttle body without disconnecting the battery and use the app to clear the code(s) would I be good to go and would the not return? Not sure what the codes are, or if there is any reason to not want to get them in the first place? If there are any side effects to getting them in the first place I'll just not be lazy and disconnect the battery, no biggie. Any info is greatly appreciated!

No need to disconnect the battery for a TB swap, you won't get a CEL.

You shouldn't get a CEL either way.

I didn't disconnect the battery when I swapped out mine. You'll be fine.

No CEL when I did mine, however I always disconnect the battery when doing something of that nature.

Question from Newbie

Where does the throttle body go? What does this new throttle body do to imporve the performance. Which is best? How do you change it?

What is a CEL, is that a computer code?


I know, dumb questions, but I'm new at these new fangled cars?

CEL = Check Engine Light

Throttle body is super easy to swap, it's connected to your intake, and to the air cleaner tube assembly... It takes literally ten minutes, a screwdriver and a 10mm socket.

The new throttle body he's installing (VMAX) is polished on the inside which improves airflow by reducing the restriction of air caused by the resistance of the rougher interior surface... polishing removes the roughness and improves the airflow... which increases horsepower, throttle response AND fuel economy.

There it is... the silver thing with the gold butterfly valve that you can see after I removed my cold air intake tube... four 10mm bolts hold it on, and one electronic harness plug. Unplug the harness, remove the bolts, put the new one on, bolt it in, plug it in, reattach the intake hose... done.

Also, here they are side by side... you can see the roughness of the stock one I removed on the left compared to the smooth, spiral interior of the one on the right, which is the polished VMAX model.

Saying you wont get a check engine light is a lie... You MIGHT get one... so dont be surprised if you do...

I knew 3 others who got it when they installed



I just installed it 3 days ago, didnt disconnect the battery (This was for a v6)

I got rid of the codes with torque app. no CEL yet.

Asking what the finishing of the inside of the throttle body does for the car can be sort of explained by understanding why a golf ball has dimples. The golf ball actually has less wind resistance with the dimples than it does if it was smooth - crazy, huh? Same idea here. The machined patterning cut into the revised throttle body helps airflow.

Thanks to all for the pictures and explanations.

Now I have to get one of those, a CAI and do a Tune as my first mods to
my car.
