So I just installed a fast 90mm and an LS2 90mm throttle body on my '02 Z06. Then I got it tuned and all was good and the car ran great.

Long story short the throttle body I put on I was only temporarily borrowing from a friend so I had to return it to him after only about a week of using it. The next week (yesterday) the ls2 throttle body I ordered for myself arrived and i installed it.

The car seems to run fine but I am getting these codes now-

P1220 TP sensor 2 Circuit –A
P0153 Heated Oxygen Sensor (HO2S) Slow Response Bank 2 Sensor 1-A
P1516 Command vs Actual Throttle Position performance (TAC ,module) -A


BTW I'm using a harness adapter I ordered online from corvette central and I double checked that everything is hooked up correctly after the throttle body install.

Any idea's why these codes would suddenly pop up?

Thanks in advance!

Maybe its an LS3 90mm throttle body.. I heard they will give a C5 problems and you need to make sure its a LS2 specific throttle body..Other than that or a bad connection...Or maybe low voltage on the battery. Low voltage on a battery will throw all kinds of crazy codes..

There's a conversion harness you'll need I believe that makes the C5 think it's a C5 throttle body.

Already have that. That's the harness adapter I stated in the first post.
