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!

I would check if the wires are in the correct pins on that extension harness. Here is a link you can use to help you. https://ls1tech.com/forums/pcm-diagn...odes-help.html. Hope this helps.

Dos the TB have a gold blade?

The blade is silver..

The pins on the harness can't be wrong because the ls2 throttle body i had on it previously worked perfectly.
