Hi, My name is*****'m happy to help you. During our conversation, I may be presenting you with different things to try, and ask you some Questions to get a better understand of the issue so I can answer your question properly. So stick with me to the end, and I am sure we should be able to get this issue resolved for you! Did you have this same code before you changed the throttle chamber? Also, did you clear the codes after you replaced it and perform a Idle Relearn? 1 last thing. Where did you buy this throttle chamber? Let me know..

I did clear the codes after replacing the throttle body however I did not do the idle relearn

Thank you. When it comes to after market electrical parts they never work right. This code is for a Throttle Position Code. There is two throttle position sensors in the throttle chamber and you get this code when one of them is out of spec. The only real check is to see if the 5 volt reference is there to the sensor and that the ground is good. Other than that, if those two sources check out, then you have a defective after market throttle chamber which would not surprise me. I have had to change these many times cause they never work right. When it comes to electrical parts, stick with the dealer. You have have anyone else install them, just get the parts at the dealer. Yes they are a little more money, but they work with less headaches and wasted time. Do you have a Volt meter to perform the diagnostic steps for this code if I gave them to you?
