I keep getting these codes

U1000 class 2 comunication malfunction(history)
B1001 Option configuration Error(History)(Immature)

U1016 Loss of class 2 Communication with VCM(history)(immature)

p0121 TPS sensors insuffient activity

I have changed the TPS sensor with one from Advance auto parts. I have even tried another AC delco sensor. What is my problem? Do I have a bad computer?
I can only clear the p0121 code with Hp tuners the others just stay there? I keep getting tps code after a few miles of driving about 5 miles. I have checked the wires as best I can from the sensor to the VCM they seem to be fine.

anyone

Have u changed cam, intake, tune or anything? Mine did the same thing but all i did was go into the P0121 and change the min. and max. error and haven't had a problem since. Its actually usually a code saying that there is too much air coming into the intake for the amount that the throttle blade is open.

Edit: O yeah and just ignore all the rest of the stuff being that none of that is important at all just the P codes and occasionally others but those are normal besides the P0121.

All of the above + heads.I found out that I had the min and max set wrong. I was idling at 62 Kpa to 68Kpa.The max was at 65Kpa when it would go above that idling it was setting the code. Thanks for the help

Figured that was the problem, glad you got it figured out because it haunted me for about 6 months before i finally bought HPTuners and found the problem myself instead of my tuner giving me the run around!

Yea I just spent $100 on 2 TPS sensors thinking I got a bad one the first time.
