Guys PLEASE HELP ME!!!! I keep getting these codes
U1000 class 2 comunication malfunction(history)
B1001 Option configuration Error(History)(Immature)
C0240 Unkown(History)
U1016 Loss of class 2 Communication with VCM(history)(immature)
U1040 Loss of Class 2 Communication with ABS(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.

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.
