I am getting the following codes:
P0068 and P0101. I am also getting a reduce engine power display.
I have replaced the MAF and MAP sensor along with the throttle body and now the car is in limp mode.
There has to be something else I'm missing.

Hi,

Are the same codes present? I looked at them and suspect we have a wiring issue. You already replaced the related parts, so we need to see where there is a variation from the specs.

If you look below, I started with the P0068 code. The diagnostics for the P0101 follow.

Take a look through them and let me know if you are comfortable performing them.

Take care,

Joe

Okay. It's been a few weeks because I did post changing the throttle assembly, MAP and MAF
sensors. But the MAP sensor was an OEM compatible part and not ACDelco. So, I purchased an ACDelco Sensor, and I haven't been having any issues and the codes went away. So, the OEM ACDelco MAP and MAF sensor along with replacing the 'throttle assembly for which it was used because the part is discontinued from the manufacturer. And the refurbished throttle assembly are $400.00.

Hi,

So, it is running properly? If that is the case, I'm glad to hear it and happy you were able to resolve the issue.

Let me know if there are any problems still happening. If there aren't, take care, and feel free to come back anytime in the future.
