T. P. S. Issues
Ok.
Here is the story. I purchased a set of IForget Evolution wheels form a forum member. They are fitted with a set of GM sensors. The dealer and a corvette shop have tried to det the TPS but no luck. I get the "Must Service TPS" on the DIC and no reading. I also cannot get into competitive driving mode becuz of this issue. How do I fix it? The service guys at the dealership are clueless. By the way this has been an on going problem for a year.

Read some of the threads in this link:

Some of the threads in that link above have some pictures of how your sensors may be strapped inside the wheel or mounted with brackets. Either way, they are often too far inside the wheel for the signal from the sensor reset tool to be able reach the sensor to trigger them during a relearn procedure.
You'll see that many iForged owners have your problem. Below are some pictures of an exotic wheel (I think an HRE) that has some holes drilled in the back side of the wheel to mount the sensors in the OE manner with the valve stem sticking out the back side. This mounts the sensor close to the sidewall of the tire so the tool can trigger it, and it also mounts the valve stem of the sensor (which is part of the antenna circuit of the sensor) sticking out of the wheel so it will send a good signal to the receiver in the TPMS computer in the car.
Good luck!!

Below is a picture of the valve stem used for inflation of the tire. For cosmetic purposes it is mounted so it looks pretty, and you can see that you can't mount the sensor in the normal manner it's mounted in a stock wheel:
The pictures below show the back of the wheel. They have machined a hole in the wheel to mount a sensor in the OE manner, but on the back (inside) of the wheel for cosmetic purposes. I think that thing in the hole is just a plug to stop up the hole. If you mount a sensor in there you would remove that plug and just mount the sensor with the sensor inside the wheel and the valve stem sticking out of the wheel rim - just like in a stock GM wheel, but on the back/inside.
