NEED HELP FROM EXPERTS on APP sensor P2122 P2127 P2138
I really need some s2K expert to help me with this issue
3 months ago, I drove my 06 S2K on the track, right after a hard turn, all the sudden, the VSA and Check engine light both turned on and the power will cut off at 4K RPM on every gear. I shut down the car, restarted, the check engine light will stay on but the VSA was turned off went out, it happened again when the car is turning hard especially when the rare wheel slip a little bit. I cleared the code and tested it, it did not help. All the codes i got was P2122 and P2138.
After I went home, I tested the car multiple times and the problem started getting worse. It eventually may just happen when I make a fast turn on the street (It was not happening when i drive it on the street). I found out online that the codes was about APP sensor malfunctioning. I ordered a new APP sensor and put it on, then the problem fixed. I went three track days and it worked well. But on the fourth track day, the problem happened again as soon as i turned on the engine. I cleared the code and this time i disconnected the app sensor and reconnected it, then i lasted a whole without any trouble. When I thought it was fixed, on my fifth track day, it happened again as soon as i turned the car on and it started acting like it was 3 months ago no matter what I do. I tried to reconnect the sensor, I tried to drive it with either VSA on or off. None of those would prevent it from happening. But this time i got a new code and it was P2127. It does not make sense the sensor is broken again just after 3 months and I most only drive it to the track, it was no more than 1000 miles usage. Many ppl tried to help me figure it out what is wrong but no one really have a clue. I would not keep on spending $ on the sensor since they cost almost $150 each. Has this ever happened to anyone else and it was figured out? Please help! I really appreciate it. Thank you

I have an 06 and had experienced the same issue with VSA light and CEL on with 4k RPM limit. It happened to me on a random rainy day. I did couple of things that cured the issue; 1: I had a much needed valve adjustment job done. and 2: I did a "Map sensor whack" and the problem has not returned yet (knock on wood) 30k miles so far.
Hope this works for you

Could be one(or more) of your pins in the ecu could have a bit of build up on it/them and not transferring a clear signal from the wiring harness connected to it. Disconnect the wiring harness and clean off the connection pin in the ecu and the wiring harness connectors with some compressed air.
