Service light came on a week after an ecu tune.
Pulled the codes with Evoscan v2.9.
I can clear them and the same ones come back shortly after.

Codes:
c00a0

c1290

p20c1

c1242

p20ff

Car is parked inside during winter, 2012 GSR with 30k miles sporting a Buschur sleeved 4B11T. Looks like a G sensor at the very least from the shop manual. Can anyone assist in diagnosing? Trying to locate the AYC computer and sensor that may be the culprit.
I cleaned the car and pressure washed the ACD pump area.
Could really use some help here before I find a dealer and flash back to stock.

Thanks!

i recently had a g sensor fault code, same one as you. The sensor is located beneath the center dash (access from driver's footwell is easiest) You have to pull back the carpet that runs up the footwell on the right where it start to come up to the center tunnel and its behind there. I have a pic on my phone i can text you if you need it. Shoot me a pm if u need more help locating it.
