I'm going to see if I start experiencing the same symptoms and have my extended warranty cover it.
I pulled out my old service records and here is what the dealer did with the P2135 code:

"Throttle body assembly. Verified concern and found code P2135 for TPS sensor correlation incorrect. After verifying proper signals to the throttle body assembly where the TPS sensors are it was found the correlation was inaccurate as to SI specifications and therefore replaced the throttle body assembly to address the concern. No other repairs needed."
