"p2135 Throttle position sensor A/B voltage correlation"

anyone know what is it? Should I be worried while driving the car? my car only has 16000 miles.

Google says you probably are going to have to have the Throttle Position sensor or the entire Throttle Body replaced, however it looked like sometimes the dealer just reset the ECU. I'd take it to the dealer.

It has happened to a few people on the board, they most of the time get the TPS replaced.

it happened to me. Pop the hood, unclip the TB sensor.. look to see if there is any grime in it, reconnect securely. Then, just do the pedal reset and you'll be fine... If you don't know the pedal procedure search for SES reset on here
