The codes are P2111, Throttle Actuator control system-stuck open, and P2135, Throttle Position sensor-faulty signal. From what I've been reading it sounds like the ETB is failing.

My 2004 S80 has been going into limp mode on an intermittent basis. It will run fine for months then start to mess up. It is now throwing the following codes, P2111, P2135, P0221, P0638, P0121 and P0507. Would a dirty throttle body possibly be the problem?
