Engine error codes

I have 4 error codes and I am not sure as what they mean.
p 1516 speed control
p 2106 throttle actuation control
p 2110 throttle control system
p 2135 throttle position

does any one know what these mean?

My car is an 06 Wave

thats the throttle body and/or gas pedal issues with the dbw.

start with the throttle body. cleaning or replacement might be the solution.

Thanks, I will try that. I keep getting a check engine light popping back on and off, for the last 8 months, so I hope that will solve the issues.

ive been getting p2135 very often since i bought the car. the first time, the stealership replaced the throttlebody under warr. the second time i was out of warr on the replacement part and the 36k mile. replaced it again. now im on the third one and it keeps randomly getting the p2135 code. no way in hell i keep randomly ending up with a bunk throttlebody. what gives? this is a sign of how cheap and poor quality the car really is. more trouble than its worth imo.

its probably due to the pcv system on your car mucking up the throttle body. check the valve in the pcv or add a catch can.

i also like that attitude of the cheap poor quality, it shows youve never owned an expensive car with the same number of problems, like people who do not stereotype cars by price.
