Codes P2121 and P2122 Accel. pedal. Help.
I have these codes and the throttle is becoming less sensitive. Sometimes it goes half way down before I get power, sometimes it's hard to maintain an even speed.
I also have a check engine light.
I also have a P0602. Control module programming/not programmed.
I'm running a Smarty, but have made no changes in the programming for a couple of years.
270,000 miles on the truck.
I've searched and am doing the APPS reset and battery disconnect thing. Where are the grounds people talk about cleaning?
Any ideas?
Thanks.
