I have a 98 c1500. 5.0 l V8 Stopped at a light then upon acceleration it woulndt shift past 2nd great. CEL came on. Giving me co221 co222 and co237 codes. And light is NOT on.

C0221, C0222 are your left and right wheel speed sensors. C0237 is your rear wheel speed sensor. It looks like your computer has lost contact with all of your speed sensors and can't tell how fast you are going and is basically freaking out. Check your ABS and Traction Control(if you have T/C) fuses. Other than that, I would seek help of a good diagnostic mechanic.

My Rodeo 2004 is showing ABS and Brake light on Dash. Mechanic check shows error CO221 RHF ABS channel in release 2 long. Whats the problem?

Check the wiring to the sensor on the wheel on the front passenger side. Look for any areas that are worn etc. If there are any, repair them. IF you don't find any check the connections and then replace the sensor.
