CEL Codes and Help Please.

Hey guys whats up, so on my way home last nite, Once again The CEL turns on and I was like what now. So took to auto store, and 3 codes this time came up.

U1120 --LOST WHEEL DISTANCE MESSAGE

This fault code will set when the PCM does not receive an electronic vehicle speed message from the ABS or Anti lock Brake module.

Possible Causes
CAN C BUS CIRCUIT OPEN OR SHORTED
ANTI-LOCK BRAKE MODULE
POWERTRAIN CONTROL MODULE (PCM)


P0430
--- Catalyst System Efficiency Below Threshold (Bank 2)


P0710 ---- Transmission Fluid Temperature Sensor Circuit



So This is the 2nd time I got P0710 and the other 2 are new. Im not sure where to start with these for repair or fix. Super busy with helping father around house, and with my brothers boat repairing and fixing. SOo Im just looking for some help here guys, I know I can search But just dont have the time right now. And this is My daily driver!!

Hope we can find some answers, Thanks guys And like always Happy Jeepin

Before trying to diagnose each one, what shape is your battery in? When voltage is low, each of the different modules can start throwing DTCs and a new battery fixes them all.

It looks good to me, Not too sure how old it is, as it came with the truck when I bought it 8K ago. I think it is a good battery, Ill have to have it checked out tomm after work.
