I have a Mazda 5 TCM with code P2119, U2023, and U2064.
- Code P2119 points to something wrong with the throttle body.
- Code U2023 indicates a faulty battery whenever it mentions an erratic signal from the PCM.
- Code U2064, indicates there is a network communication issue with a module somewhere in the vehicle which might caused by faulty wiring, fuse, relay, or bad battery.
