Default Crazy Throttle Body Noise?

Hi everyone! Its my first time

I have a question. I have a high pitch noise coming from the Throttle body when I have the key in the on position with out the car running... cant start it. Also some random clicking in there.

The code I am getting right now is P0123. The book says Throttle Position?

Also P0222, cant find the code for that.

Anyway, anyone know if this could be causing my car not to start? Lease it happened in my garage.... LOL!

REWARD EXCELLENCE!

P0123 Throttle position sensor 1 circuit high voltage

P0222 Throttle position sensor 2 circuit low voltage

Yes, this may be a throttle actuator issue. There may be a loose connection worth checking - exercise the connection by disconnecting and reconnecting several times and try the ignition again. The electronic drive-by-wire system are the throttle actuator control (TAC), accelerator position pedal (APP) sensor, and the ecm. Normally these tacs are reliable and built for longevity as you may the the first to post these two error codes for a tac fault. Hopefully its just a loose connection.

Thanks for your time!

I have unplugged and plugged a few times and still the car wont start. Is there a fuse that I should be checking?

Does having a bad throttle body cause the car not to start?

Well, its presumed you checked all fuses everywhere before, during, and maybe after troubleshooting. Its difficult to damage a tac. Either it works or its broke and no one has posted of a completely broken tac so you may be treading a new pathway..............If the throttle doesn't open when holding the electronic pedal down (have someone do this so you can see the throttle plate move) this may stop the engine from starting. (ignition must be ON to exercise the throttle body) Are there any indicators on the instrument panel?

Is the tac clean or filthy from years of use with no cleaning done? If its dirty then clean it the best way you can.
