My check engine light just came on and it's throwing a p0123 code.. I gotta drive back home tomorrow. So my questions are what is wrong with it and is it safe to drive with?

Did you recently have work done? I had my smog check performed and got the check engine light come on. I ran an obd2
Check and nothing was wrong. I called the shop that performed the check and they told me this often happens. The light disappears and reappears every so often but overall my girl is fine.

Jeeps are resilient. I have a feeling you should be ok

When washing the engine bay of my '02 4.0, I sprayed the top of the throttle body a little bit too closely. Water got in to the TPS sensor and it threw a P0123 code the next time I fired it up.

It's cheap and easy to replace, 30 minutes maximum.
