Hey guys , new to this site.
I have a 2006 Acura TL and I was recently switching out the 3rd and 4th gear pressure switches. Everything went fine, until I started the car. VSA, Triangle icon, check engine and D light started flashing. Won’t rev over 2000rpm and when I pulled the codes this showed.

any help with this is really appreciate it! Thanks.

 

Looks like a power problem. Did you make sure everything was plugged in?

 

My guess is it's the switches you just installed.
If you have the old ones, put them back in and recheck the codes.
