I recently did a spark plug change for a 2014 Lexus Is 250, After changing it the check engine light came on and threw a code p2017, I double checked everything to see if everything was connected properly, I didn't see any signs of loose wiring. The car drives fine and probably even better than before but I just don't know if I should keep driving it and hope it goes away by itself or it's something I should be worried about, any suggestions would be helpful thank you!

 

Welcome to the forum!

The code is for the Swirl Valve voltage being high...which usually is a good indication it's not plugged in.
Check and make sure it's plugged in.

Hey I haven't gotten time to check but is that more than likely what the issue is? thanks again for the reply

 

Assuming the code wasn't there before the plugs were changed, either the connector is not plugged in all the way or possibly the connector/wires are damaged.
