2014 Challenger Leak Detection Pump?

Any advice or pro-tips on replacing? Got multiple EVAP codes on my car, and already replaced the Gas Cap twice. So gonna do the LDP next.

Do you know the codes? You can search specifics on the Chilton site

If the code is showing a small leak, they are a PITA to track down. Shops usually use a smoke machine to help identify the source. Although, sometimes you can get lucky by inspecting the hoses going to and from the EVAP canister. I think on year model the EVAP purge solenoid is located near the passenger fenderwell in the engine bay and those hoses are subjected to a lot of heat making them brittle. Good luck!

Good luck! My old car was in multiple dealers for a small Evap leak, and it was never resolved. Gas caps, gas filler, did no good. They smoked it about 10 times and never found it. When I traded it in, I had just had another dealer try to find it without any luck. Almost all of it was covered under emissions warranty, but they did whack me 20 bucks for a $3.00 gas cap once. The only thing it caused was a CEL and no remote start. No big deal in the summer, but in the winter, I really missed a warm car in the morning.

Can a Tuner shut off the EVAP system?

Yeah, but if you live in an emissions state, you might not pass. In IL I believe you are allowed 1 monitor to be incomplete though so you would pass.
