So I got a check gas cap light on my dash then a check engine, so I tightened the gas cap a few more clicks, waited a 3-5 days never went away. So I plugged my bluedriver obd2 reader and read 3 codes, I already swapped the vapor canister purge solenoid valve with a new one from the dealer ship , new oem gas cap from the dealership, all 3 codes are still there, I did a smoke test from the hose that connects to the bottom of the purge solenoid valve in the hood, made sure the smoke went all the way to where you pump gas, closed it up and the only smoke that came out was throught the leak detection pump filter which I heard is normal when the car is off, so thats where I am at now, I don't know if I should swap the leak detection pump (ESIM) next or would it be a waste? Anyone got a similar issue or had a similar issue ? I've been trying to battle it for like 2 months now.

 

Can you clear the codes?

 

I can't it tells me permanent trouble codes can't be cleared by any scan tool

 

Hhhmmm.... dealer can probably do it.... or an independent shop with a high zoot scanner.... Disconnecting the battery probably won't....
