Same here on my 2019 silverado I had the 499 code replaced the canister vent solenoid and my engine light is still on, took it back to shop this morning and was told it’s not getting enough voltage
Got a new evap canister and solenoid valve and fuelcap and pcm on my 2006 300c hemi and still p0499 code. My old pcm did not throw the p0499 code. Wonder if previous owner deleted evap system in old pcm or is my new pcm not corresponding with evap system?
