    I got a check engine light on my ‘14 impala - no other symptoms. Bought a tester at the local store for about $35. Got error code P0496. Bought purge valve on rockauto for about $27 including shipping. That was over a month ago, no more check engine light.

    Great video, only thing I would add after dealing with emission codes on my Cadillac Dts. Make sure you get GM genuine parts like sensors or a purge valve. I changed everything from a pump to the check valve and all the sensors. Turned out to be one of the cheap sensors wasn't working correctly and that was throwing my code.

    Wow I had a 2014 tacoma that started trying to stall out at red lights and difficulty starting after fuel ups and had to pump the accelerator while starting to get it to crank over. Went to toyota and to another mechanic and toyota did the 3 point fuel injection cleaning but didnt fix issue and other mechanic said put fuel additives in or use top tier fuel like Chevron but that also didnt help. I traded the truck in and all that time it was the fkg purge valve based on this video...funny part a friend who builds cars (works on his own vehicles) recently said the same thing. I swear getting a proper diagnostic that fixes an issue from a paid mechanic is nearly always a scam for a more expensive repair or to just avoid the work and get you off the lot for a diagnostic fee knowing they didnt fix the issue.

    .I hear a screeching sound coming from my gas tank and then my idle drops and it has cut off on me when slowing down to a stop. I thought this was the fuel pump so I replaced it and then shortly after it began again though the idle it stronger but it still drops my idle when it happens. Also, I replaced the purge valve solenoid as I get the error code for that off and on. Any thoughts?

    • @HVAC_Mechanic

      It needs to be diagnosed, but when there is fuel leaking from the charcoal canister, usually that means there is high pressure in the EVAP system or lines were mixed up somehow.

    Hey Bro. My wife's 2003 tahoe started throwing the P0442 code last week. Vehicle ran fine for about 5 days. Today, I went out to start it for her(cold Idaho morning), and now it just turns over but no ignition. Anything you can tell me pertaining this code that would cause it to just not ignite? My Wie literally drove it the day before and no problems. Thanks in advance if you see this.

    • @HVAC_Mechanic
      @HVAC_Mechanic  6 месяцев назад +1

      It should still start and run with a P0442 EVAP code; there must be another issue. If the purge valve gets stuck open, it may cause it to run rich or idle rough, but it would still run.
