In this video I bring you along as I fix this 2006 Chevrolet Impala that has a glowing check engine light with a couple EVAP codes P0446, P0451.

    Pretty high speed video. Thanks for sharing. I got the P0446 on my Impala, changed the vent but the light came back in so it might be the pressure sensor… Another day for that.

    I have a 2003 chev impala i changed fuel filter up and down strean oxygen sensors catalytic converter exhaust tps fuel regulator map sensor and ignition controle module engine light went off but when i test drove it once i got to 60 mph it started hesitating again. What do you think it could be

  16. Avataaar/Circle Created with python_avatars Jack Hayes says:

    Eric; For verifying the operation and accuracy of a gas tank pressure transmitter have you considered making up a filler cap with a pressure connection? This could then be connected to a low range pressure gauge or a manometer which would verify the operation and or accuracy of the pressure transmitter, as well using this same connection you could increase or decrease the tank pressure for further testing.

    I know this is an old video but and though I don't understand all the voltage stuff I can clearly understand the physical aspect of it… I have a 2007 impala which I have the engine light on, I had it put on a hand held at AutoZone which they hooked it up to their computer and it list PO455  fuel tank pressure sensor… in another box it lists PO 442,   and their answer by experts say it is mostly the FTPS … If you would answer this question, I am sure you are busy and I realize you cant answer every Yahoo on YouTube.. lol , but I would assume the location of the sensor is the same as on this 2006 impala.. This was the only impala video I could find… Assuming it`s the same, once I have it down are there any other parts that could be if it`s worth it to replace while I am at it… I really would appreciate if you could answer…I am 66 years old, I really have to fix it myself if I can for financial reasons even though it looked easy as you did it with the host and stand I will be on the ground.. I don't know , it runs real smooth, can that part cause it to not run at some point and could you give a ball part figure on what a garage would charge to put one in…. Again I know I have ask a lot and if you could answer, and if not that's good I respect that… It was a very good video and I have a very good idea of how to do it … Thanks …..

    Is there anyway you can tell me what software your using?

  19. Avataaar/Circle Created with python_avatars Matt Man Productions says:

    Wow that's a skinny fuel tank… I'm accustomed to pulling the big bulky ones that are always full!😖 And can't use the fuel pumps like you used to and use the pump to pump out the gas, dang I miss the old classics

    I am working on the exact same car with the exact same codes… this was extremely helpful. thank you.

    AIRTEX FUEL PUMPS ARE JUNK. BUY AC DELCO OR DELPHI FUEL PUMPS. THEY ARE EXPENSIVE, BUT REPAIRING MORE THAN ONCE ADDS UP QUICK.

    I bench tested a fps for a Saturn at 1.6 volts is that too high at atmospheric?

    Hi, I'm having issues with my 13 impala. The right turn signal stops working after 30 mins from being on, but starts working again after being off for some time. Any ideas of possible causes?

  25. Avataaar/Circle Created with python_avatars The Overclocker says:

    I had a evap solenoid go bad now if i were working on one Id buy or rent a vacuum pump to check the solenoid u can troubleshoot the solenoid to see if its the problem or its a leak in line between solenoid and intake the hoses tend to leak causing this code too . If the solenoid is leaking this issue can happen too thats what the vacuum pumpp will test.

    Just rewatched this because a 2006 Impala came in to my shop "Parking lot" with the same Evap Code Advance had pulled a PO496 too but when it got to me it wasn't there and it also had a Fuel Trim limit reached. I checked the Purge and Vent with the Purge and Seal car chugged but tank sensor never changed it was fixed at 12.66 mmhg and 0.22 volts. Dropped the tank unplugged the sensor went to zero plugged the new one and it went to 1.49 volts. Ran the purge and seal again and all was well. I also gotta plug Eric's video on Malibu runs like poo this Impala also had -18% on Long Term the Alcohol Content was at 22% reset the Fuel Composition and the Impala runs great. Eric You the man Thanks again!

    Cool safety glasses bra.

  28. Avataaar/Circle Created with python_avatars Brian Staples says:

    Great info Eric. Thought your video on EVAP was my life saver, but something else is going on. 2007 Impala throwing P0172(Rich bank 1),but the only monitors not finishing are EVAP. Short term -3.1%——Long term -21.1%. EVAP purge 0%…Alcohol fuel 50.2%. All o2's check out.. Do you make house calls? LOL What gives?

    Your videos are informative and easy to understand.
    But do yourself a favor and throw out that wooden ladder and get a Werner or something comparable.
    Your wooden ladder is outdated and dangerous.
    I seen a guy fall off one not 3weeks ago.
    If you can afford that scanner , you can afford a decent ladder.
    Stay safe , your videos are great.

    I have a 2009 Chevy Malibu with code P0451 and a strong smell of gas when near passenger rear. No smell in the cab. No other symptoms other than lowered fuel economy. Any ideas before I pull the tank?
