You are brilliant. Can I bring my 2009 chev colorado 2.9 four to you. My cam phaser is coding intermittently
Oh that makes sense why other shop thought there was a electrical issue they used a DVOM when they saw constant battery voltage good Work Showing the oppsy from the other shop Tech I agree test lights work better then DVOM on Control circuits Eric O @SouthMainAutoRepairLLC
The shop couldn't fix or diagnose a Bad Vent Solenoid 🤔🤔 interesting makes you wonder Eric O @SouthMainAutoRepairLLC
I'll be
I did not even have an evap issue, but enjoyed the video anyway….
Pops hood only to find it's got a Sloppy stage 3!
Po449 Chevy 1500 99 Silverado runs ruff at idle any ideas
These truck ain't worth sh%t! I have one and don't know if its worth fixing!
Great explanation. The meter is very high resistance on D.C. voltage scales.
Oops.
South Main auto,great workand good lesson. Hod Bless.
Good lesson, great work Eric.Keep up your awesome work. God Bless.
Change the camshaft on the exhaust side
Lol
After watching the series on the Colorado, that lasted more than some tv shows, it seems like you didnt take the easy ones…
That probably already knew that they werent gonna get to the bottom of it, and thats why it got shipped off!
Almost the exact situation occurred when a electrician's helper I hired was helping me rewire a rat's nest created by a previous homeowner. The "helper" was in a trance for 15 minutes staring at his DVM which was indicating about 70 volts AC on a wire that shouldn't have been connected to power. I ran and got my old fashioned Simpson 260 which has a much lower impedance than his DVM and got a 0 volt reading instead. He acted amazed that I found this and I was amazed that he was not aware of phantom voltage from capacitive coupling since he was an electrician. Maybe he was milking the job…who knows.
When I’m NY are you located? I need a trust mechanic
Oh, I forgot, one last bit of info: the truck doesn't overheat coolant but the gage shows it does run hot.
The PCM Control side is probably Tristate, that is what causes the impression of a ground on a DVM.
But can she do it?
Im a bit confused, should both the white wire and the red wire have 12 volts flowing thru them? and when the siliniod needs to kick on the red loses power. or no?
Does anybody up there ever clean their cars? It seems like most of the cars you work on have the interiors of a butcher's dumpster!
Great diagnostic and fix.. thanks for taking the time.
Thanks for the video.
Eric, I have an 06 Colorado with 0017 code. It needs a timing chain……………LOL, just kiddin'!
Vent valve: Duralast PV428 is $24…(04-05) GM 20941985 (06-12) Electric plug (Wells 1161) is only difference. Just heat the hose with hot water and switch it to the new one… Try cleaning the valve first… 12vdc and blow into it and it should be closed when powered… Valve comes off the housing… Tab is on top and turn it 90°. OR the Fuel Pump corrosion issue…
Great job.
May I ask you about a jeep grand Cherokee that I am trying to fix?
Good video I grew up outside buffalo not to far from you
Great video!!
My vent solenoid checks out fine but not getting any power to it. Checked fuse and it's good. Broken wire?
Excellent stuff showing the need to load circuits like solenoid valve control circuits when checking for command signals. When doing this with a multimeter, it should be equipped with a LoZ setting, but, typically those only come on specialized or high end multimeters. It's a lot cheaper to carry around a 100 Ohm/3W resistor (which doubles as a pair of backprobes).
Hey I was wondering how much is the program you have on the computer or tablet for any Dtc/Mil/functiontests
Whats the part number of the scope on the rope?
Coil is "high resistance open".
give them an SMA sticker, problem solved.
I actually had an identical vent code yesterday and I was scratching My head then I ohmed the coil and it was open so it was fixed nice explanation
Cool video Eric O , I had an 04 Colorado ( bought brand new in 04) with the inline 5 / 3.5 liter I believe it was , and I never cared for that vehicle, It started running like crap at around 75 to 80,000 miles using in my opinion more gas than it should have , and would occasionally stall but start right back up and run OK for a bit and then do it again in a month or 2 very annoying!!!
What great series of videos and just the help I needed to tackle my own Colorado P0449 and P0017. Thanks!
Great job Eric! Whew…Just finished all 5 episodes… what was the mileage on this POS?
thanks …
great point eric thank you for sharing mark
Nice Fix Dude.
Do you not own the LOAD-PRO test leads? from Dan sullivan? Because you can test the whole wiring harness for voltage drop with the push of the button with the patented load pro lead . Even the shroedinger box now owns the leads i think i might have managed to convince him to buy them "ohms law matters " dan sullivan is 100% correct. Your methode also works but Dan sullivans tool is like the ultimate time saver.
i know one can have to much tools but that accessory is a must have if time is money.
Good job explaining how the computer checks for opens and shorts. For those vent solenoids Eric how much current do they usually pull? Your spot on about meter usage, have to understand what the meter is telling you and be aware of circuit operation. Thermo King Computers put out a bias voltage on the ac clutch circuit, not battery voltage but it is around 4.2, 4.3 Volts, you will see this value with your voltmeter in the power and ground of the connector unplugged. So to test dynamically either plug the circuit back in to check or how I like to do I use the Loadpro to fool the computer that the load is plugged in. Takes a minute for the computer to recognize a complete path but when it does if I have a good circuit path it will give me full system voltage on my meter which is the volt drop across the Loadpro resistor.
I'd love to see a full nerd explanation of what was going on. I would think the impedance of your test light also has an effect on the meter reading. I'm a big fan of voltage (drop) testing of loaded circuits. I was worried that you may have 'fixed' the problem by disturbing the wires when you unplugged the connector.
Eric are you going to the Vision Hi Tech Training expo? I"ll be there. Asked Ivan too. You guys should come, the top trainers in the industry will be there.
Really really Great job……..i love your job sir
So, let me see if I have this straight: The PCM signals the solenoid to open by yanking it's ground forcing the voltage to use the solenoid's ground, thereby "seeing" 0V, signifying that it's working not just passing current? Sheesh. What a "lovely" idea… 🙁
I like to try and catch all the nicknames you throw in the videos such as "One wheel peeler". By the way, you haven't used "all zippy zap like" for removing a bolt in a while. Just sayin. Great explanation on the meter issue!
