Good to see you back again. The way I was taught, basically open loop means that the computer isn't using the oxygen sensor/s to determine the fuel control strategy. It uses the TPS, MAP, MAF, and all other engine input sensors, but ignores the oxygen sensor/s reading. Closed loop means it uses all of the above plus the oxygen sensor/s.

First thing to do, replace the gasket on your gas Cap. Esp if the car is old. this will cost you around $20 or less. I got this evap code, reset it, a week later it came back, I checked my gas cap and it didn't really feel snug like a new one, so I checked online and I found a recommendation to replace gasket. worked for me.

Thank you for making the video. You are a natural teacher. I really appreciate the background information that really helped me understand how the evap system works. I assume that, if the purge valve had been good then the next step would be to pull and check the valve by the gas tank. I think I will be able to fix my car now thanks to your video.

Wow, not surprised, but people have short attention spans. I guess this sorts out the good mechanics from the mediocre ones. Really appreciated this video and thought it was well instructed and well produced. The point he makes (which those with lazy attention spans will never understand) is that a little critical thinking in advance and a good understanding of how the systems work saves time and parts costs in the end, because rather than just diving in and randomly swapping out parts (at your customer's cost), we try to pinpoint the most likely cause of the problem from the start using the information the car is giving you. The answer is there - but you need to learn how to analyze the data first. Too bad more mechanics don't take this approach. Will be watching more of his videos. Totally impressed.

This is all for OBD-II vehicles that have scan tools, PID's, and enhanced monitors. OBD-I (vehicles made before 1996) have it much harder. Still a great video. The diagram and description of the evap system is spot on. Not all vehicles have electronic canister vent valves or pressure sensors. Have to take all of this into account when diagnosing a vehicle and adapt these procedures for the vehicle design that you are working on.
@PineHollowAutoDiagnostics9 жыл бұрын
+DJDevon3 Never seen a pre-OBDII vehicle set an EVAP leak code...so there's nothing to worry about! On that note, I find it silly for the "Check ENGINE" light to come on for issues that have nothing to do with the engine/driveability.
@DJDevon39 жыл бұрын
motoYam82 Not setting an evap leak code (because it doesn't exist on your OBD-I vehicle) is even worse. Good luck figuring out there's an evap problem. :P You might get a faulty solenoid code if you're lucky but that's about it.
@PineHollowAutoDiagnostics9 жыл бұрын
+DJDevon3 But the system itself is simpler with no canister valve, since there's no need to check for leaks anyways. The only electronic part is the purge valve which could fail mechanically and not set a code. Otherwise you just use your nose to check for leaks...if it smells like gas fumes, you have a leak lol

A very good and informative video, so funny some people commented the video that is not helpful or saying that too much of a talk. If you guys are only thinking of fixing the problem without understanding what is happening to your engine there's two things thst might gonna happen, either your car engine problem migjt get worst or you fix it right. I like the way he explained everything as i clearly understand how things works👍. By then if you send your car at the shop, those greedy mechanics will not be able to fool you the way they steal money from our pocket. Regarding with the tester he used, he's not promoting and or selling what he's using i guess, it's just that, that's what they are using in their shop? We shiuld be glad and appreciate this kind of person sharing us some information what to look for if there's some problem in our car engine.

After watching parts 1 and 2, a smoke test would not find this type of small internal valve leak, so we get a lesson on second level diagnostics for evap. To those critical of his fancy computer, getting good data need not be expensive..Various OBDII scanners are avail from ebay or amazon for like $22 (bluetooth to smart phone) or USB to your laptop. You can download and use several free apps or buy cheap add-ons to decode much the same data as the $4500 computer produces. The main limitation is your investment in time and understanding how to maximize the apps and what the significance of the data is.

I just subscribed to your channel. You are a natural teacher and great at it. After watching this video and pt. 2, I learned more about my vehicle and how it works. I think it now helped me to know what to look for as the engine codes come alone or my CEL stays on like it's staying on now. My mechanic is currently in the process of replacing my PCM on my Honda Accord v6 because we have gone through every repair or part replacement you can possibly imagine, but the CEL never stayed off. We think it needs a new PCM/ECM which is what the first auto repair business told me too. I want to get a diagnostic tool like you have. How much does that one cost?

@edgerrr5 ай бұрын
To add to my previous post about checking the easiest thing first and my issue being the purge valve on a 2015 Charger, it took more than a squirt of WD-40 to loosen things up. The valve required some throttle body cleaner as well as a couple shots of WD-40 but I think it's finally loosened up. One thing of note is that it's NOT a completely ON-OFF type solenoid in my case. Bluedriver OSB-II shows that it is analog in nature meaning it's variable. New valve is about $25 without tubing to manifold or about $40 with tubing to manifold. This matters because tubing to manifold is difficult (but not impossible) to remove from valve.

A small evap leak could be sign of bigger problem. I had p0442 code too and thought it was a small problem. i did exact thing what u said on video and couldn't find anything. So i tapped out and took truck to shop. they smoke test it and found out i have a small leak coming from top of gas tank where sending unit and sensor is located. if u have older car thats rusty underneath i advise you to have the shop trouble shoot for you.

Everyone is a teacher, but not everyone is a good one, and you Duane, you are a stand out! I have a few questions. In order for the monitor to check for the leaks, both valves have to be closed. How did the canister vent valve close? since it's open when the engine is off. On the large & medium leaks, system passed, , how do you interpret the values shown? what I mean, how would you know whether those values are optimal, or on the borderline of a leak? Again, thank you for video and the wealth of information
@realfixesrealfast8 ай бұрын
Thanks for the kind words. Great question but not an easy quick answer. The ECM has built-in controls for the systems it monitors. So the ECM closes the valves when it starts the test and opens them based on the test results. You would need programmer instructions to get the actual answer. Keep in mind all electronics are simply voltages and ground. All ECMs are binary devices which means they can only read 0's and 1's, not voltages. All data is converted to 0's and 1's and is either an input or an output. Programmers ask the questions as "if, then" format. example, if the valve is open and the test is requested to run, then close the valve. The test runs, results are reported, and the next "if" question is asked. The EVAP test answers are based on time. For example, how long did the vacuum hold? The answer determines the next response (action).
