Although when you consider shop labor costs, most owners are better off replacing all the parts they are able to before paying for a few hours of diagnostic labor. For example, I had an 04 Altima I replaced a crank sensor for $20 myself, my boss's wife has the identical car and the shop charged them over $600. A ball joint failed on my wife's crown vic, towed it to a shop since it was a holiday weekend and I was busy, they charged over $700 for a literal $5 one on rock auto.

@@JesusSaves86AB Exactly. I can buy a ton of parts for $500. Even if I replace 5 wrong parts with the shotgun approach, my vehicle is 24 year old and 168K miles. The 5 "wrong" parts were on their way to failure, anyway -- and tow trucks cost big money these days.

Bingo!!! I've been chasing the cause of the P0401 code on my '03 Focus for almost a year... even threw a new DPFE sensor at it. After watching your video, I pulled the vacuum hose and it looked EXACTLY like the one on your example car in the video... rubbed right through. I repaired the hose with a piece of tubing, and reset the code. Hopefully, it's gone for good now. Thanks for your excellent video and troubleshooting skills!

Great explanation, Duane. I guess I would have started with the hoses, as access to computer diagnostics beyond OBDII is not avail to a backyard mechanic. You make a great point that the pro needs to stay with basics, as the temptation would be to throw parts and see if the problem is fixed. That way would have eventually led to the solution, but only after the customer might have paid for replacement of normal devices.

If you dont have a fancy scantool you can disconnect both DPFE hoses, and draw a bit of vacuum on the DPFE (maybe 5 Hg or so)and monitor its voltage using a multimeter or scantool. If there isn't a linear relationship(voltage jumps around) the DPFE is implicated. Remember the DPFE is measuring the difference in pressure between the two ports.

@mrfordexplorer97 Sounds like you got a plugged port. To check there is two ways. One is to pull the vacuum line and apply vacuum to the EGR while the engine is running. If it stalls the port is clear. If it does not stall the port is plugged. Or you can remove the valve and plug the vacuum line start the engine to see if you got great suction on the intake side of the EGR if you don't the port is plugged. Use some Carb cleaner and a stiff wire to clean it. The other pipe runs to

Check for vacuum at idle. If so, replace the part responsible for vacuum to the EGR. If the engine smooths when you unplug the EGR, it's NOT the EGR. If the engine continues to run rough with the EGR hose disconnected, it could be the EGR. Remove it and check it. Hook up a Mityvac and pump it up and see if it holds vacuum. If not, replace it. There should be vacuum at part throttle but not at idle. A broken hose can cause no vacuum. Don't hook up a hose directly to intake vacuum. It'll cause vacuum at idle. A Mityvac can be hooked up to one end and plug the other to see if it holds vacuum, which it should. Block off un-necessary hose connections to test it.

As usual great video. You are amongst the top 5 professionals who also have the gift of teaching. I volunteer at my church's Car Care Ministry. Because of my experience I do most of the diagnostics. We don't charge anything and if the people don't have money for parts we often pay the parts tab. We have 5 lifts! On any given Car Care Saturday we may have 12-15 cars. All I have are basic diag tools eg multimeter, fuel pressure gauge etc. We do have an OTC Evolve scanner which is a blessing but not up date. I would love a scope. We don't have any subscription service either. I put a lot of pressure on myself being sure not to change parts unnecessarily as we have to be good stewards of our funds. Also it's just crazy to throw parts at a car that doesn't need them. As you know without the proper tools the diagnostics takes much longer and much more difficult. I have cancer so I can't work a regular job but I'm blessed to have the privilege and opportunity to help people and use my skills. I was an ASE certified mechanic but had to leave the trade. I was told I had 6 months to live in 01 but I fought back after spending eight years in bed...sorry for the long story but just wanted you to know how many people you help with your videos. I could never do what I am doing without studying the top You Tube teachers. Just like to add, if anyone would be interested in donating or loaning a scanner or scope or any tools it would be a great help and it would be tax deductible. We were recently on USA today and had 7 million views! Many people donated cars which we fix up and give away. We donated 27 cars last year. There is always a need for Diagnostics.

I checked MAP sensor measure voltage etc, it’s functioning properly because voltage fluctuate with different amount of vacuum. The only thing I can think of is computer is somehow causing the trouble code maybe it needs update or even another computer. I have yet to see a solution Identifix did not help me either. By the way I am not a novice I own a hybrid / EV repair shop so I’m pretty advanced in diagnosis but just this one has been nagging me for a while. Also it’s my personal vehicle with 360k miles on it

Hello, I just subscribed to your channel. I have a 98 Dodge Grand Caravan 3.8L, and it's that time of year again. "Smog Test". My check engine light is on, it has a rough idle, and my gas millage sucks. Code P0401. My mechanic suggest I pass my test under the radar, as apposed to cleaning out, or changing the EGR valve or possibly worn out vacum hose. Oh, this is the kicker, sometimes my dash gadgets don't light up, and the car will turn over, then immediately turns off. I hit the top of the dash board before turning the key, this worked a few times; but lately, I have to call a tow or leave it there until the next day, then it starts up. Could all of this be due to my EGR valve or do I need to replace the ECM Control Module? What are your thoughts?

"A gas has mass therefore it still takes up space"? I think we went to different schools. Mass does not equal volume. I think you meant to say that it has volume, not mass. It is the volume of inert exhaust gasses being recirculated by the EGR valve that lowers the percentage of oxygen in the combustion chamber thereby reducing the temperature of the resultant burn. Helpful video but a little bit misleading with your confusion about mass and volume of a gas.

On this engine the computer looks at the Manifold Absolute Pressure sensor for a 1 kilopascal pressure drop when the EGR is activated. On a hunch I removed the MAP sensor and cleaned the manifold port under it with spray carb cleaner with and without the engine running. Until I did this the flow code always came back. Cleared the code and happily it has not returned. EGR flow problems can be a challenge.
