47 years in this business, I'm a tuner, a very experienced technician, and I'm at least a hundred training courses in on engine management. This course is an excellent training course in the operation of the fuel trim system. I actually didn't learn new things but again, nobody is born with this knowledge. I'm sending my technicians a link to this video because I cannot see into their heads and know exactly how much of an understanding that they have about this subject. I liked the way that Dan stayed away from brand differences, particular engine differences, and other variables and concentrated solely on the fuel trim system in general. Great job! I highly appreciate you giving this knowledge to bring technicians up to speed on these systems that have been in place for over thirty years and are in use on almost every vehicle on the road today.

ScannerDanner You really do an amazing job. I myself am Master ASE Certified, and as we all know sometimes we neglect to K.I.S.S, which was my case today with a 98 Saturn 1.9l. Came in, no check engine light, rough idle, bad gas mileage, etc. STFT was @ -25% to -30% and LTFT was @ +9.4%. Realizing it was running rich based on the STFT values, I went ahead and pulled the booster vacuum hose to create an artificial LEAN condition. STFT didn't change, nor did LTFT. I thought, hmm. I checked Fuel Press, spark, etc. O2 upstream was moving accordingly high/low, so I was scratching my head for a bit. I watched this video as a refresher, and as soon as you said "reset the ECM for a relearn" that little light bulb went off, and the "DOH" moment arose. I did exactly that and a 3 key cycle test drive for a relearn, and bingo, my values are now back in spec. Looks like the previous shop replaced the vacuum booster line, and neglected to clear and relearn. Keep up the great work man!

Someone could say it's pretty obvious what I'm saying, but I've known A LOT of teachers that lack this kind of pedagogical way of teaching.Not only that, you're showing all of this by free. THANKS!!!

Agree with your approach completely as far as waiting on the cat. code. Check the PCV hose under the intake for a crack. This is very common on the 2.0 engines, not sure about the 1.6. I have seen also on Fords the stem area of the EGR worn out. When I changed my EGR on my explorer I had a 10% improvement in my LTFT. They all leak a little in this area though. Even the new ones.

You do such a great job explaining this. I own a 2008 Toyota Camry 4cyl With no problems until it developed the fabled oil consumption problem. It didn't throw any codes... just burned one quart oil per thousand miles. Well, to Toyota's credit they wrote me and told me to bring it in because they had identified that model was having that problem. I had gone to the dealer and they had pleaded ignorance. Long story short, they replaced all four of my cylinders. 5 miles after leaving the dealer's service facility the car through a PO171 code and acted like it was coughing up blood. I hurried back to the dealer's but they had closed. Had to drive the car over the weekend and it got better and better.... But the PO171 code stayed. Well the dealer at their own expense replaced the intake head gasket, checked the fuel pressure, said they found a crack in the PCV hose, added a can of 44K and finally put in a A/F sensor (at my expense) based on a P2238 code. None of these worked to stop the PO171 code. Additionally, soon after occasionally the car developed a condition in which it would not start after being driven about 20 miles and if I would stop it would not start. On these occasions I found if I waited 20 minutes or so the car would start. However, it would start if I sprayed some starter fluid in the intake. That was three visits to the dealer at their expense and they could not find the problem. Otherwise the car drives fine. So I'm left with trying to find a problem myself or as they said wait until it just want start. I have waited a year. I have looked at your and other videos, Google articles, etc. I have changed spark plugs, air filter and checked for air box leaks. The car is too good to be just junked even though it has 280,000 miles. After all it is a Toyota. I have had no problems with it until the oil problem. It has stumped the dealer and me. But, I am trying to diagnose some things. I bought a scanner. I am not mechanic. Bought a generic live data/1 parameter graphing scanner out of desperation because dealer could not find the problem. At idle....the scanner said; 2008 Toyota 4cyl 2.4 LXE @ 900 RPM right after start up 122 degrees F coolant temp STFT -3.1% LTFT +35 to 44% IAT 57 degrees MAF ???? CLoop except when snapped WOT the trottle when it temp went to OLoop After driving 10 miles: 670 RPM in idle CLoop 201 degrees F STFT +4.7 to +10.2% LTFT +34.4 to 44.5 % IAT 113 MAF .32 5.02 (very varyable) O2SB1S1 -0.01 ma Cat Te11 635 degrees F Cat Te12 341 F LAMBDA B1S1 1.000 BARO 30 (never varies a lick from this) At this point I cut it off. Again it would not start!!! Tried starter fluid still no start. Waited 20 or 30 minutes started up without the starter fluid. Acts just like an old car I had with a vapor lock problem.

THAT WAS an EXCELLENT Theory of Operation followed by actual test of a vacuum leak, then an extra fuel injestion (not injection) and how the system can self correct. What you said about having LTFT positive 30% and STFT-30% can be confusing, but showing +30 and subtract (-)30 = "0". It becomes a little more simple at that point. Then it's up to the system to self correct, or delete the codes and wipe clean the fuel trim memory, then observe it with the engine running. WOW!

Paul... Your knowledge of engine diagnostics has been very helpful to me. Earlier today I bought a scan tool that gives me more comprehensive diagnosis. And I've discovered about fuel trim issues which has determined of my engine running too lean. Just to give an example of the fuel trim readings. Long term is reading between 20 - 25%. And the short term is reading at 15 - 20%. Not to mention the idle is a bit rough. Anyway, I just want to give you thumbs up.

Bought a beater of a KIA sportage for $1000 that somebody basically beat up, and threw away. Leaves inside the valve cover. Failed smog twice. Bought unnecessary parts for it,and then found the secret hidden vacuum port, and plugged it. Bought an OBD ll scanner, and watched a gang of your educational videos, and have been able to diagnose, and monitor the vehicle. STFT modulates at both 0.8 and 1.6 on both sides, and the LTFT is at 2.3. Idles great, and performs really good. Thank you Scanner Danner. (Think I'll make a smoker just for fun).

I help out at an auto parts store and lots of customers buy O2 sensors because the scan tool says so and it's normal for them to come back and say the sensor we sold were defective because the light is still on. I try to explain O2 readings to customers as a rich oxygen level or a lean oxygen level.

To answer your question,rich condition(excessive HC lack of O2) without the exhaust leak does not damage the cat,but put it to sleep.Therefore,your tailpipe CO and HC will increase and NOX will decrease.As soon as the rich condition is repaired ,the cat starts working again. What damages the cat is HC+O2 (lean misfire,low compression.etc) because it burns inside the cat and melts the substrates. But like Paul mentioned a rich code for OBD2 will set at %15. Thank you

Yes Scanner Danner does show Eric up on sensor diagnosis. Eric is still experiened though. I get the impression that he sees the data, has an impression of what's wrong, and at least on camera he's usually right. He's happy to show his mistakes like Danny is because it's fun and we learn from going in the wrong direction too. What Eric gives us that Danny doesn't is the actual cranking on the car. That does have value too. :) Diagnosis makes me replace the right parts more often. How to crank on a car though makes the actual replacement much faster. Each gentleman is a tool in my knowledge base!
