I have worked for Toyota and Honda and both 4 wire planar type widebands work with opposite mA readings. The only way to truly know is to look at the cars technical information. With Toyota's denso type AF+ sits at 3.3V and AF- sits at 2.9V. The difference of 0.4V is lambda 1 which is 0mA. The change in voltage produces the electromotive force that changes the current value. +A = lean and -A = rich. With their denso system in their diesel engine the concept is the same but the voltages are 2.2v AF+ and 1.8V AF-. I will have to dig out my notes on the honda stuff to get the exact numbers. Great video thanks👍

@@ScannerDanner my pleasure! Glad to be able to help. To be honest the technical info that Honda give is not great even on their Maris system. Toyota seems to be a lot more comprehensive but even that has thrown me for a loop on a few occasions. Had a Prius with low voltage codes in a couple of units, techdoc said to change converter with inverter assembly for the particular code. Was intermittent and seemed to be very specific to a particular drive condition. Would happen after the customer overtook another car. Found the main grounds for the control units that showed low voltage codes were shared with the indicator on the left side of the car. As he would use the indicator the voltage would rise on the bad ground enough to flag the codes. Once he cycled the ignition the problem would be gone. Replaced the grounds and the problem never resurfaced. Again all thanks to following your steps👍

@spelunkerd 2 года назад

This video was a real challenge for my dyslexia, I had to pause and watch the first part three times to wrap my head around the numbers. What I hear you saying is what I expected, that when lambda is > 1.0 the sensor is detecting a lean condition, opposite to narrow band where higher voltage numbers mean rich. At the same instant the lambda is +1.5, the current is -0.8, and the two data pids consistently swing in opposite directions, so negative current must be a lean signal back to the PCM in this Honda. That's confusing, but easy enough to remember for Honda. It sounds like it might be easier to remember "Large Lambda Lean" in all cars to recall which way lean pushes lambda. In terms of the response of the PCM, the fuel trim readings are in the SAME direction as a narrow band, ie greater than 1.0 fuel trim means the computer is responding to that lean observation by adding more fuel, like it did with narrow band. In the end, I'll have to play with the scan tool in every car to see how these sensors are calibrated, while driving it rich and lean with snap throttle or induced vac leak. Thanks for the detailed walk through!

@bobflannagan7262 3 года назад

Well well well. That was amazing. After you replaced the sensor and the numbers still weren't right I was hoping you would use the exhaust gas analyzer again for a truth check. I know you didn't need it but would have been interesting and fast to do.

I've used both, and there's a bit of a misconception among the autel fanboys that their scanners are the official "lower priced replacement for snap on scanners". Absolute nonsense. The autel scanners do a lot of things well on certain vehicles, but the exact same can be said for snap on. There are no magic bullets in this business, nor are there any "one size fits all best of the best scanners". It's simply a matter of selecting the best tool at the time for the task at hand.

My 2006 accord had that persistent +12 short fuel trim. Checked O2 sensors, fuel psi, MAF and for leaks. The air pipe from the MAF to the throttle body had small cracks on the bottom where it “accordions “ . Only found it when I removed it to clean the throttle body. Ordered OEM and bam numbers went to +2. Got me thinking. Looked at my 1999 accord, same cracks. Unless you remove the pipe and gently pull it apart and look you will never find them. BTW the 99 has a short term, long term combined of +1.5, with 280k miles I’m fine with that!

Great stuff Dan a lot of learning like always. Hondas do read their perfect fuel trim at 1.0 volt and lambda indicating rich below 1.0 v and lean below 1.0 v.

@bbkmm1 3 года назад

I had exactly the same failure on a 2007 Accord. The code is down stream O2 sensor stuck rich. Lucky I had 2 Accords and swapping the down stream O2 sensors didn't make a difference. Unplugging the upstream sensor did the trick.

In Toyota systems with A/F sensor from Denso, the difference between AF + (3.3V) and AF- (2.9V) is constant = 0.4V. Only the current value changes. Only the current value in [mA] informs about the A/F (or lambda) ratio. Very interesting video Mr. Paul Danner!!

@LAW-fv6ys 2 года назад

Great video! I've learnt Euro and Asian cars need clearing of codes which resets the fuel trims also, after fixing any fault. A test drive also helps to relearn everything back to normal after. However bmw and mini are different resetting/clearing codes doesn't reset learnt adaptions for fuel trims, GDI injectors etc, you need to delete the adaptions with a suitable diagnostic tool or even better inpa or ista SOFTWARE. I've just encountered this on my bmw 325i with gdi after nox sensor failure and 1 piezo injector which was failing lean when hot only. After coding new injector and resting all adaption with inpa I followed the relearn test drive process and now runs perfectly. Bmw also use wide band sensors showing 2volts for lambda 1 stociometric with 3volts being rich and 1volt lean for up stream only and narrow band for downstream 0.45v is perfect 0.9v is rich 0.1 lean.

@lukas181118 3 года назад

Wideband o2 we measured current flow in mA not volts. Positive current -lean condition , negative rich . 0 current means afr14.7 or lambda 1 .

@ScannerDanner 3 года назад

Positive current on this one was a rich signal. Also watch when the system was in decel fuel cut mode. The sensor went even more negative

@ScannerDanner 3 года назад

watch at 35:53 when I had the MAF unplugged for the best view of this, both downstream and upstream sensors are full rich in this moment (new upstream sensor) Lambda is opposite, but this is just a calculated number anyway. Lambda = 1.0 and numbers below are a rich indication and numbers above are a lean indication

I did a toyota in which unplugging the battery did the fuel trim reset, the fuel regulator was allowing about 5psi extra pressure than spec and somehow the lambda sensor was reading lean, and even with a new sensor it did the same, like if the amount of fuel was so much that it messed up the reading, anyway, the original sensor was dead and changing the fuel regulator and resetting the fuel trims repaired the fault.

@ScannerDanner- Happy New Year Paul. Well , I think this might throw my theory out the window at wide open throttle, watching the voltage on a wide band sensor should decrease slowly over the time the vehicle is driven at wide open throttle , then increase when foot is taken off the gas indicating the wide band is operating correctly. Thought I had these wide band sensors figured out, perhaps not!😂

@ScannerDanner Год назад

Just remember that wideband sensors and how the manufacturer displays the data for them, are not all the same! The signals can be opposite of what you think or of what you've seen before. I do believe that when the actual milliamp numbers are given, that positive is lean and negative is rich, just like we saw here. But when voltage is given, this is a processed valve and the numbers can be whatever the manufacturer wants and they are definitely not all the same.

+-5 can be mass airflow dirty, others should not him, or the acceptable error from old sensors. +6 to +20 pumping case can be fuel regulator or fuel pump (pressure check important - use manufacture data documents/ Alldata), -5 to -20 can be injector leak or regulator too high (pressure check important). over +20 need check by smoking test (maybe gas cap, Evap system, brake booster leak...) or just lock all split air hose, it will easily figure out. Data memory is never needed to reset due to supper fast PCM re-action. if the memory of long trim is +49 and all problems are solved, the -48/-49 should appear immediately in short trim. So confident with what you see on real-time data. PCM is never wrong but sensors can lie. DIY doesn`t have too many bucks to change and to try on everything to tell which was wrong. So do the smart way with correct logic and correct analysis will save a lot.

ScannerDanner i have 2 dodge calibers different years "2007 and 2012" but both have the P0420 code and both have bad Catalytic Converter i did the same as you i replaced both o2 sensors on both cars and both smells like rotten eggs.. long story short i don't have "$1,018 each" for the catalytic converters.

@ScannerDanner 3 года назад

Rotten egg smell is NOT from a bad cat. It is from a bad mixture going into a cat. What are your fuel trim numbers?

@@ScannerDanner well i can't tell you on the 2007 it's off the road for some time till i can get other things fixed but the 2012 is the car i'm driving when it showed the engine light it had a s.t. of 1.3 and l.t. of 3.9 but i had to bust the Catalytic Converters on both and get 2 new exhaust manifolds for both the Catalytic Converters where stopped up and cracked them.. they got very hot

Test drive the car full throttle uphill if possible. Then recheck the rear sensor.

@JimmyMakingitwork 3 года назад

In the flat rate world, once I saw the rich rear reading and lean front, while smelling rich condition…i’d unplug the front sensor or induce a vacuum leak to test next. They are usually asking me how long before I can look at 3 more cars….:).

@ScannerDanner 3 года назад

agree, in the flat rate world and even in my brothers shop, this thing is getting a new AF sensor based on just a few checks with scan data. When we started, my brother had already ordered a sensor. I just used this opportunity to go over some things with you guys

gas analyser after shot, please please, please! you have it on the table, why not take the readings after_????

@Sean_Diagnostics Год назад

this is really confusing me, I always learned minus current is rich condition. But from what i get from the video honda is using minus for lean, because if you force lean condition during the test drive it goes minus 1.6

@ScannerDanner Год назад

Yes sir. They do not all operate the same

@Sean_Diagnostics Год назад

@@ScannerDanner Thanks for answering! Makes me feel more confident diagnosis wideband O2 sensor. Just a quick question if you run the O2 sensor rich you should read a high number in the rich range? Because i was not confident enough calling the sensor because it stayed close to 0mA on WOT in second gear, because I thought wideband is able to keep lamda close to 1 during all operatons of the engine

@ScannerDanner Год назад

@@Sean_Diagnostics when I test these, I'll do both forced rich and lean conditions and watch for opposite numbers. For the rich side, a wot run and for the lean side a high rpm decel event (injector cut mode). No different whatsoever for how I test a narrow band O2. I just want to see both extremes. Make sense?

What autel scanner is that your using ?

@Sophie333C Год назад

Why are you not using the equivalence ratio?

@ScannerDanner Год назад

If the sensor is wigged out, how is a data pid that is a mathematical calculation based on that sensor going to help me any further? Serious question. Maybe I just don't know how to use it as I should be?

@Sophie333C Год назад

@@ScannerDanner if equivalence ratio greater than 1 you have a lean condition, less than 1 you have a rich condition!

@ScannerDanner Год назад

@@Sophie333C but if the sensor is skewed, that data PID will be also, so I guess I don't really see this being a major value to us in this case. Thanks!

@guccimane5752 3 года назад

I thought for a/f sensors negative numbers mean rich?

@ScannerDanner 3 года назад

There is no set rule for that unfortunately. It is opposite on this model.

My wife's 07 Accord gets a PO420 code that will cause the engine light to come on for a couple of days and then go away, for weeks and then come back for another couple of days and then go away again for weeks or months, no other codes just the PO420, any ideas?

@ScannerDanner 3 года назад

Yep, you need a cat Make sure you do not have any exhaust leaks and fuel trims are normal and no other codes. Use a factory replacement ONLY! Aftermarket cats will set this same code again in just a few short months

@rick343 3 года назад

@@ScannerDanner Question, if I took it off and hollowed out the inside and put it back on, will it throw a code? We use to do that in the early 80's when they would clog and cause loss of engine power. The wife's car is running perfect, can I use a temp sensor gun and keep a check on how hot the pipe is before and after the cat to see if it's getting worse? Just wondering.

@christiandiaz7422 3 года назад

Hey Paul I have a question for you. On material that I have read and on some of your case studies says that negative current is rich and positive current means lean but in your scan tool you it appears only negative current flow, why does that happens?

It is on SOME, not all my friend. Read the pinned comment from a friend, right here in this comments section. Thanks!
