THANKS for sharing this with us. We struggle every day with this parts game.Wish our customers really knew how hard we all work to repair their rolling computers

[@VashthStampeede]

I am not surprised by anything FoMoCo does. In the seventies, a 1972 Ford Econoline came into my shop for a tune up. It came back about 2 weeks later with lack of power and misfires. He was irate. Dwell and spark timing was way out of spec. I saw that a lot of the ignition point's rubbing block was worn off inspite of adequate lubrication. Further inspection revealed that the distributor's cam was never polished at the factory and still in sand cast form. He confessed that 2 other shops couldn't tune it either. I called Ford to get a new distributor cam and was told that even though I had the distributor's part number, they wouldn't sell the cam because Ford changes design throughout the model year. I fixed it by installing an aftermarket electronic ignition system that didn't care if the cam was rough. That was my customer for life after that.

[@Discretesignals]

[@tonymorusa7107]

I had the same car with the same issue. The left side rear speed sensor. The owner of the shop got me after market. After some digging I found that the sensor were made in hungry. The ones I got were made in Mexico. I told him we need to get these made in hungry. The customer decided to take to the dealership. Never knew what happened. This confirms my diagnosis. Thank you for showing this video.

[@Mr2004MCSS]

Jake, this is probably your best case study yet. Great job and having the patience to see it through to the end. This case study just proves that you have to really do some in depth research and sometimes guess to get the correct parts. I'm willing to bet most shops and techs would never have figured this one out.

[@JoseSilveira-newhandleforYT]

Bravo, Jake!! Your persistence paid out! Fantastic series of videos! Seems almost criminal that Ford doesn't supply the right sensor by the VIN number - the time and money spent because of that is appalling. This confirms that the correct sensor does talk to the ABS with data packets, while the others just output a square wave. And not a word about it, anywhere!

As a shop manager... I can assure you the fix didn't "pay off"

Excellent work seeing that job through to the end knowing that you can’t recover what you’ve invested! But to then make the time to hook up the scope and find the answer after you knew it was repaired? Beyond excellence. Makes you wonder if we’re a little twisted when the satisfaction of the fix is worth more than the money made.

Fantastic series! As always, you do an outstanding job of diagnosing & sharing your findings with us! You mentioned recouping some of your lost time. I bill for all my time in cases like this. It's not your fault that mis-information made the diagnostic process take longer. The customer should pay for your time as you are a diagnostic/electrical specialist. I explain this to my shops & insurance companies.

I still billed most of it but when I have a customer that is as easy going as this one I tend to be easier on the bill. Hopefully the videos will make up for the rest.

[@D-Marq88]

I’ve been tenured with JLR and with Ford. It is quite surprising with Fords market size as a brand, that they can have so many part incompatibilities by vin. I have ran into this with many of their sensors especially MAP sensors. Loved the comment sections quick jump in the last videos to “I told you it was an incorrect CCF” haha I will tell you though that the verified data and good known in the very end of the video is extremely valuable. Thank you for taking the time to make these videos.

[@markwatson9816]

Jake First - AWESOME series of videos and congratulations on figuring it out! Really amazing work and the sign of a master diagnostician! Second - I'm one of those damn engineers that mechanics complain about ;-). Since my area is electronics I've spent a lot of time digging through scope traces I have this observation. I noticed on the scope traces an interesting thing. At these time stamps there's another very slight signal anomaly that seems to be on both channels: Time stamp number of time intervals from the left side 22:35 +1 - I had to pause twice to get to a 2nd frame with the same time stamp 22:40 +2 - same as above 23:05 +2 - after you paused the display at about 23:01, the signal I'm mentioning is 5 time frames to the left of the blue "data packet" For a time length that's about the same as the "data packet" on the blue channel there's what looks like the same time length "noise" particularly on the red channel. I'm wondering if the ABS module tries to pull down the signal and on the blue channel it can, so it accepts the sensor as being correct. On the red channel when it tries to pull it down since the signal doesn't pull down it doesn't accept it as the correct sensor and that's why the error is shown. Alternatively, the sensor sends this packet and the "noise" I noticed is really noise ;-). Question: Did you time the frequency of the "data packets" to see if they're regular? Thanks again for an awesome set of videos about this puzzle. Mark

[@autodiagyt]

I didn't go into that much but I think the noise was ignition related.

[@richardcranium5839]

notice the shape of the signals. the red trace pulls down stays down then goes back up. where the blue trace only reports the start and finish of the segment.

[@richardcranium5839]

or is it reading the space in between segments?

[@KB-rd1ej]

what is the difference in ohms of the sensors, as a ford tech of over 30 yrs i always made comparisons and kept notes. I'm retired now thank god. I feel your pain!

[@autodiagyt]

The only time I look at ohms is a VR sensor. These MR sensors are digital so you are not seeing anything definitive with a meter. I’ve seen some MR sensors read OL but work perfectly, they just have millions of ohms of resistance because it’s a power supplied to a power converter to a micro processor.

This is where dealership ties really help. Props to you, aint no service data for that type of work! How did you find out that the hub came with a new wheel speed sensor? Makes you wonder whoever changed those hubs had to have that same issue and because they didnt do anything about it, they just punted the car. Think about doing the hubs on that car and then discovering that issue? Its a super easy problem to solve. The shop punted the car and you were left to pick those pieces!

[@rivertroller]

[@bobcombs7138]

That was a great series Jake! I'm wondering if this could be a SENT sensor. Instead of the usual signals, it sends data to the module. Talks to the module reporting information about whatever the sensor is designed to monitor. I do know they are starting to use them in some European vehicles.

[@autodiagyt]

After seeing the scope pattern it seems to me it's a type of data packet somehow so pretty similar to a SENT

[@BehindTheCounter_TFSO]

I remember Keith from LT1 having a similar problem a couple of months ago, but this was with a cam sensor on a Cadillac with a V6. GM told their dealers that if they did not have this specific number in stock, it could be superseded to another part number instead. In my opinion, I don’t think they knew what the difference was; they probably looked at it as a way of saving money on inventory. This is typically seen in the aftermarket, where they attempt to consolidate part numbers.

[@ghostlegz]

jake man that rabbit hole was deep. the scan tool was not lying, it said that was the wrong sensor. man its tough to know when to trust your scan tool and when not to. but in this case if you had you still would have been in hot water as ford screwed the techs with this crazy sensor and not list it as a single part number and have it only as part of the whole hub assembly. Man good detective work to hunt this one down.

[@paulpyke7935]

Great video!!! Thanks for sharing all that informations. I was wondering would the signal from front sensor be the same like this good one from rear, maybe it would help diagose it little faster.

[@autodiagyt]

The front sensors use a standard MR signal just like the Red trace in the scope capture.

[@jerstuube]

That was a brutal job! thanks for sharing. One question, was the scope lead hooked up to the "hi" or "lo" side of sensor in order to get the wave form?

[@autodiagyt]

Both leads connected. Same as in part 1

[@nissanneal]

I knew it was going to be a simple fix to a difficult problem.

[@mike-yp1uk]

I had one come in and both rear didn't work but I had a mini signal on the scope. The fix was water in a rear connector. Blew it out with some WD-40 and it came back to life

[@Arphand]

I had known for the last year or so that BMW uses sensors that send a data packet to determine speed and direction, but I had no idea Ford was using it, let alone on a Focus from 11 years ago! Lab scope everything, and assume nothing.

[@autodiagyt]

Isn’t that crazy!

[@AAB371]

This is diagnostic gold

[@ktcarroll4723]

I had a flash back to Pine Hollow having a timing code with all new parts and 1 phaser was a little off on the timing mark the pico showed it but it was actually a little luck and knowledge he found it

[@ktcarroll4723]

I forgot to say the timing marks aligned but the camshaft lobes were off because of it being the wrong phaser

[@ColeTanner88]

So I was partially correct in my thinking on my part 2 comment. The module is seeing not only the voltage level, but the lack of that "data packet" intermittently pulling the voltage down slightly. Those are wildy different signals when moving. Is there some sort of microprocessor in the correct sensor that's actually sending some sort of data packet? I'm not understanding how the module is interpreting the data... Great case study, really appreciate you posting this and your determination in seeing this car through to the end.

[@autodiagyt]

Yes it has a micro in it. Pretty crazy stuff

[@ColeTanner88]

@autodiagyt that is nuts. It's crazy how technology is moving on modern vehicles these days. It's hard to keep up! Consumers always arguing about price, diagnostic charges, etc and have no idea what it takes to fix their vehicles. I think we've done a poor job of educating the public on that front. It's getting better, but still a long way off.

[@NoName-yr1jv]

Well done 👍

[@totypme]

Such determination. did you check the resistance or impedance of the unit.

[@autodiagyt]

Digital sensors don’t give good results. Older VR sensors will because they are a coil of wire but anything square wave you are reading the resistance of a power converter and other circuitry.

[@cullenmiller8170]

Great series and case study. I guess the lesson learned is that you can’t even trust the OEM parts anymore. The other thing is keep the broken parts until you a 100% sure the car is fixed. The problem for you is that by the time you get the car it has been through multiple shops and you never fully know the problems that have been inflicted on the car.

[@mike-s8n8y]

Man that was a good one ,content gold for you , was that stupid fast waveform not coming from the module as a confirm signal that the wrong sensors would not allow on the signal , seems odd a sensor sending that out ,

[@autodiagyt]

It’s like a one way communication similar to a SENT module I believe

[@mike-s8n8y]

@@autodiagyt Thanks for reply , i have never seen this on a wheel speed signal , learn something new all the time ,cheers

[@10100rsn]

The hall-effect sensor inside of those Ford sensors probably has programming that is different between them. Yes, some hall-effect sensors only need 1-wire to communicate digital information and have programmability that needs to be set for your application. The 1-wire protocol similar to I2C but with one-wire. That programmable data is usually dealing with magnetic sensitivity, magnetic orientation and a *_programmable identification number_* that can be read by the software in the module. If the sensitivity or orientation settings are incorrect for that hub it might just not detect the rotation, _but if the ID is not recognized by the software in the ABS module_ then who knows what it will do. The ABS modules were probably getting programmed with newer firmware that didn't include the other IDs for those parts, so when you updated the firmware it no longer recognized the other parts as valid and usable. IMO, it was an ABS software issue. Ford can fix this with software but probably won't. The 1-wire protocol is well documented so if you can figure out the exact IC inside the plastic molded Ford sensors and get their IDs then someone can probably work out how to reprogram the ID in the sensors with an Arduino, too. Would just need to know the IC part number and work out a circuit to communicate with it at 12v... Edit: Some of the hall-effect sensors also have a configurable output mode.

[@10100rsn]

Yeah, one sensor is probably digital and the other probably set to pulse output. This makes sense to me.

The one it's happy with must have a chip inside that is doing processing and reporting the data back, so one is an 'active' sensor, whereas the other one is a 'dumb' sensor where all the processing is done on the main module.
