Right Bank Speed Sensor
Bank? A bank usually refers to the 02 sensor side, e/g Bank 1 sensor 2. or Bank 2 sensor 1.
The speed sensor relates to the individual ABS sensors on each wheel.
Does the car drive funny? Do all the wheels match? Is there any hesitation under load?
Too many unknowns and that code he gave you P1076 is not a recognised SD2/3 code it is a Generic OBD code from what I can see.

My generic OBD reader gives the P1076 code with an unknown definition. The SD3 gave the same code of course with the definition I listed above. I also found a reference online to that same right bank speed sensor (as well as some other definitions which did not apply to Mseratis)
There is some lugging in low rpm 1st and second under load (like uphill). Not all the time. But it happens fairly frequently.
Wheels have been changed to 20" rims. I measured tire circumferences and the rears are a bit larger than fronts. I am suspect of this but haven't been able to confirm that this could cause the problem before I go changing wheels or tires.
One other possible issue: The transmission may have been replaced and I have been unable to verify what year the F1 is. If it was replaced with an '06, I was told there could be a gear ratio difference that may possibly affect the speed sensors? Code on trans. is "214798" above "00626 5T" Can anyone verify year from this?
From your questions Contigo, it sounds like you may have helpful knowledge about what could possibly cause this. I appreciate your help.

OK - first caveat is that I am used to working on Ferraris however the systems are pretty much identical so I may be able to assist.
I don't have P1076 listed as a manufacturers code from the engine ECU. However, you can get a similarly described code out of the ABS ECU: C1200 or C1201. The desciptions are:
C1200: Error detected when there is no speed signal from the front right toothed wheel sensor. Caused by: fault in the sensor or open circuit on the connection between the ECU and the sensor. The error is memorised in the historical records when the conditions are restored
C1201: Error detected when the speed signal from the front right toothed wheel sensor is unstable or not constant. If the signal is intermittent, the ECU switches the fault lamp on when a speed of over 12km/h is reached. The sensor is faulty or is not operating correctly
Did you get the SD3 to read the errors on the ABS ECU? Whilst you're connected check the speed reading from the wheel whilst driving.

Talked to another Mase specialist. Suggested cleaning the MAF sensor as he's seen those cause all sorts of weird issues. I did that and still the CEL came back on. My next step is to get a set of rear tires that keep the relative front-to-rear size-increase percentage the same as the OEM wheels - or at least closer than the 3.1% difference I now have. OEM difference is 1.1% larger in rear
Interesting, after clearing the code this last time, I did notice that after a short drive, there was (1) P1076 code on the scanner but no CEL yet. Then another short drive and the CEL came back on with the second P1076 code. (There have always been two each time I do this)
Not sure the different gear ratios in this 06 tranny would cause the CEL issue. (And no the Gearbox ECU was not changed with the tranny change)
I'm also doing basic resistance tests on the wheel sensors to see if there is an obvious problem. I did notice that the front right rectangular sensor that sits on the metal bracket mounted to the backside of the hub appears to have been changed out (slightly longer wire and it was routed differently) and it's resistance is very slightly different than the left wheel.
I don't have easy access to the SD3 to do a drive test. That's 3 hours away + $$$

I do not have access to my list of Maserati codes will try to look it up tonight, but, i would have thought the SD3 would have been able to define the problem a little better than that? speed sensors are wheel sensors on the ABS or there is a crank speed sensor on the pulley wheel, and a road speed sensor on the gearbox final drive, but these are all common to both banks so seems unlikely, does the car have CAM position sensors? would these be described as speed sensors? this is an odd code description, the use of the word bank suggests one half of the engine, since that is the normal terminology for one bank of four cylinders, but there is not a unique speed sensor for each bank, so the code itself is ambiguous, which makes me surprised that this is actually what the SD3 reported?
Well, I found some lower profile tires for my aftermarket 20" rims which brought the proportional difference between front and rears closer to OEM.
That didn't stop the code from coming back on.
I scored a set of OEM wheels but when I went to put them on, I found out the lugs that are on the aftermarket wheels are much shorter than OEM so now I need a set of lugs to in order to test with those wheels. As soon as I get lugs I will try that.
If that doesn't work, I found a gearbox with the proper ratios that I can swap to get it all back to stock. I hope I don't have to go that route but I've got to get this figured out.
I am surprised as well about the SD3 being so vague about this P1076. It is leading me to wonder whether the actual culprit is in fact the '06 gearbox. That would be a very uncommon situation to come across so maybe that's why nobody has heard of that code.
Again, any help is much appreciated.

Well OEM wheels didn't do it. Code still came back on.
Anyone know if the speed sensor on the gearbox is the same on '05 and '06?
Anyone know if the gears out of a cambiocorsa F1 will drop right into an '06 QP F1 case? The one I found has the right gears in it but the input and/or outputs are different.
