Error code P1021 and P1059

I would check that the battery is up to snuff. Verify that the voltage doesn't fall below 10v while cranking. You'll need a multimeter with a max/min feature in order to do this.

 

Dear johan6504, I have the same errors, do you have found a solutions? Thak you!

im thinking it doens't involve any parts replacement, but some ground or wiring issue?

 

Hi Marcello, did you find a solution? I have the same errors.

 

I’m thinking this has to do something with the cam sensor. As this is not a wheel speed sensor but engine speed sensor and it differentiate left and right bank. Anyone have any ideas on what to check?

 

The terminology used in the faults is confusing, but suggests that CAN Bus data is missing, not cam data.

The primary CAN Busses are labelled "B" and "C". I've never heard of Bus "A" on the F430. The "B" CAN Bus is communication between the car's computers and the OBD2 port. The "C" CAN Bus takes care of data between computers. e.g. ABS/ASR ECU sends vehicle speed to things like the Engine ECUs, the F1 TCU and the instrument panel on the "C" CAN Bus.

Here's a diagram showing the "C" Can Bus:

The Can Busses are independent, so it's unlikely both have failed. As suggested, it could be a battery voltage problem. If your speedo is working, the ABS/ASR computer is outputting a valid speed signal on the "C" CAN Bus.

 

Thanks Qavion, everything works in my case, I mean the car drives normal, Speedo works fine.
I’m speculating the speed signal here is referring to cam sensor, or vtc related not wheel speed sensor as it refers independently on each bank of engine.

Wheel speed sensor usually referred as wheel speed, as it has nothing to do with engine but ABS system.

I could be wrong as this is Ferrari after all. But that’s what I usually encounter when working on other cars.

 

The WSM does say that "car speed" is supplied to the Bosch ECU.

Ref page C1.01.

I'm not sure what it is used for on the F430, but on the 360...

Well color me confused. I wish people that solved the issue can share what’s the solution is

 

Did anyone have a solution to this? I have P1012 and P1016… “unknown trouble code.”

 

hi, have you found the source of the problem on P1016? I also have the same problem on a Ferrari 599GTB

 

There are a couple sensors that plug into the valve cover gasket, I forget what they all are and each do, but if they are loose, have a bad connection, or are failing, they throw these codes. When I’m back by my computer I’ll look at the diagram and get back to you. I’m traveling and will need WiFi.

 

Skywhale, Thank you, I'm waiting for further information

 

I think I remember - “phase sensors.” Look at the Left and right valve cover diagrams on any of the parts sites and find phase sensors. Then I’d check to see if yours are tightly secured. I resolved mine by pulling them out, spraying some electronic cleaner on them, then secure down.

 

What do you mean, Angolar speed sensor? see diagram no 17

I can’t see the numbers clearly on that image, but the ones you have highlighted in yellow. Those are what caused my issue. Ricami had them called “phase sensors.” Mine came up after doing a valve cover gasket change. Just taking them out, making sure they were clean and then tightly secured again solved.

 

OK, I'll try checking the socket connection and the tightness of the bolts, thanks

 

Yeah, and I’d check the wires themselves. Could be oil on the wires, burns, etc. Mine didn’t, but like the variator solenoid problems, I don’t see why that couldn’t happen.
