F8 CEL - P155D

I’ve been getting this CEL intermittently “P15DD” is the code. The car is normal with no hiccups in power when it comes on although the very first time a few weeks ago when it came on the car wouldn’t go past 4K RPMs.

It’s completely random in timing and I’m stumped as to what specifically the code is for as there isn’t any information on it online. Are any of you F chatters familiar with this specific code?

 

Is your car modified

 

Should be wheel speed sensor…a call to service will detail. Check battery. I threw at least four codes and it was battery related (on my Pista)

 

Novitec exhaust / spacers / sport springs.

 

What scanner are you using? I get a few cel on my f8 with the Novitec exhaust but could not find a scanner that would work. Please let me know thanks

Used the AP200 but also the shop that did the install had a fancy scanner and both results yielded same code. It's apparently a wheel speed sensor. I'm getting it checked out Thursday. I'll keep you posted.

 

To add to this likely being the wheel speed sensor I was also on 2 separate occasions getting a TPMS error indicator which I suspect is related to this CEL.

 

It's probably the spacers.

 

I didn’t want to say it as those with mod care always get so defensive but @radlu is probably correct and my thinking exactly. Hopefully your dealer did the mods and will convince Ferrari NA to cover under warranty. If not however, I assume they can afford to pay for the repair which is probably not a big deal…

 

Spacers have nothing to do with a wheel speed sensor. The TPMS error was coming and going prior to spacers being put on and my service advisor also stated spacers likely have no correlation. It’s getting checked out now and I’ll circle back with update once taken care of.

 

My point made about those who mod their car. Lo

if you know so much why post here asking for help then.?? SMH

 

Sorry didn't mean to come across the wrong way

 

Have you been able to figure this out?

 

O2 sensor related. Shop that did the Novitec install is checking it out Wednesday.

 

Sorry to hear but again point made being doing these mods can lead to issues no matter how safe the shops tell you they are That said o2 sensor failure is not terribly uncommon so what did your dealer say about switching it out? If they have the parts it can usually be swapped in less than 30 min

 

I don't think the sensor itself is bad, shop mentioned checking out the OPF connections. I suspect the sensor is looking for GPF related settings which aren't present. I agree it is unfortunate the lengths we have to do aftermarket mods just get the car to sound decent. It's perfect otherwise but the OEM exhaust is way too quiet.

 

Turns out there was a kinked hose that was connected to Novitec exhaust. Shop that did install fixed and car feels and sounds insane now. Did probably a 100 miles on it and it's been flawless.
