348 ECU codes

These are the little gremlins that pop up on cars that sat unused for extended periods as yours did. I think your got 1 or 2 new fuel pumps just before you bought it. Factor in the fact that you got a smoking good deal on it and in short order you'll have it sorted out and in tip top shape. You soon learn a lot of what goes wrong on these cars is not that expensive to repair and even the weekend mechanic can do most of it. When crap goes wrong just take a deep breath and remember how easy it was to fix the last little curve ball your new Italian wife tossed at you and how you fixed it yourself for justa couple bucks.

 

I spoke to Mr Wolf several times since we both had our cars listed on Cars.com at the same time. He used to be on here once in a while as well. Seems like a nice guy with more toys than he could play with so the car just sat unused. Someone showed up to buy the car before you and it wouldn't start due to the fuels pumps. No big deal but it gave the buyer cold feet as they were not Ferrari literate..worked out well for you since it resulted in another price drop..

 

that is awesome that you keep in touch with the seller.

also, good job on replacing the O2 sensors...good luck with the FPR install and keep us posted.

 

that is what makes this an even more enjoyable experience, the fact that a lot of the service can be done with the guidance of the membership here.

good way to look at it....patience is a virtue

 

going to try to use an old post here instead of making a new one.

my 94 348 spider blinked a check engine 1/4 light for abolut 2 seconds yesterday...then it did it again a few times this am... light only stays on for 2 or less seconds. what do i do next?

 

i guess what im wondering is if my next step is to retrieve codes? from ecu's? behind seats from what i read?

 

Yes, retrieve the codes. Move your seats forward, remove the ECU covers, find the little round black (or sometimes red) button beside the ECUs and follow the procedure outlined here: http://www.my348.com/348.html#ECUcodes

At the end of the procedure write-up is a list of what the codes mean.

 

so...anyone done the wire splice version of the bosch o2 sensor...? they have 2 in town and they are only 55 bux...are they touchy to the splice? doesnt look to be too tuff for 40 bux each.

 

I don't know of anyone who has gone the splice route, but I have heard it is possible...but don't take what I "heard", wait for someone who actually did to confirm...by the way, did you pull the codes?

 

I did the splice route on both of my O2 sensors. No problems at all.

 

Does anyone know which order the codes read out? Is the first code that flashes the newest code or the oldest code?

 

The WSM says "in order of priority".

 

Thanks. I wonder if priority was mis-translated or if it really is a priority thing.

Any idea if a bad or disconnected Cat Temp Sensor module will actually cause the CEL to light up versus just storing a code?

 

@m.stojanovic on the 348/355 forum is the best person to ask about this (I always get it wrong). See this post:

https://www.ferrarichat.com/forum/posts/149128134/

but read the whole thread to get some context.

 

I don't understand that, either. I guess all you can do is try it. Miro did specify that his 2.7 car was uncatted, and wasn't sure if that would produce a different result.

"This is on my factory non-CAT 348"

 

Yeah, I unplugged the Cat ECU and cleared the codes. Drive it several times yesterday and the CEL remained off.

On a different topic, when your car is fully warmed up, what is your oil pressure at idle? Mine got pretty low but was middle-ish on the gauge when cold.
