348 Oil Temperature Indicator

By: Nico
I will start with the oil temperature (temp) indicator.
On the 348 sometimes the oil temp indicator does not work anymore and will result in a false reading of the heat or no information at all. To check if it is in fact the oil temp indicator that is damaged you have to go on the back of the car. On the oil tank you have the oil therometor sensor.

Oil Sensor


First step is to fabricate your own ground wire as shown in the photo.

Ground Wire

Take this ground wire and install it from the oil tank to the engine.

That is it, everything is finished! Start your car up to check if it works. For me the fix was OK.
This fix is an official Ferrari method.
