    Hello all,

    Recent did another engine out and was coming back with a code. When looking at it, it pointed to the phase senor on to 1-4 side. When i pulled it out, the connector fall apart in my hand. This is apparently normal so i'm looking for replacement.

    The original part number is # 146312.It is discontinued and spare parts have dried up for the most part.That being said, i don't believe that Ferrari made this part. I'm sure that the sensor itself is not made by Ferrari.

    I have found a Bosch 9146108. The connector will fit but not sure about the sensor itself.

    Does anybody have any experiences with swapping this sensor out?

    The 348 wiring guru, @m.stojanovic may be a little busy at the moment, but this is what I have for the 348 2.7 car.

    Can you see the colours of the wires on the car side of the plug? Or is the harness sealed?

    pin 1 pink/black goes to red wire
    pin 2 pink wire goes to green wire
    pin 3 black wire goes to black wire.

    Probaby best to confirm with a multimeter:

    You should be able to see 12 volts on the pink wire (with a voltmeter with the ignition turned on) and an earth (with an ohmmeter) on the black wire.

    That's exactly what i need. The connect from Hall is a female, so i ordered on offline. Its a bosch EV1 3 pole connector.

    Thanks!!

    As a temporary repair of my desintegrated Cam Sensor connector, I cut-off the connector from a used crank sensor and soldered it on. It worked very well and could have been a permanent solution but I later moved it to spares and installed a new one.
