    Does anyone know if bosch part no. 0280122001 (Throttle position sensor) will be ok to use on a 355 5.2? The ferrari part no. is 158170 with bosch part no. 0280122004 stamped on the back.

    Thank you in advance.

    Interchangeable. We've measured the resistances and they seem to match at min/max off the car. I did find some differences between the two part numbers relating to operating range when fitted on my car (The angle is limited by the mechanical throttle linkages). According to the docs, the resistance is linear between max/min, so I don't understand why there were some slight variations.

    In theory, the ECU should compensate for the variations (at least at idle) if the resistance falls within a certain percentage.
