  • S54 Throttle Position Sensor values???

    Hi all,

    I've been scouring the web for the resistance values I should be getting on my TPS to make sure they are correct but to no avail. I am getting the following (with 3 pin electrical connector removed and measuring with an ohmeter direct on the TPS, pin 1 at top):





    Pins 1-3: Throttle closed = 4K Throttle fully open = 4K
    Pins 2-3: Throttle closed = 1K2 rising linearly to 2K7 at Throttle fully open
    Pins 1-2: Throttle closed = 4K8 falling linearly to 3K3 at Throttle fully open

    Can anybody confirm if this is correct??

      Thanks Simon - you're an absolute star 8)

      A bit puzzling though - nothing like the kind of resistance readings I'm getting. I wonder if the S50 engine had a different TPS to the S54?

        Nope, same one, part # 13631402143.

        Interestingly, the BMW parts list refers to it as a "4Kohm". The above info' is from Autodata.

            If anybody does get a couple of minutes spare at the weekend and has a multimeter lying around, I'd really like to know what resistance they get betwen the pins with the throttle closed.

            It's very simple to do - just unclip the electrical connector.

            Thanks 8)
