Throttle position sensor Replace

[CameronDavidson]

Hello all,

I have had a good look through the treads, and can't find any help, so I wondered if anyone had an idea of how to replace the Throttle position sensor on a n52 2.5si engine?
I have a slight hesitation on the throttle pedal when coming off and back on again at around 2.5k revs, and I have replaced the Coil packs/plugs/Solenoids, so I am working down the list!

Any help/pictures would be awesome.

Thanks.
Cameron.

Hmmm interesting. I’m not sure it even has one to be honest as the n52 does not have a conventional throttle. The accelerator pedal is a pot but never heard of them going wrong. Other than that, throttle is controlled by valve lift which is done by the Valvetronic motor / eccentric shaft sensor. But your symptoms don’t really fit with a fault there. Sounds more like DISA valve related as that is about the rpm where they change over.
