p0238, turbo boost pressure location

[Kacmotus]

ive recently made, i say, an upgrade to my car, from 1.0 petrol to 1.4 turbo diesel, now im having issues with the turbo sensor, i feel as if it not kicking properly, acceleration is fine but OBD pops up with p0238 error code
i would like someone to help me locate, because i know a garage would charge a lot for a very simple thing, unless it looks to be a more rigourous checkover for it
ive looked at many youtube guides but cant seem to locate none the less,
my garage pointed at the MAF sensor, but since then i have changed it myself, cleard obd yet still pops up with same problem

also i have some oil leaks, but cant decided what it could

I works guess the boost sensor is the thing with a green electrical connector on the elbow to the left of the Duratorq TDCi box.

ok thanks, is there a way to clean it out? because whenever i do clear obd it does kinda stay off, but does return, thanks in advance

It’s probably caked with oil and soot from the turbo. I think brake parts cleaner spray is safe but I don’t know for sure. That elbow sees pressure so oil and soot might get into the sensor where you can’t clean.
