The sensors is in the intake for temperature and pressure, I believe it's called MAP for manifold absolute pressure, but on this car it also does temperature. It can get sooted up and cause issues. One of mine had a history of an occasional P2598.. but hasn't come back since I cleaned that sensor. If I can find that thread I'll link it here for you.Last month Racecar had thrown all the codes (P2098, 22099, Turbo Boost Undercharge?) and it was a small hole in a vacuum line. That was fixed.
Last night the only code showing was P2598 (well this is what the local parts store told me, but he said it was a poor connection) it is for Turbocharger boost control position sensor ''A''. I stopped a few times, turning off the car each time. Last stop the light went off. Which leads me to believe it is only a sensor this time. The car drives fine still, not like last time when it completely scared me with shifting trying to get up to highway speeds.
I am just wondering where this sensor position is. I have looked through a couple of the forums but I can't pinpoint through those where I should start looking. I don't think anything with the Turbo is covered by Powertrain sooooooo I must start here.
Please & thanks.
