Check light came on my 2004 2500HD LLY. Had the code pulled today and it shows Turbo Boost Sensor. About the same time it started coughing back through the Turbo.
Anyone know where to find info on where to find this part on the motor and change it out? Stopped by the local parts place and they gave me a quote of $105. for the Sensor.
Also how hard is it to pull the sensor that adjust the turbo? And any ideal what size bolt that is below the deal? It looks like I have to remove the oil line and that bolt under that sensor on the drivers side of the Turbo?

Need to know what size socket it takes to remove the Turbocharger Vane Position Control Solenoid Valve? Think that's it? The one on the passenger side of the Turbo. Also if anything else needs to come out before it does? I know the oil line has to be out of the way.

Thinking it needs cleaning, Would the one with white wire need cleaning also?

Be careful with that solenoid. Several orings and screens there. Operates off a combination of electrical actuation and oil pressure.

Testing the vane position sensor is simple if you have a tuner that will display vane position.

Good luck with your truck.
