Hello. My name is ***** ***** I will be helping you today.
Its a boost pressure solenoid
Same thing. Ones technically a MAP sensor but they are the same part.
That means the switch is stuck open
What is the issue you are having?
Swap those two sensors and clear the codes and see if the same code comes back or a map sensor code.
Whats your code?
Is it running bad too?
Does your scan tool show you boost pressure?
Try bypassing the boost pressure sensor with a barbed hose coupler and see how it runs.,
If its not the sensor its either gonna be a leak or bad turbo. Without any data from the PCM I cant tell you which. Do you have access to a smoke machine?
Why are you concerned about the map sensor?
It has nothing to do with your issue.
If your issue isnt the boost pressure sensor its either a leak in the plumbing or a bad turbo. Remove the hose from the turbo and feel the turbine. Does it spin freely. Does it have any play in it?
