Hello. My name is ***** ***** I will be helping you today.

Its a boost pressure solenoid

Customer: replied 1 year ago.
Ok what about this one
Customer: replied 1 year ago.
Is this a boost pressure solenoid too?
So my car have 2 of them?
Expert:  Wayne Crawford replied 1 year ago.

Same thing. Ones technically a MAP sensor but they are the same part.

Customer: replied 1 year ago.
On this one there's a vacuum hose and I disconnect the other one and I blow air into it easily and I connect it a vacuum pump and it doesn't create a vacuum so that this means that there's an air leak?
Expert:  Wayne Crawford replied 1 year ago.

That means the switch is stuck open

Expert:  Wayne Crawford replied 1 year ago.

What is the issue you are having?

Customer: replied 1 year ago.
I have an over boost code
Customer: replied 1 year ago.
What switch?
Expert:  Wayne Crawford replied 1 year ago.

Swap those two sensors and clear the codes and see if the same code comes back or a map sensor code.

When I said that I was blowing air easily and I put a vacuum tester I was talking about the hose not the selenoid
Expert:  Wayne Crawford replied 1 year ago.

Is it running bad too?

Customer: replied 1 year ago.
Expert:  Wayne Crawford replied 1 year ago.

Does your scan tool show you boost pressure?

Customer: replied 1 year ago.
Nop
Expert:  Wayne Crawford replied 1 year ago.

Try bypassing the boost pressure sensor with a barbed hose coupler and see how it runs.,

Customer: replied 1 year ago.
Boost presure sensor is new in installed today
Customer: replied 1 year ago.
I'm concern about this one
Expert:  Wayne Crawford replied 1 year ago.

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?

Expert:  Wayne Crawford replied 1 year ago.

Why are you concerned about the map sensor?

Customer: replied 1 year ago.
I think is working fine. But my cuestión to you is , if there's a hole in the house coming out of the map could it cost the overboost? And where does that hose gose to?
Expert:  Wayne Crawford replied 1 year ago.

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?

Customer: replied 1 year ago.
Ok thank u I'll chek it out
Expert:  Wayne Crawford replied 1 year ago.

No problem.
