    I am cleaning my intake manifold and I accidentally forgot to remove the MAP sensor which is down by the throttle body on the intake manifold and I was blasting it out with Brake cleaner first and small pipe cleaner nylon brushes and I finally soaked it in purple power and hot water. I heard you can clean them with mass air flow sensor spray cleaner. Did I ruin the sensor by submerging it? If so what is a decent non Denso brand MAP sensor brand (Delphi?) I can buy to replace the sensor. I seen that the brand name sensors are really expensive. I guess I could also clean it gently with Mass Air flow sensor cleaner and put it together and see if it throws a code too.

    Let us know how that turns out.
    My guess is that it will be ok.

    All it has to do is say what the air pressure is. You could plug it in and watch the reading on a scan tool.

    If it's close to what your local weather station says when the engine is off, there you go.

    My car has been acting up were it will sporadicly and randomly start to idle roughly. I decided to clean my EGR cooler and EGR valve and now I am cleaning the intake manifold. I read that the egr valve and cooler and intake manifold can cause the car to run roughly especially if they are full of packed in exhaust carbon deposits

    I have a Creeder Launch scan tool. I don't have Techstream. I doubt if my reader can give anything but normal or abnormal function codes. Hopefully it works after being washed and I get no codes
