So yeah, I pulled the map sensor off to relocate it and found a tremendous amount of water.

The car never stopped running and has been running normally, nothing unusual.

I got the water out, and spayed electronic component cleaner in, got that out and hooked the sensor up to a vacuum source (a small vac test pump) and will keep vacuum on it overnight to get out any remaining moisture.

Should the senor be replaced as a precaution,
again let me stress that the car is behaving normally, not a sign that anything was wrong.

 

You need the check valve that prevents water from filling the tube. And i would suggest a new sencer since its responsible for keeping the engine from going lean.

 

It should be mounted as high as possible as to not have water or anything flow down into it. Its hard for water and stuff to flow uphill. If condensation has formed then it would flow down the vac line into the manifold.

 

does anyone have any experience hear, the water is actually water/meth mix, has anyone had a sensor get wet and still used it?

I'm thinking its probably fine but may just get a new one.

I tested the sensor with a vacuum pump watching the haltech screen and its right on?

There was a little down hill spot in the line that apparently let it run in. its going to be remounted so that the nipple is physically facing down with the water filter and the line below it all the way.

 

Dunno what happens when you DROWN the sensor, but it does act as a dead-end.
I think the Haltech manual explicitly states to mount the sensor with the nipple facing down to prevent damage from something like this?

Correct, and also to mount it higher than the highest point in the plenum to prevent fluids from riding up like the previous post have stated.

If the sensor is still working fine and displaying correct readings it might be ok to keep it, but i would have anotherone on hand just in case.
