Need a little help I have a 94 XR7 with a 3.8, ok here's the problem i'am getting a code 157 which i understand is a mas sensor. I have pulled the mas out and cleaned it no broken wires all is good there. So why i'am i still getting a code? Can you check it to see if it works? If so how do you do that? Any pictures oftesting a mas? Or diagram on it. Any help would be great.

I don't know of a test for them. I would say to order a new one and swope it. It's solid state so there is really nothing to test. You could call ford and talk to a tech for any procedure they may have?

Just checking, but after you cleaned the sensor did you reset the computer?

Unplug the battery for ten minutes or remove the ECM fuse and crank the engine a few times then try it. Any codes you had should be cleared.

Just a suggestion, but I would post in the IL chapter and see if someone close has a MAS you can borrow and test with.
