    Map sensor locations

    Hi again, sorry if this makes some of you upset I have tryed to search it. I'm new to the msx 150 model. I have all the manuals printed out. I still cannot locate the map sensors. Maybe I am looking for the wrong things. I know where the air, cam, knock, and 02 sensors are. Any info would be great thanks.

    The map sensor is located on the intake plenum, at the front of the engine and slightly lower than the throttle body. It is #4 on the picture below.

    Another clue of why the msx was running a bit funny!



    Would you say blow by or oil over fill? This is the lower map sensor on the msx 150.

    Oil overfill with water contamination evaporating in the intake circuit. Please refer to this older discussion and address the cyclone issue I presented..... it will solve your issues. MSX110/150 owners should concsider doing the simple cyclone modification I presented.... trust me on this one.

    Can the sensor be cleaned or does it need to be replaced?

    I think I have the same issue.

    Thanks

    Normally, the answer is no. This sensor serves a double function.... it reads absolute pressure and it also read air intake temperature. The coating on the sensor signal heads is fragile and is easily destroyed by oil and water.

    Unfortunately Desperado is right, They may check out OK under test conditions but still will not work. Remove the breather that goes into the intake replace both MAP sensors and never look back.

    sensors

    So buying 2 of these should do it for having a set of backups?

    Looks like a good deal! If you fix the oil ingestion problem you should never ever need to replace them, but for that price I would keep a couple in my spares.
