    Basic RAM MAP Sensor Question

    Is this MAP sensor reading normal?

    51 Kpa when off and 21 Kpa at idle.

    Fuel Trims are also off. Maybe because of this?

    What can I do about this?

    Try a vacuum gauge on the engine and see if it matches at idle?

    Should be around 14.7psi, give or take, key on engine off.

    Looks like 14.7psi is around 100kpa.

    yeah that's not right. Can you post a tune and whats mods? As spoolboy said, MAP should read around 100kpa KOEO, and the BARO should read that all the time.

    Either the MAP has failed, scaled improperly in the tune or the wrong MAP sensor has been installed.
