MAP Sensor

Display shows manifold pressure in Kilo Pascals (kpa) from 10 to 104 and voltage from 0 to 5.0. At key ON, engine not running, the MAP value will reflect barometric pressure. To check for an accurate MAP reading multiply your local barometric pressure by 3.386 to obtain a map value that should be within 2 kPa of displayed value at key ON, engine not running.
