Having a serious problem with my k swap. So I've checked for continuity from the map sensor plug to the ecu plug for the signal wire, no short in the wire. Tested ground and 5v reference on the map sensor plug it's getting 5v. Tried to test the map sensor by sucking the inlet to cause a vacuum reads voltage change on the multimeter but k manager shows no change. Why is this even possible I've even tried another MAP sensor.
