How can I test a MAP sensor?

96 civic EX

There is an easy way to test a MAP sensor with an ohm meter, if so how?

Also what is the proper working ohm range?

You MUST provide all pertinent information about your car and engine. Failure to do so may result in thread closure.

Measure the output voltage to body ground from the MAP sensor with:

1) The key in ON(II)/engine off (should be ~3V)

2) The engine idling (should be <1V)

You unplug the connector right, I have not looked at it yet, is there metal terminals inside of it to probe? if so which one?

Nothing is unplugged. Back probe the Red/Grn wire in the MAP sensor connector.

Oh, thanks, so basically positive to that wire and then ground on the block?
