Is This A 2-bar Or 3-bar Map Sensor?

[soldave]

Hey there. Am a guy with an early Evo checking in and looking for some help for you knowledgeable MR2 folk. Have found I need a 3-bar MAP sensor for a mod I'm doing on my car and it just so happens one of my friend has got one lying in his garage. It came out of an MR2 apparently and he thinks it's 3-bar but I want to make sure. The serial number (and then number underneath that) on the sensor is:

89420-17040

100798-2002

I know the 17030 is a 2-bar and the 17050 is a 3-bar but what about this one? Many thanks for any advice you guys out there can offer me about this. :)

EDIT: Well, have found one link which would suggest that MAP sensor is out of a 2.2L 5SFE engine in an MR2, which is a USDM one. Maybe that might help someone.
