There is no part number on the actual device, only the plastic bag it came in.At ambient pressure it reads 4.65 volts, on applying vacuum voltage goes down.Appears to only be a 1 Bar device, not 3 Bar as listed.Should have listened to the other reviews, but I was hopeful.Sending back, will try again with a different vendor.

This product doesn't function at all, tested and signal reads a constant voltage. What a waste of my time!

Supplied plug doesn't even fit in the sensor, scales as a 1 bar map sensor not a 3 bar

This sensor scales as a 1 bar MAP sensor.
