FAQ
What does PSIa mean on this MAP sensor?
PSIa stands for pounds per square inch absolute; the sensor references absolute zero rather than atmospheric pressure, letting it measure both vacuum and boost.
How is the 30-2131-75 wired?
This brass sensor kit comes with a flying lead for direct wiring rather than a plug-in connector body.
What pressure range does the 30-2131-75 cover?
This kit measures up to 5 Bar, equal to 75 PSIA, with an accuracy of within 3%.
