MAP readings are high

[cbennet12]

The attachments demonstrate the data I see on the C37_P26 pin versus the value displayed on the screen (about 6 inhg too high).

Double checked the connections including ground and they look fine. The manifold input is currently unconnected so blockage is not the issue.

Other things to check?

You can get this kind of value if you mix up the connections, so please double check which one goes to each pin.

Also verify you have 5V between ground and power at the sensor.

If all of those are good, then it's likely a bad sensor.
