LB7: Barometric pressure

[JustinD]

On my most recent log I see that the barometric pressure is 8.3, but all the other LB7 logs I have looked at it is at 14.5-14.6??? Is this an issue and what might cause it?


Thanks guys!

If I had to guess I would say the baro sensor is on it's way out

On the drivers side looks like the MAP sensor but a diff part number?? What causes them to go bad? I put a new one last fall. What would a bad baro cause it to do??

Bringing up an Old Thread.. I keep getting the code for the Barometric Pressure sensor.. I dont remember the number right now Boost Level on the CTS monitor reads ok..Nothing out of spite..

Depends on which baro code it is. P2227, P2228, or P2229? Could be either a baro or boost sensor issue, or wiring issues with one of them.

Yup.. Looked it up earlier,it was the P2227 code..
