Title: Vacuum pump sensor
Post by: Barkered on October 08, 2022, 09:11:51 am

Hello,

My Cx5 is showing the dreaded P258B, vacuum pump error.

I've tried clearing various sensors out but the error returns.

I don't experience any stiffness with the brakes, so I'm not convinced it's the actual pump.

Is there a dedicated sensor I can maybe replace or clean before I look to replace the pump?

Cheers.
