    Hey all,

    I was trying to clean the MAP sensor and snapped a seizes bolt trying to get it off. Any ideas on where I can get a new one? Or ideas on how to extract the seized bolt?
    Thanks

    I believe the MAF sensor is, but it looks like the MAP sensor is bolted into a metal fitting inside of the plastic

    Did you by chance ever clean the intake manifold with caustic solution?

    It’s a 10mm bolt, I’m sure the dealership has the part. You can also call the dealership for the part numbers as well since they have the diagram for it.
