    I have an 09 isx with dpf and egr. I get the check engine light for intake manifold temperature electrical fault and the fan stays on. After a while it goes aways and tries to regen but fails after it fails it seems good. But I don't have any boost I was getting 33 psi now I get 18 max. The intake code goes away and comes back could it be sensor.

    Sounds like a turbo to me. Do you have a pyrometer?

    Is it reading high? If a turbo doesn't push enough air or if that pressure is compromised (bad CAC) you can get high exhaust temps.

    No it reads normal around the 600 when loaded on hard pulls close to 900. I seen those videos is the intake manifold the imap sensor he talks about?
