    To those better informed (than me!) in the newsgroup.

    The diagnostic test ran by the local Peugeot dealer tells me that I
    have a faulty MAP sensor.

    I've found out what it does, but on a 405 (2.0i 1993), where is it and
    what does it look like?

    If you look on your inlet manifold, there should be a thin plastic
    tube, connected to the manifold with a rubber pipe. Follow this pipe
    to where it ends and there will be the MAP sensor. If you're lucky,
    it'll be a smallish square unit above the rad. But if you're really
    unlucky, it'll be incorporated in the ECU!!! New ECU needed. Around
    £700 from Pug. Try and find one at a scrapper.
