Another problem or two

Hey, look at this andy - sounds exactly like your problem:

Oh, and it does look like PIM is the MAP sensor.

lol, I just stumbled accross that myself

Hopefully problem solved then! there is another thing I thought though, theres a bloke in there mentions he had that problem when he unplugged his apexi boost controller, something about it being on a circuit loop. I haven\'t got the boost controller but I have got electrical boost gauge which I recently unplugged cos it wasnt working (its one of those ones which the control box), im am 90% sure I drove the car after that was unplugged so hopefully can rule that out. MAP sensor seems the way to go

Thanks for the help

No, i really don\'t think the electronic boost gauge will have anything to do with it. All that does is take a reading from the same sensor - in fact that may be why you thought the boost gauge had failed - because the map sensor was on it\'s way out.

ah, good point, it did fail gradually, started to waver then didnt show a reading at all, could have been the map sensor dying off, suprised it didnt affect driving characteristics though...still, I think its what todays problem is Might get a new one even if I can get old one working, providing Mazda dont require too many limbs for it

Morning chaps,

I swapped the map sensor over yesterday with a new one and unfortunately the  pim voltage is still flagged in black, didnt get chance to try and turn it over as I fried the battery charger before it got fully charged up, but as pim is still showing 4.99v and in black no point really.

Any suggestions for next place to check. The problem has only occured from being sat for a few months, im guessing its something thats corroded or got damp as it was fine beforehand.
