P1105 barometric pressure not plausible with boost

[ian mc]

Any idea's what this could be people. MAP sensor?
only seems to come on a idle or low revs, i.e reversing of the drive.
sometimes it clears itself after few seconds and sometimes it stays on

Could be an air leak best to check all hoses for splits

[ian mc]

could it be a vacumn leak? it seems to happen when the turbo isn't even spooled up

[paul wingnut]

the boost press sensor on top of throttle valve housing will be the culprit if its a y20dth enngine very common

[ian mc]

no mines a y22dtr

no mines a y22dtr

Same thing.

Had this with a cdti corsa a few weeks ago, the vx dealer dealer took £56 from him & told him it would be a further £70+ for in-depth diagnostics, but in there opinion it was the turbo, After a call to me i pleaded with him to wait till i was back from hols in 2 days, op-com'd it changed the boost sensor jobs a good un!, strange realy why they get called & slagged off so much! cant understand it! to**ers.

going to try cleaning the boost sensor now, i wouldn't of believe it was the turbo, only put a new one on a year ago!

I will let you know
