Vauxhall Corsa y13dt Barometric problem!

Post by bullstar » Sat Feb 09, 2013 1:36 pm

Hi all
Just had a vauxhall Corsa van 1.3 cdti in and customer says van is loosing power and going into limp mode somtimes and seems like the car is not boosting.

I pulled the codes out using Autoboss v30, The DTC said: P0108 - 7 undefined trouble code.

Live data said Barometric pressure 99 kpa and volts said 3.7 this data stayed the same on idle, throttle,and with just key on position!

Boost pressure 94 kpa and 1.76 v on idle, Boost pressure reading were up under load.

The customer has fitted new egr valve, map sensor and maf meter.

I hooked the scope up to the map sensor and this is what the reading was:
