can anyone shed any light on this one?
I have a 2007 corsa D,its a 1.2 petrol and the engine light is on.
ive plugged the car into a scanner and got 1 fault code
PO068-manifold absolute pressure sensor circuit range/performance.
Ive wiped the code but it comes back as soon as you start the engine!
ive fitted a new map sensor and grommet but this has made no difference at all.
The voltage seems fixed at 4.82 volts and the pressure is fixed at 101 kPa.
this does not alter with the engine stopped or running or the map sensor plugged in or unplugged!
Any ideas???
