Hi There,

Engine management light came on in the snow. Took my 1.9 JTD Stilo MW to a garage. These are the codes he gave me P0110 IAT SENSOR signal too large, P0235 boost pressure sensor signal improbable, P0236 value 4 boost pressure control short to B +, P0101 air mass sensor signal too small.
Garage says P0236 is possible problem causing all other codes to fault up. Garage cleared P0110,P0235 & P0101, but said they would come back. What part do I need to cure P0236? (Is this an overbooster problem or map sensor?).

Thanks

What problem do you have with the car. Codes on their own are seldom of any use.

HI There

Thanks for getting back to me. The problem, it has no power reving in gear upto approximately 3000 rpm and 15 to 20 mph up a hill. Down hill upto 60 mph but it wont maintain that speed. Driving like a snail basically.

Thanks for the reply.

If it happened in the snow and your VGT (overboost) valve is still down underneath the headlamps then that's highly likely to be your problem.
