ive got fault code 2221 no manifold presser signal to ecu but pressures there and the boad coputer shows bost on the gage could this be an ecu problum and how do i fix it
thanks

So... what do we know?

The pressure xducer is working and the value is being displayed on the factory boost gauge.

On the schematic there must be a path that takes that information directly to the display driver. Another path will take it to the processor in the ECU... at least it should. You could try messing around with it and....

Nah... why bother. Get a spare from the wrecker and replace it.

Capacitors dry out. They are the little metal cans that you see in there. The electrolytic solution drys up especially in high heat situations... say like in a car parked in the summer sun ;-)

I've bee thinking of replacing all the caps in a spare just in case.

Would anyone be interested in a parts list?

Ive been meaning to do an entire trace of my spare some day.. It would probably take a while though :-/
