Map Sensor

Anyone got any ideas why the map sensor would not be receiving a signal or has low signal?

I have replaced the map sensor and also the map cables, Cleaned the egr valve and it still wont got away. Diag says po235.

Have you got MES? If so, plug it in and see what the engine ecu is seeing from the MAP.
It should read about 1000mbar with engine off.

It could well be something else causing it. Dont just assume that code is the MAP.
Could be not enough boost with engine running.

Also check that it is receing 5V from the ecu.
