Sorry to pick this thread up so late but I've had all of the above, changed the sensor for a Renault compatible one but the fault code is still coming on after a day or two. Can anyone help ? The maintenance manual suggests changing the ECU ....surely this can't be....any ideas ?
I should mention that the maintenance CD I have suggests checking the wiring back to the ECU...which again I have done and all seem hooked up ok.

Surely this sensor has another function other then waiting to go wrong ? If it is detecting a fault , what fault could cause the TC boost pressure to fail ?

A new ECU is about half the cost of the car, (2008 Aventura).

I find myself in somewhat of a pickle.
