P0108 engine code ( high signal MAP / BAR0 ).

Any ideas on cause, solution?

Car is mapped with Perrin 4 bar MAP sensor, SC46 billet turbo, AEM CAIK with larger inlet pipe etc.


Is it a sensor fault, leak, some other problem?

Thanks

 

Usually very high boost pressure in the manifold.
I had this problem once & the pipe had come off the compressor cover on the turbo to the boost solonoid
