Got this one in with EML on. fault code P0238 turbo pressure sensor a high input.I have checked all turbo hoses and vacuum hoses. Scoped at pressure sensor, scoped duty cycle and power at boost pressure solenoid, All seem fine. When you rev at idle you can see waste gate moving, On live data under load boost pressure hits 2498 MBAR then EML will come on. Is that to high? Thought 2100MBAR to be normal under load?
What would cause over boost?
Thanks in advance
Shane
