OR
- The ECM detects that the boost pressure sensor signal is less than 44 kPa (6 psi) or greater than 115 kPa (16.7 psi) when the ignition is On and the engine is NOT rotating.
OR
- The ECM detects that the difference between MAP and BARO is less than or equal to 10 kPa and the difference between turbocharger boost pressure and MAP is greater than 10 kPa and the difference between turbocharger boost pressure and BARO is greater than 10 kPa when the ignition is On and the engine is NOT rotating.
