- The ECM detects that various combinations of Turbocharger Intake Flow Rationality Diagnostic Failure models, derived from engine speed, the BARO sensor, the MAF sensor, the MAP sensor, the throttle position sensor and the turbocharger boost pressure sensor have failed when the engine is running.
OR
- The ECM detects that the boost pressure sensor signal is less than 50 kPa (7.3 psi) or greater than 115 kPa (16.7 psi) when the ignition is ON and the engine is NOT rotating.
OR
- The absolute value of the difference between MAP and boost pressure is greater than 10 kPa and between MAP and BARO 1 is 10 kPa or less and between MAP and BARO 2 is 10 kPa or less and between boost pressure and BARO 1 is greater than 10 kPa and the between boost pressure and BARO 2 is greater than 10 kPa and between BARO 1 and BARO 2 is 10 kPa or less.
