P00F7 Barometric Pressure - Turbocharger/Supercharger Inlet Pressure Correlation Bank 2

This is the bank 2 counterpart of the comparison between barometric pressure and the pressure ahead of the turbocharger or supercharger. At low air flow the inlet pressure sensor reads close to ambient pressure, minus the small loss across the air filter, so it must match the barometric reading. The code is set when the difference is too large; a clogged air filter or a leaking intake hose on bank 2 can cause it as well as a drifting sensor. None of the published manufacturer documents searched uses this code; the explanation follows regulations and comparable manufacturer monitors.
Likely causes
Inlet pressure sensor of bank 2 drifting or dirty
Air filter or intake of bank 2 clogged
Intake hose between air flow meter and turbocharger leaking or slipped off
Barometric sensor faulty
Symptoms
- Check engine light on
- Reduced power or boost limitation possible
- Whistling from an intake leak
