P00F7Barometric Pressure - Turbocharger/Supercharger Inlet Pressure Correlation Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Check engine light on
- Reduced power or boost limitation possible
- Whistling from an intake leak
- Likely causes
- LikelyInlet pressure sensor of bank 2 drifting or dirty
- PossibleAir filter or intake of bank 2 clogged
- PossibleIntake hose between air flow meter and turbocharger leaking or slipped off
- RareBarometric sensor faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
