Barometric Pressure Circuit Range/Performance
The barometric pressure sensor delivers an electrically valid signal that does not match the operating point — for example pressure jumps that do not match altitude changes, or values stuck near full scale.
Affected components
- Barometric pressure sensor
- Sensor wiring
Common causes
- High likelihood: Sensor drift
- Medium likelihood: Connector corroded
- Low likelihood: Sensor element aged beyond calibration window
Diagnostic notes
