Barometric Pressure Sensor Electric Fault
1992-1998 BMW 325i E36 2.5L I6 M50 🇷🇺
Description
The DME detected an electrical malfunction in the barometric pressure sensor circuit. This sensor provides altitude compensation data for fuel and ignition calculations.
Symptoms
- Check Engine Light
- Poor high-altitude performance
- Incorrect fuel mixture
- Reduced power
Common Causes
- Faulty barometric pressure sensor
- Wiring damage to sensor
- Corroded sensor connector
- DME internal reference voltage fault
Diagnostic Steps
- Test sensor supply voltage
- Check sensor output signal range
- Inspect wiring and connector
- Compare barometric reading with known altitude
Repair Notes
Replace the barometric pressure sensor or repair the wiring fault.
