Barometric Pressure Sensor Electric Fault
1992-1996 BMW 318is E36 1.8L I4
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.
