Barometric Pressure Circuit High
The barometric pressure sensor reports a voltage above the upper limit. The signal cannot represent any realistic atmospheric pressure, indicating an open circuit or short to supply voltage.
Affected components
- Barometric pressure sensor
- Bps wiring
Common causes
- High likelihood: Signal shorted to supply voltage
- Medium likelihood: Open in signal or ground wire
- Low likelihood: Connector pins corroded - high contact resistance
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
- A drive cycle may be required after repair
