Chevrolet

1 Interpretation
P1451
Barometric pressure (BARO) sensor performance range Chevrolet · engine Datenzuverlässigkeit 80%

The control module detected a fault associated with the Barometric pressure (BARO) sensor performance range circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.

Mögliche Ursachen

  • Wiring
  • poor connections
  • BARO sensor
  • ECM

Chrysler
