Circuit Description
Barometric pressure sensor reading is displayed from PCM when ignition is on, engine is off, and at wide open throttle. Barometric pressure sensor represents barometric pressure and is used to compensate for altitude changes. DTC P1450 will set when:
- Barometric pressure is less than 4.79 psi (0.33 kg/cm2 ).
- Barometric pressure is 19.6 psi (0.14 kg/cm2 ) or more.
