| Component | Barometric Absolute Pressure Sensor |
| Description | The
BP sensor measures barometric pressure using a frequency. This gives
the EEC information on engine load. The BP is used as a barometric
pressure sensor for altitude compensation, updating the EEC during Key
On Engine Off and every wide-open throttle.
The EEC uses the BP information for: Spark advance EGR flow Air/Fuel ratio |
| Location | Mounted behind Integrated Relay Controller; in front of passenger strut tower. |
