October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Atmospheric Pressure Sensor

Pressure sensor is installed on airflow sensor. It senses atmospheric pressure and converts it to voltage which is sent to ECU. The ECU uses this signal to compute altitude. It then corrects air/fuel ratio and ignition timing for better driveability at high altitude.
