P1108 ACURA Description
The barometric pressure (BARO) sensor is built into the Engine Control Module (ECM) and monitors atmospheric pressure. The ECM estimates appropriate intake airflow from the manifold absolute pressure (MAP) sensor output voltage and BARO sensor output voltage. If the BARO sensor output voltage is a specified value or more, the ECM detects a malfunction and a DTC is stored.
