  1. Engine idling, move the related harnesses/connectors at the BARO sensor and at the ECM while observing the scan tool BARO sensor parameter. The scan tool BARO parameter should be steady.
    • If the parameter does not perform as specified, repair the harness/connectors as necessary.
  2. If all circuits test normal, test or replace the BARO sensor.
