Barometric Pressure Sensor: Testing and Inspection

The Barometric Pressure (BARO) Sensor is located integral to the Programmed Fuel Injection Electronic Control Module (PGM-FI ECM) and cannot be accessed to be tested separately. To test, substitute a known good PGM-FI ECM. If symptom or Diagnostic Trouble Code indication goes away, replace original PGM-FI ECM.
