Test Procedure

NOTE: BARO sensor is located in Volume Air Flow (VAF) sensor.
  1. Turn ignition on. Using scan tool, check if DTC P0107 is also set. If DTC P0107 is also set, troubleshoot DTC P0107: BAROMETRIC PRESSURE SENSOR CIRCUIT LOW INPUT  first, then recheck for DTC P0106. If DTC P0106 is the only code set, go to next step.
  2. Check VAF sensor connector for loose, damaged, or corroded terminals. If problem exists, repair or replace connector. Go to step  9. If problem does not exist, go to next step.
  3. Disconnect VAF sensor connector. See Figure. Check continuity between ground and VAF sensor connector terminal No. 5 (Black wire). If continuity exists, go to step  6. If continuity does not exist, go to next step.
  4. Check PCM connector D-108 connector for loose, damaged, or corroded terminals. If problem exists, repair or replace connector. Go to step  9. If problem does not exist, go to next step.
  5. Check for continuity between PCM connector D-108 terminal No. 57 and VAF sensor connector terminal No. 5 (Black wire). If there is continuity, replace PCM and go to step  9. If there is no continuity, repair open circuit in Black wire between PCM connector D-108 terminal No. 57 and VAF sensor connector terminal No. 5. Then go to step  9.
  6. Turn ignition off. Check PCM connector D-108 for loose, damaged, or corroded terminals. If problem exists, repair or replace connector. Go to step  9. If problem does not exist, go to next step.
  7. Check VAF sensor and PCM connector D-108 connectors for loose, damaged, or corroded terminals. If problem exists, repair or replace connector(s). Go to step  9. If problem does not exist, go to next step.
  8. Replace BARO sensor. Using scan tool, clear DTCs. Test drive vehicle following OBD-II drive cycle Other Monitor pattern. See OTHER MONITOR  under OBD-II DRIVE CYCLES under VERIFYING REPAIRS. Check for DTCs. If DTC P0106 is output, replace PCM. Go to next step. If DTC P0106 is not output, inspection is complete.
  9. Using scan tool, clear DTCs. Test drive vehicle following OBD-II drive cycle Other Monitor pattern. See OTHER MONITOR  under OBD-II DRIVE CYCLES under VERIFYING REPAIRS. Check for DTCs. If DTC P0106 is output, go to step  1 and retry diagnostic procedure. If DTC P0106 is not output, inspection is complete.
