Atmospheric Pressure Sensor Test: Notes
- Remove left side kick panel. Remove rubber cap from atmospheric pressure sensor. Attach hand-held vacuum pump to sensor port. Turn ignition on. Check voltage between each terminal and ground while applying and releasing 30 in. Hg to sensor. See Figure
.
- If voltage at terminals "A", "B" or "C" are not within specification, check wiring harness to sensor. If voltage at terminals "A", "B" or "C" is within specification, but terminal "D" is not within specification, replace atmospheric pressure sensor.
