Pinpoint Test BARO - Barometric Pressure Sensor

NOTE: Enter this procedure only when Code 14 is displayed during QUICK TESTS procedure or when directed here from another PINPOINT TEST. To prevent unnecessary replacement of components, note following non-EEC items may be at fault: unusually high or low atmospheric pressure, blocked vacuum lines, or basic mechanical engine components.
