Test BP - Barometric Pressure Sensor

1991 Ford Probe GL, StandardSECTION Test BP - Barometric Pressure Sensor
NOTE: Enter this test only when Code 14 is displayed during SELF-TEST procedures, or when directed here from another CIRCUIT TEST. To prevent unnecessary replacement of components, check for fault in the following non-EEC items: atmospheric barometer reading (unusually high or low), vacuum lines (blocked), and basic mechanical engine components.

Visually check all wiring, connectors and components for evidence of damage, shorting or looseness. If a fault is found, repair as necessary. If no fault is found, erase codes from memory. Perform KOEO and KOER self-tests. See SELF-TEST. If Code 14 continues to appear, replace ECA.

NOTE: The barometric pressure sensor is built into the ECA and cannot be replace separately. If Code 14 appears repeatedly after clearing codes, replace ECA.
