Electronic Air Bleed Air Control Valve (EBCV)

1. Check EBCV for short. Disconnect EBCV connector. Using an ohmmeter, check for continuity between positive EBCV terminal and body ground. See Fig 1 or Fig 2. Continuity should not exist. If continuity does exist, replace EBCV.
2. Check EBCV for open. Using an ohmmeter, measure resistance between EBCV connector terminals. See Fig 1 or Fig 2. Resistance should be 11-13 ohms at 68°F (20°C). If resistance is not within specification, replace EBCV.
