- Using ohmmeter, check for continuity between terminals and VSV body. If continuity exists, unit is shorted. Replace valve if defective.
- Using ohmmeter, measure resistance between both terminals of valve assembly. Resistance should be 38-44 ohms at 68°F (20°C). Replace valve if resistance is not within specification.
