Hot-Idle Compensation System

Verify idle compensator valve is closed when bimetallic sensor temperature is less than 145-160°F (63-71°C). See Figure . With valve closed, suck air through hose connected to valve. If excessive air leakage is found, replace idle compensator as an assembly. When bimetallic sensor temperature is greater than approximately 160°F (71°C), verify valve is open. If valve is not open, replace idle compensator as an assembly.
