CR-V LX 4WD L4-1972cc 2.0L DOHC MFI (2000)
Idle Up Control Valve: Testing and Inspection
NOTE: The fast idle thermo valve is factory adjusted; it should not be disassembled.
1. Remove the intake air duct from the throttle body.
2. Start the engine.
3. Put your finger over the lower port in throttle body, and make sure that there is air flow with the engine cold (engine coolant temperature below 86
°F, 30 °C).
If there is no air flow, replace the fast idle thermo valve and retest.
4. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on, then let it idle.
5. Check that the valve is completely closed. If the valve is leaking, the idle speed will drop when you cover the lower port. Check the engine coolant
level and for air in the engine cooling system . If the cooling system is OK, replace the fast idle thermo valve and recheck.
