Air Intake Solenoid Valve Resistance
Standard: 22
26 Ω at 20°C (68°F)
If the resistance reading is out of the specified value, replace it with a new one.



If the air intake solenoid valve does not operate as described, replace it with a new one.
NOTE
To check air flow through the air intake solenoid valve, just blow through the air intake solenoid valve hose (intake side) [C].
