CHECKING THE AIR INDUCTION SYSTEM
SOLENOID
1. Check:
• Air induction system solenoid resistance
Out of specification → Replace.
Solenoid resistance
18–22 Ω at 20°C (68°F)

a. Disconnect the air induction system sole-
noid coupler from the air induction system
solenoid.
b. Connect the pocket tester (Ω × 1) to the air
induction system solenoid terminal as
shown.
