INSPECTION
1. INSPECT INTAKE MANIFOLD RUNNER VALVE ASSY
a. Check the intake manifold runner valve.
1. Check that intake manifold runner valve shaft is not rickety.
NOTICE: Do not adjust the screw.
b. Check the intake manifold runner valve operation.
1. Apply battery positive and negative voltages across the terminals.
Standard
:
2. Check that the intake manifold runner valve opens and closes smoothly.
If the result is not as specified, replace the intake manifold runner valve assy.
NOTICE: Do not apply the battery voltage to the intake manifold runner valve for more than 1 minute.
c. Check the resistance.
1. Using an ohmmeter, measure the resistance between the terminals.
Standard
:
If the result is not as specified, replace the intake manifold runner valve assy.
