Intake air control system (2AZ−FE (PZEV)) (From July, 2003)

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.
