Toyota Sienna Service Manual: Inspection
1. INSPECT CHARCOAL CANISTER ASSEMBLY
(a) Visually check the charcoal canister for cracks or damage.
If cracks or damage are found, replace the charcoal canister assembly.
(b) Check charcoal canister operation.
(1) With the purge port closed, blow 1.67 kPa (17.0 gf/cm2, 0.24 psi) of air into the vent port, and check that air flows from the air inlet port.
If the result is not as specified, replace the charcoal canister assembly.
(2) With the vent port closed, blow 1.10 kPa (11.2 gf/cm2, 0.16 psi) of air to the air inlet port, and check that air flows from the purge port.
If the result is not as specified, replace the charcoal canister assembly.
(c) Check for air leakage.
(1) Remove the air hose between ports A and B.
(2) Connect SST (pressure gauge) to the vent port of the charcoal canister.
SST 09992-00242 (3) While holding port B, with the purge port and the air inlet port closed and port A open, apply 19.6 kPa (0.2 kgf/cm2, 2.81 psi) of pressurized air into the vent port, then confirm that pressure is retained for 1 minute.
If the result is not as specified, replace the charcoal canister assembly.
(d) Check the leak detection pump.
(1) Remove the detection pump from the charcoal canister.
(2) Check that air flows from port A to B and then C.
If the result is not as specified, replace the charcoal canister assembly.
(3) Connect the positive (+) lead to terminal 7 and the negative (-) lead to terminal 6.
(4) Check that the valve is closed.
If the result is not as specified, replace the charcoal canister assembly.
(5) Install the detection pump.

Mass or Volume Air Flow Circuit High Input
DESCRIPTION
The Mass Air Flow (MAF) meter is a sensor that measures the amount of air
flowing through the throttle
valve. The ECM uses this information to determine the fuel injection time and to
provide appropriate airfuel
ratio. Inside the MAF meter, there is a heated platinum wire which is ...

Rear Air Outlet Damper Control Servo Motor Circuit
DESCRIPTION
This circuit turns the servo motor and changes each damper position by
receiving the signals from the A/
C amplifier.
The rear air outlet damper servo motor switches the air outlet mode by rotating
(normal, reverse) with
electrical power from the A/C amplifier.
