PROCEDURE
PRECAUTION
Note
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notice before proceeding with work.
DISCHARGE FUEL SYSTEM PRESSURE
DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
Note
When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
REMOVE WINDSHIELD WIPER MOTOR AND LINK ASSEMBLY
REMOVE OUTER COWL TOP PANEL SUB-ASSEMBLY
REMOVE THROTTLE BODY WITH MOTOR ASSEMBLY
REMOVE VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)
Disconnect the union to vacuum tube hose from the vacuum hose clamp.
Disengage the wire harness clamp.
Disconnect the 2 vacuum hoses.
Disconnect the vacuum switching valve assembly (for ACIS) connector.
Remove the bolt and vacuum switching valve assembly (for ACIS) from the intake manifold.
DISCONNECT NO. 2 VENTILATION HOSE
Slide the clip and disconnect the No. 2 ventilation hose from the intake manifold.
DISCONNECT UNION TO VACUUM TUBE HOSE
Slide the clip and disconnect the union to vacuum tube hose from the intake manifold.
DISCONNECT FUEL TUBE SUB-ASSEMBLY
DISCONNECT ENGINE WIRE
REMOVE FUEL DELIVERY PIPE
REMOVE INTAKE MANIFOLD
Remove the 2 bolts and 2 wire harness clamp brackets from the intake manifold.
Disconnect the fuel vapor feed hose from the intake manifold.
Disengage the 3 wire harness clamps.
Disconnect the sensor wire connector.
Remove the bolt and wire harness clamp bracket from the intake manifold.
Apply positive (+) battery voltage to terminal 8 (M-) and negative (-) battery voltage to terminal 4 (M+) of the sensor wire connector to close the 4 tumble control valves (TCV).
Note
If this procedure is not performed, the 4 tumble control valves (TCV) may be damaged when the intake manifold is removed.
Apply battery voltage for 1 to 3 seconds.
If battery voltage is applied for more than 3 seconds, the intake air control valve actuator (for TCV) may be damaged.
Do not allow the lead wires to contact the other terminals.
Remove the bolt and disconnect the wire harness.
Disengage the 2 wire harness clamps.
Disconnect the intake air control valve actuator (for TCV) connector.
Remove the 6 bolts and intake manifold.
Note
The 4 tumble control valves (TCV) may be damaged if they are not closed before removing the intake manifold.
Tech Tips
Connect the battery to the terminals of the intake air control valve actuator (for TCV) to operate the motor and close the 4 tumble control valves (TCV).
Remove the intake manifold gasket from the intake manifold.
Disconnect the 2 vacuum hoses from the intake manifold and remove the No. 1 check valve.
Remove the bolt and wire harness clamp bracket from the intake manifold.
