REQUIRED TOOLS AND MATERIALS:

REPAIR PROCEDURE:
1. Inspect the condition of the valve cover oil baffle as per "TSB 1077" if camshaft or camshaft position sensor damage resulting from a bent baffle is identified, repair the damage as necessary.
2. Make sure the vehicle is in "PARK" with the engine idling.







3. Referring to the screen flow below, connect the Toyota Handheld Diagnostic Tester to the vehicle and select the VVT Control Bank One Active Test (VVT CTRL B1) from the Active Test Menu.
4. Using the right arrow key, toggle the VVTi actuator "ON."
5. If at this point the vehicle does not run rough and/or stall when the active test is performed, proceed with Repair Manual P1349 VVTi Fault Isolation Procedure (FIP).

If the vehicle does stall and/or run rough, this indicates the the VVTi control system is operating. Proceed to replace the VVTi actuator following the repair procedures listed on the ETAS Library: Engine Mechanical Section, Camshaft, Replacement.

Service Tip:
Camshaft Timing Gear Assembly Installation







a) The camshaft timing gear should come in the unlocked position from the factory. If it is difficult to install the camshaft timing gear, the lock pin may be engaged. To disengage the lock pin, apply and hold approximately 20 psi of air pressure at the oil feed hole located 90 degrees clockwise of the oval slot. (See Figure 1.)

Once the pin has released, turn the interior assembly counterclockwise. (See black arrow in Figure 1.)







b) Put the camshaft timing gear assembly and the camshaft together with the straight pin off the key groove.

c) Turn the camshaft timing gear assembly (as shown in Figure 2) while pushing it lightly against the camshaft. Push further at the position where the pin fits into the groove.

NOTE:
Be sure not to turn the camshaft timing gear to the retard angle side (in the clockwise direction).

d) Check that there is no clearance between the end of the camshaft and the camshaft timing gear.
e) Tighten the camshaft bolt with the camshaft timing gear fixed.
Torque: 54 N-m (551 kgf-cm, 40 ft-lbf)

f) Check that the camshaft timing gear assembly can move to the retard angle side (in the clockwise direction), and is locked at the most retarded position.
