shaft hexagonal part if mounting space is small.
b. Remove the stopper pin and release the plunger to apply ten-
sion to the timing chain.
c. Install the chain tensioner cover onto the front cover.
• Apply liquid gasket as shown.
Use Genuine RTV Silicone Sealant or equivalent. Refer to

• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT III
and it is directed according to inspection procedure of EC section. Refer to
1. Check engine oil level. Refer to
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to
.
b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove IVT control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from IVT control cover oil hole. End cranking
after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
CAUTION:
• Engine oil may squirt from IVT control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engine oil from splashing on worker, engine components and vehicle.
• Do not allow engine oil to get on rubber components such as drive belts or engine mount insula-
tors. Immediately wipe off any splashed engine oil.
5. Clean oil groove between oil strainer and IVT control solenoid valve if engine oil does not come out from
IVT control valve cover oil hole. Refer to
.
6. Remove components between IVT control solenoid valve and camshaft sprocket (INT), and then check
each oil groove for clogging.
• Clean oil groove if necessary.
7. After inspection, installation of the remaining components is in the reverse order of removal.
