Fluids and Lubricants " .
• Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and
engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
• Perform this inspection only when DTC P0011 is de tected in self-diagnostic results of CONSULT-III
and it is directed according to inspect ion procedure of EC section. Refer to EC-133, " Diagnosis Pro-
cedure " .
• Check when engine is cold so as to pr event burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-7, " Inspection " .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release the fuel pressure. Refer to EC-498, " Inspection " .
b. Remove intake manifold. Refer to EM-28, " Exploded View " .
c. Disconnect ignition coil and injector harness connectors. Refer to EM-46, " Exploded View " .
3. Remove intake valve timing control solenoid valve. Refer to EM-49, " Exploded View " .
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End
crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Prevent splashing by using a shop cloth so as to prevent
the worker from injury from engine oil an d so as to prevent engine oil contamination.
• Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engi ne oil off immediately if it is splashed.
