Pathfinder 2WD V6-4.0L (VQ40DE) (2009)
CONSULT-III and it is directed according to inspection procedure of Engine Control System. Refer to See: Powertrain
Management/Computers and Control Systems/Testing and Inspection/Diagnostic Trouble Code Tests and Associated Procedures/P Code
Charts/P0011.
1. Check the engine oil level. Refer to See: Engine Lubrication/Engine Oil/Testing and Inspection.
2. Perform the following procedure so as to prevent the engine from being unintentionally started while checking.
a. Release fuel pressure. Refer to See: Powertrain Management/Fuel Delivery and Air Induction/Testing and Inspection/Component Tests and
General Diagnostics/Fuel Pressure Check.
b. Disconnect ignition coil and injector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to See: Timing Components/Timing Cover/Service and Repair/Front Timing Chain Case
.
4. Crank the engine, and then make sure that engine oil comes out from camshaft bracket (No. 1) 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 intake valve timing control solenoid valve installation hole during cranking. Use a shop cloth to prevent the
engine components and the vehicle.
-
Do not allow engine oil to get on rubber components such as drive belt or engine mount insulators. Immediately wipe off any splashed
engine oil.
-
Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from camshaft bracket (No. 1)
oil hole. Refer to See: Engine Lubrication/Diagrams/Lubrication Circuit, See: Engine Lubrication/Diagrams/Schematic.
5. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT), and then check each oil groove for
clogging.
-
Clean oil groove if necessary. Refer to See: Engine Lubrication/Diagrams/Lubrication Circuit, See: Engine Lubrication/Diagrams/Schematic.
6. After inspection, installation of the remaining components is in the reverse order of removal.
Inspection for Leaks
-
Before starting the engine, check oil/fluid levels including engine coolant and engine oil. If the levels are lower than required quantity, fill to the
specified level. Refer to See: Maintenance.
-
Use procedure below to check for fuel leakage.
-
Turn ignition switch ON (with engine stopped). With fuel pressure applied to the fuel piping, check for fuel leakage at the connection points.
-
Start engine. With engine speed increased, check 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 and 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, exhaust gas, or any oil/fluids including engine oil and engine coolant.
-
Bleed air from passages in lines and hoses, such as in cooling system.
-
After cooling down the engine, again check oil/fluid levels including engine oil and engine coolant. Refill to specified level if necessary.
