DTC P0447 EVAP CANISTER VENT CONTROL VALVEPFP:14935
Component DescriptionUBS00QIG
The EVAP canister vent control valve (3) is located on the EVAP
canister (2) and is used to seal the canister vent.
This solenoid valve responds to signals from the ECM. When the
ECM sends an ON signal, the coil in the solenoid valve is energized.
A plunger will then move to seal the canister vent. The ability to seal
the vent is necessary for the on board diagnosis of other evaporative
emission control system components.
This solenoid valve is used only for diagnosis, and usually remains
opened.
When the vent is closed, under normal purge conditions, the evapo-
rative emission control system is depressurized and allows EVAP
control system diagnoses.

PRECAUTIONS
2007 Versa
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for Drain CoolantEBS00U6S

Drain coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS00U6T

Before starting work, make sure no fire or spark producing items are in the work area.

Release fuel pressure before disassembly.

After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyEBS00U6U

When instructed to use special service tools, use the specified tools. Always be careful to work safely,
avoid forceful or uninstructed operations.

Exercise maximum care to avoid damage to mating or sliding surfaces.

Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.

Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.

When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be
used where noted in the step.
Precautions for Inspection, Repair and ReplacementEBS00U6V

Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way,
and replace if necessary.
Precautions for Assembly and InstallationEBS00U6W

Use torque wrench to tighten bolts or nuts to specification.

When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.

Replace with new gasket, packing, oil seal or O-ring.

Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.

Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.

Release air within route after draining coolant.

Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine
stopped). Then make sure that there are no leaks at fuel line connections.

After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems
for leakage.
Parts Requiring Angular TighteningEBS00U6X

Use an angle wrench for the final tightening of the following engine parts:
–Cylinder head bolts
–Camshaft sprocket (INT)
–Main bearing cap bolts
–Connecting rod cap nuts
–Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)

Revision: June 20062007 Versa

Do not use a torque value for final tightening.

The torque value for these parts are for a preliminary step.

Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions for Liquid GasketEBS00U6Y
REMOVAL OF LIQUID GASKET SEALING

After removing the bolts and nuts, separate the mating surface
and remove the sealant using Tool.
CAUTION:
Be careful not to damage the mating surfaces.

In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap (1) the cutter where the RTV Silicone Sealant is
applied. Use a plastic hammer to slide the cutter (2) by tapping
on the side.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old Silicone RTV Sealant adhering
to the gasket application surface and the mating surface.

Remove the sealant completely from the groove of the gasket
application surface, bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating
surface and remove adhering moisture, grease and foreign
materials.
3. Attach the sealant tube to the tube presser.
Use Genuine Silicone RTV Sealant or equivalent. Refer to
GI-46, "
Recommended Chemical Products and Sealants" .
4. Apply the sealant without breaks to the specified location using
Tool.

If there is a groove for the sealant application, apply the seal-
ant to the groove.

As for the bolt holes, normally apply the sealant inside the
holes. If specified, it should be applied outside the holes.
Make sure to read the text of this manual.

Within five minutes of the sealant application, install the mat-
ing component.

If the sealant protrudes, wipe it off immediately.

Do not retighten after the installation.

After 30 minutes or more have passed from the installation, fill
the engine with the specified oil and coolant. Refer to MA-11,
"Fluids and Lubricants" . Tool number : KV10111100 (J-37228)
