DTC P0420 THREE WAY CATALYST FUNCTIONPFP:20905
On Board Diagnosis LogicEBS00B6A
The ECM monitors the switching frequency ratio of heated oxygen
sensors 1 and 2.
A three way catalyst (Manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of heated oxygen sensors 1 and 2
approaches a specified limit value, the three way catalyst (Manifold)
malfunction is diagnosed.
DTC Confirmation ProcedureEBS00B6B
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
TESTING CONDITION:
lOpen engine hood before conducting the following procedure.
lDo not hold engine speed for more than the specified minutes below.
1. Turn ignition switch “ON”.
2. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUP-
PORT”modewithCONSULT-II.
3. Start engine.
4. Rev engine up to 2,000 to 3,000 rpm and hold it for 3 consecu-
tive minutes then release the accelerator pedal completely.
If "INCMP" of "CATALYST" changed to "COMPLT", go to step 7
5. Wait 5 seconds at idle.

lIf some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
–If the added engine oil improves the compression, the piston rings may be worn out or damaged. Check
the piston rings and replace if necessary.
–If the compression pressure remains at low level despite the addition of engine oil, the valves may be mal-
functioning. Check the valves for damage. Replace the valve or valve seat accordingly.
lIf two adjacent cylinders have respectively low compression pressure and their compression remains low
even after the addition of engine oil, the gaskets are leaking. In such a case, replace the cylinder head
gaskets.
8. Install spark plug, ignition coil and harness connectors.

HOW TO USE THIS MANUAL
lignition switch is “OFF”,
ldoors, hood and trunk lid/back door are closed,
lpedals are not depressed, and
lparking brake is released.
Detectable Lines and Non-detectable Lines
In some wiring diagrams, two kinds of lines, representing wires, with different weight are used.
lA line with regular weight (wider line) represents a “detectable
line for DTC (Diagnostic Trouble Code)”. A “detectable line for
DTC” is a circuit in which ECM can detect its malfunctions with
the on board diagnostic system.
lA line with less weight (thinner line) represents a “non-detect-
able line for DTC”. A “non-detectable line for DTC” is a circuit in
which ECM cannot detect its malfunctions with the on board
diagnostic system.
Multiple Switch
The continuity of multiple switch is described in two ways as shown below.
lThe switch chart is used in schematic diagrams.

GENERAL MAINTENANCE
GENERAL MAINTENANCE
PFP:00000
General MaintenanceELS000AL
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station, includ-
ing the spare, and adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate prop-
erly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch keeps the hood from opening when the primary latch is
released.
When driving in areas using road salt or other corrosive materials, check for
lubrication frequently.BL-4
,BL-8
Tire rotationTires should be rotated every 5,000 km (3,000 miles).MA-38
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.SB-3
Item Reference page
