DTC P0420 THREE WAY CATALYST FUNCTIONPFP:20905
On Board Diagnosis LogicEBS010Q8
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 ProcedureEBS010Q9
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:

Open engine hood before conducting the following procedure.

Do not hold engine speed for more than the specified minutes below.
1. Start Engine and warm it up to the normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and keep the engine speed between 3,500 and 4,00 rpm for at least 1 minute under no load.
4. Let engine idle for 1 minute.
5. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUP-
PORT” mode with CONSULT-II.
6. Start engine.
7. 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 10
8. Wait 5 seconds at idle.

GENERAL MAINTENANCE

GENERAL MAINTENANCEPFP: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-12
, BL-18
Tire rotationTires should be rotated every 5,000 km (3,000 miles).MA-41
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.MA-45
Item Reference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. —
Engine coolant levelCheck the coolant level when the engine is cold.MA-20

Brake and clutch fluid
levelsMake sure that the brake and clutch fluid levels are between the “MAX” and
“MIN” lines on the reservoir.MA-37
, MA-41
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN”
lines.—
