18.DETECT MALFUNCTIONING PART
1. Check for the cause of large engine friction. Refer to the following.
- Engine oil level is too high
- Engine oil viscosity
- Belt tension of power steering, alternator, A/C compressor, etc. is excessive
- Noise from engine
- Noise from transmission, etc.
2. Check for the cause of insufficient combustion. Refer to the following.
- Valve clearance malfunction
- Intake valve timing control function malfunction
- Camshaft sprocket installation malfunction, etc.
>> Repair or replace malfunctioning part, and then GO TO 30.
19.CHECK INTAKE SYSTEM
Check for the cause of uneven air flow through mass air flow sensor. Refer to the following.
 Crushed air ducts
 Malfunctioning seal of air cleaner element
 Uneven dirt of air cleaner element
 Improper specification of intake air system
OK or NG
OK >> GO TO 21.
NG >> Repair or replace malfunctioning part, and then GO TO 20.
20.CHECK “A/F ALPHA-B1”, “A/F ALPHA-B2”, AND “B/FUEL SCHDL”
Select “A/F ALPHA-B1”, “A/F ALPHA-B2”, and “B/F UEL SCHDL” in “SPEC” of “DATA MONITOR” mode, and
make sure that the each indication is within the SP value.
OK or NG
OK >> INSPECTION END
NG (“B/FUEL SCHDL” is more, “A/F ALPHA-B1”, “A /F ALPHA-B2” are less than the SP value)>>GO TO 21.
21.DISCONNECT AND RECONNECT MASS AIR FLOW SENSOR HARNESS CONNECTOR
1. Stop the engine.

*1: For further details, refer to MA-13, "Engine Oil Recommendation".
*2: If Genuine NISSAN Matic S ATF is not available, Genuine Matic J ATF may also be used. Using automatic transmission fluid
other than Genuine NISSAN Matic S ATF or Matic J ATF will cause deterioration in drivability and automatic transmission dura-
bility, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited warranty.
*3: DEXRON
TM VI type ATF may also be used.
*4: Available in mainland U.S.A. through an INFINITI dealer.
*5: For further details, see “Air conditioner specification label”.
*6: For hot climates, viscosity SAE 90 is suitable for ambient te mperatures above 0° C (32 ° F).
*7: For improved vehicle performance, INFINITI recommends the use of unleaded premium gasoline with an octane rating of at leas t 91
AKI (RON 96). For further details, refer to GI-27, "
Precaution for Fuel (Unleaded Premium Gasoline Recommended)",
*8: See an INFINITI dealer for service for synthetic oil.
*9: Using fluid other than Genuine Nissan Matic D ATF may cause deterioration in drivability and transfer durability, and may d amage the
transfer, which is not covered by the (INFINITI new vehicle limited) warranty. Description

Engine Oil RecommendationINFOID:0000000003776985
NISSAN recommends the use of an energy conserving oil in order to
improve fuel economy. Select only
engine oils that meet the Ameri-
can Petroleum Institute (API) cert ification and International Lubricant
Standardization and Approval Committee (ILSAC) certification and
SAE viscosity standard (2). These oils have the API certification
mark (1) on the front of the container. Oils which do not have the
specified quality label should not be used as they could cause
engine damage.
ANTI-FREEZE COOLANT MIXTURE RATIO
The engine cooling system is filled at the factory wit h a high-quality, long life, year-round, anti-freeze coolant
solution. The anti-freeze solution contains rust and corrosion inhibitors. Therefore, additional cooling system
additives are not necessary.
CAUTION:
• When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Anti-freeze cool-
ant or equivalent with the proper mixture ratio of 50% anti-freeze and 50% demineralized water or
distilled water.
• Other types of coolant solutions may damage your cooling system.
