4. Disconnect harness connector at oil pressure switch, and using
deep socket (commercial service tool), remove oil pressure
switch.
5. Install the oil pressure gauge and hose (special service tool).
6. After warming up engine, make sure that oil pressure corresponding to the engine speed is produced.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
7. After checking, install oil pressure switch as follows.
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine Thread Sealant or equivalent.
c. After warming up engine, check for oil leakage with running engine.
Changing Engine OilEBS00B04
WARNING:

Be careful not to burn yourself, as the engine oil is hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine oil leakage from engine components. Refer
to LU-20, "
ENGINE OIL LEAKAGE" .
2. Stop engine and wait for 10 minutes.

TROUBLE DIAGNOSIS

17. DETECT MALFUNCTIONING PART
Check the following.

Check camshaft position sensor (PHASE) and circuit. Refer to EC-254 .

Check crankshaft position sensor (POS) and circuit. Refer to EC-247 .
OK or NG
OK >> GO TO 18.
NG >> 1. Repair or replace.
2. GO TO 4.
18. CHECK ECM FUNCTION
1. Substitute another known-good ECM to check ECM function. (ECM may be the cause of an incident, but
this is a rare case.)
2. Perform initialization of NATS system and registration of all NATS ignition key IDs. Refer to EC-64, "
NATS
(Nissan Anti-theft System)" .
>> GO TO 4.
