2005 NISSAN X-TRAIL sensor

EC-1384
[YD (WITHOUT EURO-OBD)]
TROUBLE DIAGNOSIS

4. CHECK FOR INTAKE AIR LEAK
Listen for an intake air leak after the mass air flow sensor.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace.
5. BLEED AIR FROM FUEL SYSTEM
1. Stop engine.
2. Use priming pump to bleed air from fuel system. Refer to EC-1370, "
AIR BLEEDING" .
>> GO TO 6.
6. CHECK IDLE SPEED AGAIN
With CONSULT-II
1. Start engine and let it idle.
2. Select “CKPS·RPM (TDC)” in “DATA MONITOR” mode with CONSULT-II.
3. Read idle speed.
Without CONSULT-II
Read idle speed.
OK or NG
OK >>INSPECTION END
NG >> GO TO 7.
7. DRAIN WATER FROM FUEL FILTER
Drain water from fuel filter. Refer to EC-1370, "
WATER DRAINING" .
>> GO TO 8. 725±25 rpm
SEF817Y
725±25 rpm
