NISSAN TIIDA 2007 Service Repair Manual

EC-392
< BASIC INSPECTION >[HR16DE (WITHOUT EURO-OBD)]
INSPECTION AND ADJUSTMENT
5.DETECT MALFUNCTIONING PART
Check the following
 Check that throttle valve is fully closed.
 Check PCV valve operation.
 Check that downstream of throttle valve is free from air leakage.
Is the inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace malfunctioning part.
6.DETECT MALFUNCTIONING PART
Engine component parts and their installation condition are questionable. Check and eliminate the cause of
the incident.
It is useful to perform “TROUBLE DIAGNOSIS - SPECIFICATION VALUE”. Refer to EC-469, "
Description".
If any of the following conditions occur after the engine has started, eliminate the cause of the incident and
perform Idle Air Volume Learning all over again:
 Engine stalls.
 Erroneous idle.

MIXTURE RATIO SELF-LEARNING VALUE CLEAR
MIXTURE RATIO SELF-LEARNING VALUE CLEAR : DescriptionINFOID:0000000001161442
This describes how to erase the mixture ratio self-learning value. For the actual procedure, follow the instruc-
tions in “Diagnosis Procedure”.
MIXTURE RATIO SELF-LEARNING VALUE CLEAR : Special Repair Requirement
INFOID:0000000001161443
1.START
With CONSULT-III
1. Start engine and warm it up to normal operating temperature.
2. Select “SELF-LEARNING CONT” in “WORK SUPPORT” mode with CONSULT-III.
3. Clear mixture ratio self-learning value by touching “CLEAR”.
Without CONSULT-III
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF.
3. Disconnect mass air flow sensor harness connector, and restart and run engine for at least 5 seconds at
idle speed.
4. Stop engine and reconnect mass air flow sensor harness connector.
5. Make sure that DTC P0102 is displayed.
6. Erase the DTC memory. Refer to EC-457, "
Diagnosis Description".
7. Make sure that DTC P0000 is displayed.
