9. Start engine and let it idle.
10. Wait 20 seconds.
>> GO TO 4.
4.CHECK IDLE SPEED AND IGNITION TIMING
Rev up the engine 2 or 3 times and check that idle s peed and ignition timing are within the specifications.
For procedure, refer to EC-992, "Work Procedure"
and EC-993, "Work Procedure".
For specifications, refer to EC-998, "Idle Speed"
and EC-998, "Ignition Timing".
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 5.
5.DETECT MALFUNCTIONING PART-I
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-II
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-701, "Description"
.
If any of the following conditions occur after the engi ne has started, eliminate the cause of the incident and
perform Idle Air Volume Learning again:
• Engine stalls.
• Incorrect idle.

FUEL PRESSURE CHECK
CAUTION:
• The fuel hose connection method used when taki ng fuel pressure check must not be used for other
purposes.
• Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
• Be careful not to scratch or get the fuel hose conn ection area dirty when servicing, so that the quick
connector o-ring ma intains seal ability.
• Use Fuel Pressure Gauge Kit [SST: — (J-44321)] an d Fuel Pressure Adapter [SST: — (J-44321-6)] to
check fuel pressure.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because th is models do not have fuel return system.
1.FUEL PRESSURE CHECK
1. Release fuel pressure to zero.
2. Remove fuel hose using Quick Connector Release [SST: — (J-45488)]. CAUTION:
• Do not twist or kink fuel hose because it is plastic hose.
• Do not remove fuel hose from quick connector.
• Keep fuel hose connections clean.
3. Install Fuel Pressure Adapter [SST: — (J-44321-6)] (B) and Fuel Pressure Gauge kit [SST: — (J44321)] (A) as shown in figure.
CAUTION:
• Do not distort or bend fuel rail tube when installing fuel
pressure gauge adapter.
• When reconnecting fuel hose, check the original fuel hose
(1) for damage and abnormality.
4. Turn ignition switch ON (reactivate fuel pump) and check for fuel leakage.
5. Start engine and check for fuel leakage.
6. Read the indication of fuel pressure gauge kit [SST: — (J- 44321)].
CAUTION:
• During fuel pressure check, check for fuel leakage from fuel connection every 3 minutes.

TROUBLE DIAGNOSIS - SPECIFICATION VALUE
DescriptionINFOID:0000000009462570
The specification (SP) value indicates the tolerance of
the value that is displayed in “SPEC” in “DATA MONI-
TOR” mode of CONSULT during normal operation of the Engine Control System. When the value in “SPEC” in
“DATA MONITOR” mode is within the SP value, the E ngine Control System is confirmed OK. When the value
in “SPEC” in “DATA MONITOR” mode is NOT within t he SP value, the Engine Control System may have one
or more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not illuminate
the MIL.
The SP value will be displayed for the following three items:
• B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc- tion)
• A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)
• MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)
Component Function CheckINFOID:0000000009462571

2, 14.25 - 15.12 psi)
• Atmospheric temperature: 20 - 30 °C (68 - 86 °F)
• Engine coolant temperature: 75 - 95 °C (167 - 203 °F)
• Transmission: Warmed-up
- After the engine is warmed up to normal operating tem perature, drive vehicle until “FLUID TEMP SE” (CVT
fluid temperature sensor signal) indicates more than 60 °C (140 °F).
