TROUBLE DIAGNOSIS - SPECIFICATION VALUE
Description
INFOID:0000000012198288
The specification (SP) value indicates the tolerance of the value that is displayed in “SPEC” of “DATA MONI-
TOR” mode of CONSULT during normal operation of the Engine Control System. When the value in “SPEC” of
“DATA MONITOR” mode is within the SP value, the Engine Control System is confirmed OK. When the value
in “SPEC” of “DATA MONITOR” mode is NOT within the 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 light 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 (The mean value of air-fuel ratio feedback correction factor per cycle)
• MASS AIR FLOW SENSOR (Hz) (The signal frequency of the mass air flow sensor)
Component Function Check
INFOID:0000000012198289
1.
START
Make sure that all of the following conditions are satisfied.
• Vehicle driven distance: More than 5,000 km (3,107 miles)
• Barometric pressure: 98.3 - 104.3 kPa (1.003 - 1.064 kg/cm
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
- CVT models: After the engine is warmed up to normal operating temperature, drive vehicle until “FLUID
TEMP SE” (CVT fluid temperature sensor signal) indicates more than 60
°
C (140
°
F).
- M/T models: After the engine is warmed up to normal operating temperature, drive vehicle for 5 minutes.
• Electrical load: Not applied
- Rear window defogger switch, air conditioner switch, lighting switch are OFF. Steering wheel is straight
ahead.
• Engine speed: Idle

TROUBLE DIAGNOSIS - SPECIFICATION VALUE
NOTE:
Check “A/F ALPHA-B1” for approximately 1 minute because it may fluctuate. It is NG if the indication is
out of the SP value even a little.
Is the measurement value within the SP value?
YES
>> GO TO 14.
NO-1 >> Less than the SP value: GO TO 2.
NO-2 >> More than the SP value: GO TO 3.
2.
CHECK “B/FUEL SCHDL”
Select “B/FUEL SCHDL” in “SPEC” of “DATA MONITOR” mode, and make sure that the indication is within the
SP value.
Is the measurement value within the SP value?
YES
>> GO TO 4.
NO
>> More than the SP value: GO TO 16.
3.
CHECK “B/FUEL SCHDL”
Select “B/FUEL SCHDL” in “SPEC” of “DATA MONITOR” mode, and make sure that the indication is within the

NO-2 >> Less than the SP value: GO TO 22.
4.
CHECK “A/F ALPHA-B1”
1. Stop the engine.
2. Disconnect PCV hose, and then plug it.
3. Start engine.
4. Select “A/F ALPHA-B1” in “SPEC” of “DATA MONITOR” mode, and make sure that the indication is within
the SP value.
Is the measurement value within the SP value?
YES
>> GO TO 5.
NO
>> GO TO 6.
5.
CHANGE ENGINE OIL
1. Stop the engine.
2. Change engine oil.
NOTE:
This symptom may occur when a large amount of gasoline is mixed with engine oil because of driving
conditions (such as when engine oil temperature does not rise enough since a journey distance is too
short during winter). The symptom will not be detected after changing engine oil or changing driving con-
dition.

DETECT MALFUNCTIONING PART
Check the following.
1. Ignition coil and its circuit (Refer to
EC-1229, "Component Function Check"
2. Fuel injector and its circuit (Refer to
EC-1204, "Component Function Check"
.)
3. Intake air leakage
