DTC/CIRCUIT DIAGNOSIS

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

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

, 14.25 - 15.12 psi)

• Atmospheric temperature: 20 - 30

C (68 - 86

• Engine coolant temperature: 75 - 95

C (167 - 203

• 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

PERFORM “SPEC” OF “DATA MONITOR” MODE

With CONSULT

NOTE:

Perform “SPEC” in “DATA MONITOR” mode in maximum scale display.

1. Perform

EC-765, "Work Procedure"

2. Select “B/FUEL SCHDL”, “A/F ALPHA-B1” and “MASS AIR FLOW SENSOR (Hz)” in “SPEC” of “DATA

MONITOR” mode of “ENGINE” using CONSULT.

3. Make sure that monitor items are within the SP value.

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.
