DescriptionEBS00KF3
The specification (SP) value indicates the tolerance of the value that is displayed in “DATA MONITOR (SPEC)”
mode of CONSULT-II during normal operation of the Engine Control System. When the value in “DATA MONI-
TOR (SPEC)” mode is within the SP value, the Engine Control System is confirmed OK. When the value in
“DATA MONITOR (SPEC)” 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
MI.
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 cor-
rection)
●A/F ALPHA-B1 (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)
Testing ConditionEBS00KF4
●Vehicle driven distance: More than 5,000 km (3,017 miles)
●Barometric pressure: 98.3 - 104.3 kPa (0.983 - 1.043 bar, 1.003 - 1.064 kg/cm2 , 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*1
●Electrical load: Not applied*2
●Engine speed: Idle
*1: For A/T models, after the engine is warmed up to normal operating temperature, drive vehicle until “FLUID
TEMP SE” (A/T fluid temperature sensor signal) indicates more than 60°C (140°F).
For M/T models, after the engine is warmed up to normal operating temperature, drive vehicle for 5 minutes.
*2: Rear window defogger switch, air conditioner switch, lighting switch are “OFF”. Steering wheel is straight
