ENGINE GENERAL INFORMATION AND DIAGNOSIS (G16/J20 ENGINES) 6-29
Scan Tool Data Definitions
COOLANT TEMP (ENGINE COOLANT TEMP., °C/°F)
It is detected by engine coolant temp. sensor.
INTAKE AIR TEMP (°C/°F)
It is detected by intake air temp. sensor.
DESIRE IDLE (DESIRED IDLE SPEED RPM)
The desired idle speed is an ECM internal parameter which indicates the ECM requested idle. If the engine is
not running, the number is not valid.
CLOSED THROT POS (CLOSED THROTTLE POSITION ON/OFF)
This parameter will read ON when the throttle valve is fully closed, or OFF when the throttle is not fully closed.
IAC FLOW DUTY (%)
This parameter indicates IAC valve opening rate which controls bypass air flow.
VEHICLE SPEED (km/h, MPH)
It is computed based on pulse signals from vehicle speed sensor on transfer or transmission.
SHORT FT B1 (SHORT TERM FUEL TRIM, %)
Short term fuel trim value represents short term corrections to the air/fuel mixture computation. A value of 0 indi-
cates no correction, a value greater than 0 means an enrichment correction, and a value less than 0 implies an
enleanment correction.
LONG FT B1 (LONG TERM FUEL TRIM, %)
Long term fuel trim value represents long term corrections to the air/fuel mixture computation. A value of 0 indi-
cates no correction, a value greater than 0 means an enrichment correction, and a value less than 0 implies an
enleanment correction.
IGNITION ADVANCE (IGNITION TIMING ADVANCE FOR NO.1 CYLINDER, °)
Ignition timing of No.1 cylinder is commanded by ECM. The actual ignition timing should be checked by using
the timing light.
ENGINE SPEED (RPM)
It is computed by reference pulses from the Camshaft Position Sensor.
MODE SELECT SW
(Power/Normal Change
Switch) Ignition switch ON, P/N change switch is
at normal position. NORMAL
✱
Ignition switch ON, P/N change switch is
at power position. POWER
4WD-L SW
(4WD Low Switch) Ignition switch ON, Transfer lever is shifted
at “4H” or “2H” position. OFF
✱
Ignition switch ON, Transfer lever is shifted
at “4L” position. ON
