Scan Tool Data Definitions
COOLANT TEMP (ENGINE COOLANT
TEMPERATURE,
°
C,
°
F)
It is detected by engine coolant temp. sensor.
INTAKE AIR TEMP. (
°
C,
°
F)
It is detected by intake air temp. sensor.
ENGINE SPEED (rpm)
It is computed by reference pulses from the camshaft
position sensor.
DESIRED 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, this number is not valid.
