ENGINE DIAGNOSIS (G16 / J20 ENGINES) 6-25
TOTAL FUEL TRIM (%)
The value of total fuel trim is obtained by putting val-
ues of short term fuel trim and long term fuel trim to-
gether. This value indicates how much correction is
necessary to keep the air/fuel mixture stoichiomet-
rical.
MAP (MANIFOLD ABSOLUTE PRESSURE,
mmHg, kPaA)
It is detected by manifold absolute pressure sensor.
BAROMETRIC PRESS (kPa, inHg)
This parameter represents a measurement of baro-
metric air pressure and is used for altitude correction
of the fuel injection quantity and IAC valve control.
CANIST PRG DUTY (EVAP CANISTER PURGE
FLOW DUTY, %)
This parameter indicates valve ON (valve open) time
rate within a certain set cycle of EVAP canister purge
valve which controls the amount of EVAP purge.
FUEL TANK LEVEL (%)
This parameter indicates approximate fuel level in the
fuel tank.
FUEL PUMP (ON / OFF)
ON is displayed when the ECM (or PCM) activates the
fuel pump via the fuel pump relay switch.
FUEL CUT (ON / OFF)
ON: Fuel being cut (output signal to injector is
stopped).
OFF: Fuel not being cut.
EGR VALVE (%)
This parameter indicates opening rate of EGR valve
which controls the amount of EGR flow.
PSP SWITCH (ON / OFF)
ON: PSP switch detects P/S operation (high PS
pressure).
OFF: PSP switch not detects P/S operation.
A/ C SWITCH (ON / OFF)
ON: Command for operation being output from A/C
amplifier to compressor.
OFF: Command for operation not being output.
PNP SIGNAL (TRANSMISSION RANGE
SWITCH, P/N or D range)
Whether the transmission range switch (P/N position
switch) at P or N range or at R, D, 2 or L range is dis-
played. If at P or N range, “P/N range” is displayed and
if at R, D, 2 or L range, “D range” is displayed.
A/ C CONDENSER FAN (ON / OFF)
This parameter indicates the state of the A / C Con-
denser Fan control signal.
ELECTRIC LOAD (ON / OFF)
ON: Headlight, small light, heater fan or rear window
defogger ON signal inputted.
OFF: Above electric loads all turned OFF.
BRAKE SW (ON / OFF)
This parameter indicates the state of the brake
switch.
BLOWER FAN (ON / OFF)
This parameter indicates the state of the blower fan
motor switch.
