FUEL SYSTEM B1 (FUEL SYSTEM BANK 1
STATUS)
FUEL SYSTEM B2 (FUEL SYSTEM BANK 2
STATUS)
Air / fuel ratio feedback loop status displayed as one
of the followings.
OPEN: Open loop-has not yet satisfied conditions to
go closed loop.
CLOSED: Closed loop-using oxygen sensor(s) as
feedback for fuel control.
OPEN-DRIVE COND: Open loop due to driving
conditions (Power enrichment, etc.).
OPEN SYS FAULT: Open loop due to detected sys-
tem fault.
CLOSED-ONE O2S: Closed loop, but fault with at
least one oxygen sensor-may be using single oxygen
sensor for fuel control.
CALC LOAD (CALCULATED LOAD VALUE, %)
Engine load displayed as a percentage of maximum
possible load. Value is calculated mathematically us-
ing the formula: actual (current) intake air volume
B
maximum possible intake air volume x 100%.
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.
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.
VEHICLE SPEED (km/h, MPH)
It is computed based on pulse signals from vehicle
speed sensor in combination meter.
FUEL CUT (ON/OFF)
ON: Fuel being cut. (output signal to injector is
stopped.)
OFF: Fuel not being cut.
MAP (MANIFOLD ABSOLUTE PRESSURE,
mmHg, kPa)
This parameter indicates the pressure in the intake
manifold absolute pressure.
EGR VALVE (%)
This parameter indicates opening rate of EGR valve
which controls the amount of EGR flow.
A/C SWITCH (ON/OFF)
ON: Command for operation being output from A/C
amplifier to compressor.
OFF: Command for operation not being output.
PSP SWITCH (ON/OFF)
ON: PSP switch detects P/S operation. (high PS
pressure)
OFF: PSP switch not detects P/S operation.
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.
FUEL TANK LEVEL (%)
This parameter indicates approximate fuel level in the
fuel tank. As the detectable range of the fuel level sen-
sor is set as 0 to 100%, however, with some models
whose fuel tank capacity is smaller, the indicated fuel
level may be only 70% even when the fuel tank is full.
ELECTRIC LOAD (ON / OFF)
ON: Small light switch ON or rear window defogger
switch ON.
OFF: Small light switch OFF and rear window defog-
ger switch OFF.
VSS (4-A/T) (km/h, MPH)
It is computed by using pulse signals from vehicle
speed sensor on 4-speed automatic transmission.
