O2S B1 S1
Heated oxygen sensor output volt-
age for bank 1 sensor 1/
Min.: 0 V, Max.: 1.275 V
Idling: 0.1 to 0.9 V
Performing the INJ VOL or A/F
CONTROL function of the ACTIVE
TEST enables the technician to
check the voltage output of each
sensor
O2S B1 S2
Heated oxygen sensor output volt-
age for bank 1 sensor 2/
Min.: 0 V, Max.: 1.275 V
Idling: 0.1 to 0.9 V
VAPOR PRESS
Vapor pressure/
Min.:
− 4.125 kPa, Max.: 2.125 kPa
Fuel tank cap removed: 0 kPa
Pressure inside the fuel tank can
be read by the vapor pressure
sensor
SHORT FT #1
Short term fuel trim of bank 1/
Min.:
− 100 %, Max.: 100 %
0 ± 20% ⎯
LONG FT #1
Long term fuel trim of bank 1/
Min.:
− 100 %, Max.: 100 %
0 ± 20%
This item is the overall fuel com-
pensation
The long
− term fuel trim is carried
out to compensate a continual
deviation from the theoretical cen-
tral value caused by the short
−
term fuel trim
TOTAL FT #1
Total fuel trim of bank 1:
Average value for fuel trim system
of bank 1/
Min.: 0.5, Max.: 1.496
Idling: 0.5 to 1.4 ⎯
O2FT B1 S1
Short term fuel trim associated
with the bank 1 sensor 2/
Min.:
− 100 %, Max.: 100 %
0
±
20 % Same as SHORT FT #1
O2FT B1 S2
Short term fuel trim associated
with the bank 1 sensor 2/
Min.:
− 100 %, Max.: 100 %
0 ± 20 % Same as SHORT FT #2
FUEL SYS #1
Fuel system status (Bank 1)/
OL or CL or OL DRIVE or
OL FAULT or CL FAULT
Idling after warming up: CLOSED
S OL: Open loop has not yet satis-
fied conditions to go closed loop
S CL: Closed loop using heated ox-
ygen sensor(s) as feed back for
fuel control
S OL DRIVE: Open loop due to
driving conditions (fuel enrich-
ment)
S OL FAULT: Open loop due to de-
tected system fault
S CL FAULT: Closed loop but one
of heated oxygen sensors, which
is used for fuel control, is func-
tioning improperly
FC IDL Fuel cut idle/ON or OFF Fuel cut operating: ON
FC IDL = ”ON” when throttle valve
is fully closed and engine speed is
over 1,500 rpm
O2 LR B1 S1
Response time of the heated oxy-
gen sensor, lean to rich (bank 1
sensor 1)/
Min.: 0 ms, Max.: 16,711 ms
Idling after warming up:
0 to 1,000 m/s
⎯
O2 RL B1 S1
Response time of the heated oxy-
gen sensor, from rich to lean (bank
1 sensor 1)/
Min.: 0 ms, Max.: 16,711 ms
Idling after warming up:
0 to 1,000 m/s
⎯
MIL MIL status/ ON or OFF MIL ON: ON ⎯
