DIAG TROUBLE
CODE
[PXXXX]
The engine control component part/control system has a trouble code, it is displayed as PXXXX. (Refer to
EC-676, "
INDEX FOR DTC" .)
FUEL SYS-B1
“Fuel injection system status” at the moment a malfunction is detected is displayed.
One mode in the following is displayed.
Mode2: Open loop due to detected system malfunction
Mode3: Open loop due to driving conditions (power enrichment, deceleration enleanment)
Mode4: Closed loop - using oxygen sensor(s) as feedback for fuel control
Mode5: Open loop - has not yet satisfied condition to go to closed loop
FUEL SYS-B2
CAL/LD VALUE [%]
The calculated load value at the moment a malfunction is detected is displayed.
COOLANT TEMP [ °C]
or [ °F]
The engine coolant temperature at the moment a malfunction is detected is displayed.
L-FUEL TRM-B1 [%]
“Long-term fuel trim” at the moment a malfunction is detected is displayed.
The long-term fuel trim indicates much more gradual feedback compensation to the base fuel schedule
than short-term fuel trim.
L-FUEL TRM-B2 [%]
S-FUEL TRM-B1 [%]
“Short-term fuel trim” at the moment a malfunction is detected is displayed.
The short-term fuel trim indicates dynamic or instantaneous feedback compensation to the base fuel
schedule.
S-FUEL TRM-B2 [%]
ENGINE SPEED
[rpm]
The engine speed at the moment a malfunction is detected is displayed.
VEHICL SPEED
[km/h] or [mph]
The vehicle speed at the moment a malfunction is detected is displayed.

NALS Description Remarks
ENG SPEED [rpm] ××
Indicates the engine speed computed
from the signal of the crankshaft position
sensor (POS) and camshaft position sen-
sor (PHASE).Accuracy becomes poor if engine speed
drops below the idle rpm.
If the signal is interrupted while the
engine is running, an abnormal value may
be indicated.
MAS A/F SE-B1 [V] ××
The signal voltage of the mass air flow
sensor is displayed.When the engine is stopped, a certain
value is indicated.
B/FUEL SCHDL
[msec] ×
“Base fuel schedule” indicates the fuel
injection pulse width programmed into
ECM, prior to any learned on board cor-
rection.
A/F ALPHA-B1 [%] ×
The mean value of the air-fuel ratio feed-
back correction factor per cycle is indi-
cated.When the engine is stopped, a certain
value is indicated.
This data also includes the data for the
air-fuel ratio learning control.
A/F ALPHA-B2 [%]
×
COOLAN TEMP/S
[ ° C] or [ °F] ××
The engine coolant temperature (deter-
mined by the signal voltage of the engine
coolant temperature sensor) is displayed.
When the engine coolant temperature
sensor is open or short-circuited, ECM
enters fail-safe mode. The engine coolant
temperature determined by the ECM is
displayed.
A/F SEN1 (B1) [V] ××
The A/F signal computed from the input
signal of the air fuel ratio (A/F) sensor 1 is
displayed.
A/F SEN1 (B2) [V]
×
HO2S2 (B1) [V] ×
The signal voltage of the heated oxygen
sensor 2 is displayed.
HO2S2 (B2) [V] ×
HO2S2 MNTR (B1)
[RICH/LEAN] ×
Display of heated oxygen sensor 2 signal:
RICH: means the amount of oxygen after
three way catalyst is relatively small.
LEAN: means the amount of oxygen after
three way catalyst is relatively large.
When the engine is stopped, a certain
value is indicated.
HO2S2 MNTR (B2)
[RICH/LEAN] ×
VHCL SPEED SE
[km/h] or [mph] ××
The vehicle speed computed from the
vehicle speed signal sent from combina-
tion meter is displayed.
BATTERY VOLT
[V] ××
The power supply voltage of ECM is dis-
played.
ACCEL SEN 1 [V] ××
The accelerator pedal position sensor
signal voltage is displayed.ACCEL SENS2 signal is converted be
ECM internally. Thus, they differs from
ECM terminal voltage signal.
