SIG-
NALSDescription Remarks
ENG SPEED [rpm]××

Indicates the engine speed computed from the
signals of the crankshaft position sensor
(POS) and camshaft position sensor (PHASE).

Accuracy becomes poor if engine
speed drops below the idle rpm.

If the signal is interrupted while
the engine is running, an abnor-
mal 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 injec-
tion pulse width programmed into ECM, prior
to any learned on board correction.
A/F ALPHA-B1 [%]×

The mean value of the air-fuel ratio feedback
correction factor per cycle is indicated.

When the engine is stopped, a
certain value is indicated.

This data also includes the data
for the air-fuel ratio learning con-
trol.
COOLAN TEMP/S
[°C] or [°F]××

The engine coolant temperature (determined
by the signal voltage of the engine coolant
temperature sensor) is displayed.

When the engine coolant temper-
ature sensor is open or short-cir-
cuited, ECM enters fail-safe
mode. The engine coolant tem-
perature determined by the ECM
is displayed.
HO2S1 (B1) [V]××

The signal voltage of the heated oxygen sen-
sor 1 is displayed.
HO2S2 (B1) [V]×

The signal voltage of the heated oxygen sen-
sor 2 is displayed.
HO2S1 MNTR (B1)
[RICH/LEAN]××

Display of heated oxygen sensor 1 signal dur-
ing air-fuel ratio feedback control:
RICH: means the mixture became “rich”, and
control is being affected toward a leaner mix-
ture.
LEAN: means the mixture became “lean”, and
control is being affected toward a rich mixture.
After turning ON the ignition
switch, “RICH” is displayed until
air-fuel mixture ratio feedback
control begins.

When the air-fuel ratio feedback
is clamped, the value just before
the clamping is displayed contin-
uously.
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.
VHCL SPEED SE
[km/h] or [mph]××

The vehicle speed computed from the vehicle
speed signal 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 SEN 2 signal is con-
verted by ECM internally. Thus, it
differs from ECM terminal voltage
signal. ACCEL SEN 2 [V]×
THRTL SEN 1 [V]××

The throttle position sensor signal voltage is
displayed.

THRTL SEN 2 signal is con-
verted by ECM internally. Thus, it
differs from ECM terminal voltage
signal. THRTL SEN 2 [V]×

CAUTION:

The quick connector can be removed when the tabs are
completely depressed. Do not twist it more than neces-
sary.

Do not use any tools to disconnect quick connector.

Keep the resin tube away from heat. Be especially careful
when welding near the tube.

Prevent acid liquid such as battery electrolyte etc. from
getting on resin tube.

Do not bend or twist the tube during installation and
removal.

Do not remove the remaining retainer on hard tube (or
equivalent) except when resin tube or retainer is
replaced.

When resin tube or fuel level sensor unit is replaced, also
replace retainer with a new one.

To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
8. Using a fuel tank lock ring wrench (commercial service tool),
remove the lock ring.
9. Remove main fuel level sensor unit (Left hand) and sub fuel level sensor unit (Right hand).
CAUTION:

Do not bend the float arm during removal.

Avoid impacts such as falling when handling components.
Left hand (main fuel level sensor unit):

If necessary, remove the chamber from the bottom of the fuel tank.

Remove the chamber by sliding toward the rear of the vehicle.Retainer color : Green (Fuel feed tube)

BAULK RING CLEARANCE
Triple-cone synchronizer (1st and 2nd)

Check the clearance between outer baulk ring, synchronizer
cone and inner baulk ring as follows.
CAUTION:
The clearances “A”, “B” and “C” are controlled with outer
baulk ring, synchronizer cone and inner baulk ring as a set.
Replace them as a set if the clearances are outside the limit
value.
1. Measure the clearance “A” at 2 points or more diagonally oppo-
site using a feeler gauge when pressing baulk ring toward clutch
gear taper cone. And then calculate mean value.
2. Measure the clearance “B” at 2 points or more diagonally oppo-
site using a feeler gauge. And then calculate mean value.
