Description

Remarks

ENG SPEED

rpm

• Indicates the engine speed computed from the 

signal 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 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.

• When engine is running specification 

range is indicated in “SPEC”.

B/FUEL SCHDL

msec

• “Base fuel schedule” indicates the fuel injection 

pulse width programmed into ECM, prior to any 
learned on board correction.

• When engine is running specification 

range is indicated in “SPEC”.

A/F ALPHA-B1

%

• The mean value of the air-fuel ratio feedback cor-

rection factor per cycle is indicated.

• When the engine is stopped, a certain 

value is indicated.

• When engine is running specification 

range is indicated in “SPEC”.

• This data also includes the data for 

the air-fuel ratio learning control.

COOLAN TEMP/S

°

C or 

°

F

• The engine coolant temperature (determined by 

the signal voltage of the engine coolant tempera-
ture sensor) is displayed.

• When the engine coolant temperature 

sensor is open or short-circuited, 
ECM enters fail-safe mode. The en-
gine coolant temperature determined 
by the ECM is displayed.

HO2S1 (B1)

V

• The signal of the heated oxygen sensor 1 is dis-

played.

HO2S2 (B1)

V

• The signal voltage of the heated oxygen sensor 2 

is displayed.

HO2S1 MNTR(B1)

RICH/LEAN

• Display of heated oxygen sensor 1 signal during 

air-fuel ratio feedback control:
RICH: means the mixture became 

″

rich

″

, and 

control is being affected toward a leaner mixture.
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 mix-

ture ratio feedback control begins.

V

• The throttle position sensor signal voltage is dis-

played.

sor) is indicated.

• Indicates start signal status [ON/OFF] computed 

by the ECM according to the signals of engine

played regardless of the starter sig-
nal.

CLSD THL POS

ON/OFF

• Indicates idle position [ON/OFF] computed by
