The following are the major sensor reference graphs in “DATA MONITOR” mode.
CLSD THL POS, ACCEL SEN 1, THRTL SEN 1
Below is the data for “CLSD THL POS”, “ACCEL SEN 1” and “THRTL SEN 1” when depressing the accelera-
tor pedal with the ignition switch “ON” and with selector lever in “D” position (A/T models) or with shift lever in
“1st” position (M/T models).
The signal of “ACCEL SEN 1” and “THRTL SEN 1” should rise gradually without any intermittent drop or rise
after “CLSD THL POS” is changed from “ON” to “OFF”.

Description
EBS00QVI
The specification (SP) value indicates the tolerance of the value that is displayed in “DATA MONITOR (SPEC)”
mode of CONSULT-II during normal operation of the Engine Control System. When the value in “DATA MONI-
TOR (SPEC)” mode is within the SP value, the Engine Control System is confirmed OK. When the value in
“DATA MONITOR (SPEC)” mode is NOT within the SP value, the Engine Control System may have one or
more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MI.
The SP value will be displayed for the following three items:
●
B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board cor-
rection)
●
A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)
●
MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
PFP:00006
Description
EBS00QVM
Intermittent incidents (I/I) may occur. In many cases, the malfunction resolves itself (the part or circuit function
returns to normal without intervention). It is important to realize that the symptoms described in the customer's
complaint often do not recur on (1st trip) DTC visits. Realize also that the most frequent cause of I/I occur-
rences is poor electrical connections. Because of this, the conditions under which the incident occurred may
not be clear. Therefore, circuit checks made as part of the standard diagnostic procedure may not indicate the
specific malfunctioning area.
Common I/I Report Situations
Diagnostic Procedure
EBS00QVN
1.
INSPECTION START
Erase (1st trip) DTCs. Refer to
EC-582, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMA-
.
>> GO TO 2.
2.
CHECK GROUND TERMINALS
Check ground terminals for corroding or loose connection.
Refer to “HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCEDENT”, GI-21, “Inci-
dent Simulation Tests”.
OK or NG
OK
>> GO TO 3.
NG
>> Repair or replace.
3.
SEARCH FOR ELECTRICAL INCIDENT
Perform “HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT”, GI-21, “Incident
Simulation Tests”.
OK or NG
OK
>> INSPECTION END
NG
>> Repair or replace.
STEP in Work Flow
Situation
II
The CONSULT-II is used. The SELF-DIAG RESULTS screen shows time data other than “0” or “[1t]”.
III
The symptom described by the customer does not recur.
IV
(1st trip) DTC does not appear during the DTC Confirmation Procedure.
VI
The Diagnostic Procedure for PXXXX does not indicate the malfunctioning area.

POWER SUPPLY CIRCUIT FOR ECM
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
