4.
Select “DATA MONITOR” mode with CONSULT-II.
5.
Make sure that “FUEL T/TMP SE” is more than 0
°C (32°F).
6.
Start engine and wait at least 20 seconds.
7.
If 1st trip DTC is detected, go to
WITH GST
1.
Start engine and warm it up to normal operating temperature.
2.
Check that voltage between ECM terminal 60 (Fuel tank temperature sensor signal) and ground is less
than 4.2V.
3.
Turn ignition switch OFF and wait at least 10 seconds.
4.
Start engine and wait at least 20 seconds.
5.
Select MODE 7 with GST.
If 1st trip DTC is detected, go to

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 the ECM terminals, such as the ground.
Diagnostic Procedure
UBS00DYA
1.
CHECK RUBBER TUBE
1.
Turn ignition switch OFF.
2.
Check rubber tube connected to the sensor for clogging, vent,
kink, disconnection or improper connection.
OK or NG
OK
>> GO TO 2.
NG
>> Reconnect, repair or replace.
2.
RETIGHTEN GROUND SCREWS
1.
Loosen and retighten engine ground screws.
>> GO TO 3.
3.
CHECK CONNECTOR
1.
Disconnect EVAP control system pressure sensor harness connector.
2.
Check sensor harness connector for water.
Water should not exist.
OK or NG
OK
>> GO TO 4.
NG
>> Repair or replace harness connector.

4.
CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR POWER SUPPLY CIRCUIT
1.
Turn ignition switch ON.
2.
Check voltage between terminal 3 and ground with CONSULT-II
or tester.
OK or NG
OK
>> GO TO 6.
NG
>> GO TO 5.
5.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors C1, M67
●
Harness connectors M81, F36
●
Harness for open or short between EVAP control system pressure sensor and ECM
>> Repair harness or connectors.
6.
CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR GROUND CIRCUIT FOR OPEN AND
SHORT
1.
Turn ignition switch OFF.
2.
Check harness continuity between EVAP control system pressure sensor terminal 1 and engine ground.
Refer to Wiring Diagram.
3.
Also check harness for short to power.
OK or NG
OK >> GO
