ENGINE (DIAGNOSTICS)
Step Check Yes No
1CHECK HARNESS BETWEEN OIL TEMPER-
ATURE SENSOR AND ECM CONNECTOR.
1) Disconnect the ECM connector and oil tem-
perature sensor connector.
2) Measure the resistance of harness
between oil temperature sensor connector and
engine ground.
Connector & terminal
(B134) No. 23 — Engine ground:
(B134) No. 29 — Engine ground:
Is the resistance more than 1
MΩ?
Go to step 2.Repair the ground
short circuit
between ECM and
oil temperature
sensor connector.
2CHECK POOR CONTACT.
Check poor contact of oil temperature sensor
connector.
Is there poor contact in oil tem-
perature sensor connector?
Repair the poor
contact.
Replace the oil
temperature sen-
sor. FU(H6DO)-27, Oil

Step Check Yes No
1CHECK HARNESS BETWEEN OIL TEMPER-
ATURE SENSOR AND ECM CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from oil tempera-
ture sensor.
3) Measure the voltage between oil tempera-
ture sensor connector and engine ground.
Connector & terminal
(E75) No. 2 (+) — Engine ground (–):
Is the voltage more than 10 V? Repair the battery
short circuit of har-
ness between
ECM and oil tem-
perature sensor
connector.
Go to step 2.
2CHECK HARNESS BETWEEN OIL TEMPER-
ATURE SENSOR AND ECM CONNECTOR.
1) Turn the ignition switch to ON.
2) Measure the voltage between oil tempera-
ture sensor connector and engine ground.
Connector & terminal
(E75) No. 2 (+) — Engine ground (–):
Is the voltage more than 10 V? Repair the battery
short circuit of har-
ness between
ECM and oil tem-
perature sensor
connector.
Go to step 3.
3CHECK HARNESS BETWEEN OIL TEMPER-
ATURE SENSOR AND ECM CONNECTOR.
Measure the voltage between oil temperature
sensor connector and engine ground.
Connector & terminal
(E75) No. 2 (+) — Engine ground (–):
Is the voltage more than 4 V? Go to step 4.Repair the har-
ness and connec-
tor.
NOTE:
In this case, repair
the following item:
•Open circuit
of harness be-
tween ECM and
oil temperature
sensor connec-
tor
•Poor contact
of oil tempera-
ture sensor con-
nector
•Poor contact
in ECM connec-
tor
•Poor contact
of coupling con-
nector
