Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
Check
Yes
No
1
CHECK 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
(B136) No. 27 — Engine ground:
(B136) No. 35 — Engine ground:
Is the resistance more than 1
M
Ω?
Repair the ground
short circuit
between ECM and
oil temperature
sensor connector.
2
CHECK POOR CONTACT.
Check poor contact in oil temperature sensor
connector.
Is there poor contact in oil tem-
perature sensor connector?
Repair the poor
contact.
Replace the oil
temperature sen-
sor. <Ref. to
FU(H6DO)-29, Oil
Temperature Sen-
sor.>

1
CHECK 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.
2
CHECK 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.
3
CHECK 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?
Repair the har-
ness and connec-
tor.
NOTE:
In this case, repair
the following:
• Open circuit of
harness between
ECM and oil tem-
perature sensor
connector
• Poor contact in
oil temperature
sensor connector
• Poor contact in
ECM connector
• Poor contact in
coupling connector

CHECK HARNESS BETWEEN OIL TEMPER-
ATURE SENSOR AND ECM CONNECTOR.
1) Turn the ignition switch to OFF.
2) Measure the resistance of harness
between oil temperature sensor connector and
engine ground.
Connector & terminal
(E75) No. 1 — Engine ground:
Is the resistance less than 5
Ω?
Replace the oil
temperature sen-
sor. <Ref. to
FU(H6DO)-29, Oil
Temperature Sen-
sor.>
Repair the har-
ness and connec-
tor.
NOTE:
In this case, repair
the following:
• Open circuit of
harness between
ECM and oil tem-
perature sensor
connector
• Poor contact in
oil temperature
sensor connector
• Poor contact in
ECM connector
• Poor contact in
