(to Engine Oil Temperature Sensor)HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
- Disconnect the engine oil temperature sensor connector.
- Turn the power switch on (IG).
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Switch Condition Specified Condition C116-3 (VC) - C116-2 (GND) Power switch on (IG) 4.5 to 5.5 V C116-4 (TOUT) - C116-2 (GND) Power switch on (IG) 0.54 to 4.86 V - Turn the power switch off and wait for at least 30 seconds.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Switch Condition Specified Condition C116-2 (GND) - Body ground Power switch off Below 1 Ω C116-3 (VC) - C116-4 (TOUT) Power switch off 171 to 189 kΩ Result
Proceed to OK NG
Result:
OK
REPLACE OIL PRESSURE AND TEMPERATURE SENSOR. Refer to REMOVAL [07/2019 - ]
Result:
NG
See step 2
- CHECK HARNESS AND CONNECTOR (ENGINE OIL TEMPERATURE SENSOR - ECM)
- Disconnect the engine oil temperature sensor connector.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition C116-2 (GND) - C88-100 (EPEO) Always Below 1 Ω C116-4 (TOUT) - C88-123 (THEO) Always Below 1 Ω C116-4 (TOUT) or C88-123 (THEO) - Other terminals Always 10 kΩ or higher Result
Proceed to OK NG
Result:
OK
REPLACE ECM. Refer to REMOVAL [08/2020 - 08/2021]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
