Component Inspection

Check "OIL TEMPERATURE SENSOR"
1. Ignition "OFF".
2. Disconnect the "OIL TEMPERATURE SENSOR" connector.
3. Measure the resistance between "Signal" terminals and "Ground" of the "OIL TEMPERATURE SENSOR".

Specification :Refer to " Reference data"




[Reference data]





4. Is resistance within specifications?





Check PCM
1. Ignition "ON" & Engine "OFF".
2. Connect "OIL TEMPERATURE SENSOR" connector.
3. Install scantool and select a SIMU-SCAN,
4. Simulate voltage (0->5 V) to "OIL TEMPERATURE SENSOR" signal circuit.








Fig 1) INPUT 1.00 V -> 78°C (171°F)
Fig 2) INPUT 2.00 V -> 46°C (111°F)
** The values are subject to change according to vehicle model or conditions.
5. Is FLUID TEMP. SENSOR signal value changed according to simulation voltage?
