DTC P0710/38 OIL TEMPERATURE SENSOR SYSTEM

1. Disconnect connector B of the transmission wire.
2. Check the resistance between the terminals.

   Standard:

   Terminal No. (terminal symbol)	Oil temperature [°C (°F)]	Resistance value [kΩ]
   B3 (ATF+) ↔ B8 (ATF-)	10 (50)	6.445±0.645
   B3 (ATF+) ↔ B8 (ATF-)	110 (230)	0.247±0.016

3. Check the insulation of the terminals.

   Standard:

   Terminal No.(terminal symbol)	Resistance value [kΩ]
   B3 (ATF+) ↔ Body earth	1 MΩ or more

   
   

   To step 3

   Proceed to [2]INSPECT WIRE HARNESS AND CONNECTOR (TRANSMISSION WIRE - TRANSMISSION CONTROL COMPUTER ASSY)

1. Connect connector B of the transmission wire.
2. Disconnect connector A and connector B of the transmission control computer ASSY.
3. Check the resistance between the terminals.

   Standard:

   Terminal No. (terminal symbol)	Oil temperature [°C (°F)]	Resistance value [kΩ]
   B15 (OIL) ↔ A28 (E2)	10 (50)	6.445±0.645
   B15 (OIL) ↔ A28 (E2)	110 (230)	0.247±0.016

   
   

   Repair or replace wire harness and connector.

   Inspect and replace the transmission control computer ASSY.

1. Remove the temperature sensor.
2. Immerse the sender part of the temperature sensor into a vessel filled with original Toyota Auto Fluid Type T-IV.
3. Heat the fluid and check the resistance between the terminals.

   Standard:

   Oil temperature [°C (°F)]	Resistance value [kΩ]
   10 (50)	6.445±0.645
   110 (230)	0.247±0.016

   
   

   

   Take care not to heat the oil excessively, as the oil may catch fire.

   Replace the automatic transmission ASSY.

   Repair or replace the transmission wire.

1. Confirm the DTC P0710/38 is inactive

   • Start the engine and let it idling condition.
   • Verify the DTC P0710/38 is inactive.

   

2. DTC Clear

   • Clear the DTC with Hino DX
   • Confirm the same DTC is not reoccurred

   

P0710/38 is reoccurF Return to first process Other DTC appearF Refer to concerned Trouble shooting
