Toyota RAV4. Transmission fluid temperature sensor "a" performance


Monitor description

This dtc indicates that there is a problem with output from the atf temperature sensor and that the sensor itself is defective. The atf temperature sensor converts the atf temperature to an electrical resistance value. Based on the resistance, the ecm determines the atf temperature, detects open or short circuits of the atf temperature circuit, and detects faults in the atf temperature sensor.

Case 1 (2 trip detection logic): first, the ecm checks for the following conditions:

  1. 17 Minutes or more after the engine is started and after 9 km (5.6 Miles) or more of driving, the ect is -15°c (5°f) or more.
  2. After starting the engine and a certain period of time has elapsed, the ect and iat are -10°c (14°f) or more.

If the conditions are met, the ecm then checks if the atf temperature is less than 20°c (68°f). If so, the ecm interprets this as a fault and illuminates the mil.

Case 2 (2 trip detection logic): first, the ecm checks for the following conditions: (a)ect is 60°c (140°f) or more.

(B)after starting the engine and a certain period of time has elapsed, the ect is less than 35°c (95°f).

If the conditions are met, the ecm then checks if the atf temperature is 100°c (212°f) or more. If so, the ecm interprets this as a fault and illuminates the mil.

Inspection procedure

Hint:

Using the intelligent tester's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save time.

Notice:

In the table below, the values listed under "normal condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

  1. Warm up the engine.
  2. Turn the ignition switch off.
  3. Connect the intelligent tester to the can vim. Then connect the can vim to the dlc3.
  4. Turn the ignition switch on and turn the tester on.
  5. Enter the following menus: diagnosis / enhanced obd ii / data list.
  6. Follow the instructions on the tester and read the data list.

Toyota RAV4. Inspection procedure


Hint:

  • When dtc p0712 is output and the tester output is 150°c (302°f) or more, there is a short circuit.
  • When dtc p0713 is output and the tester output is -40°c (-40°f), there is an open circuit.

Measure the resistance between terminal tho1 (tho) and the body ground.

Toyota RAV4. Measure the resistance between terminal tho1 (tho) and the body ground.


Hint:

If a circuit related to the atf temperature sensor becomes open, p0713 is set in approximately 0.5 Seconds.

It is not necessary to inspect the circuit when p0711 is set.

  1. Check other dtc output (in addition to dtc p0711)
  1. Connect the intelligent tester to the can vim. Then connect the can vim to the dlc3.
  2. Turn the ignition switch on and turn the tester on.
  3. Enter the following menus: diagnosis / enhanced obd ii / dtc info / current codes.
  4. Read the dtcs using the tester.

Result

Hint:

If any other codes besides p0711 are output, perform troubleshooting for those dtcs first.



  1. Check transaxle fluid level

Ok: automatic transaxle fluid level is correct.
