Toyota RAV4. Engine coolant temperature circuit range / performance problem


Monitor description

Engine coolant temperature (ect) sensor cold start monitor

When a cold engine start is performed and then the engine is warmed up, if the ect sensor value does not change, it is determined that a malfunction has occurred. If this is detected in 2 consecutive driving cycles, the mil is illuminated and a dtc is set.

Ect sensor soak monitor

After a warmed up engine is started, if the ect sensor value does not change when the engine is stopped and then the next cold engine start is performed, it is determined that a malfunction has occurred. If this is detected in 2 consecutive driving cycles, the mil is illuminated and a dtc is set.

Inspection procedure

Hint:

  1. Check any other dtcs output (in addition to dtc p0116)

  1. Connect the intelligent tester to the dlc3.
  2. Turn the ignition switch on.
  3. Turn the tester on.
  4. Select the following menu items: diagnosis / enhanced ii / dtc info / current codes.
  5. Read the dtc.

Toyota RAV4. Check any other dtcs output (in addition to dtc p0116)


  1. Inspect thermostat

  1. Remove the thermostat (see page co-15).
  2. Measure the valve opening temperature of the thermostat.

Standard value: 80°c to 84°c (176°f to 183°f)

Hint:

In addition to the above check, confirm that the valve is completely closed when the temperature is below the standard.

  1. Reinstall the thermostat (see page co-15).
