Toyota RAV4 Service Manual: Solar sensor circuit (driver side)

Toyota RAV4. Solar sensor circuit (driver side)


Description

The solar sensor, which is installed on the upper side of the instrument panel, detects sunlight and controls the air conditioning auto mode. The output voltage from the solar sensor varies in accordance with the amount of sunlight. When the sunlight increases, the output voltage increases. As the sunlight decreases, the output voltage decreases.

The air conditioning amplifier detects changes in the output voltage from the solar sensor.

  1. Inspect solar sensor

Toyota RAV4. Inspect solar sensor


  1. Remove the solar sensor.
  2. Measure the resistance of the sensor.
  3. Connect the ohmmeter's positive (+) lead to terminal 1 and the negative (-) lead to terminal 3 of the solar sensor.

Standard resistance


Notice:

The connection procedure for using a digital tester such as an electrical tester is shown above. When using an analog tester, connect the positive (+) lead to terminal 3 and the negative (-) lead to terminal 1 of the solar sensor.

Hint:



  1. Check wire harness (solar sensor - air conditioning amplifier)
