  1. Disconnect the ambient air temperature sensor connector.
  2. Using a J 39200 , measure the resistance across the ambient air temperature sensor terminals at two different temperatures. Refer to Circuit Testing in Wiring Systems.
  3. Compare the readings to the specified measurements. Refer to Outside Air Temperature Sensor Resistance .

Are the readings within specifications?

  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Disconnect the driver information display module connector.
  3. Using the J 35616 , connect a J 39200 digital multimeter (DMM) to driver information display module connector cavity 9 (CKT 817 DK GRN/WHT) and cavity 8 (CKT 451 BLK/WHT). Connect the RED lead to cavity 9. Connect the BLK lead to cavity 8. Refer to Circuit Testing in Wiring Systems.
  4. Set the J 39200 DMM to measure DC volts.
  5. Push the Hz button once on the J 39200 DMM. Hz should be displayed on the right side of the screen.
  6. Start the vehicle.
  7. Depress the brake pedal.
  8. Place the vehicle in a forward gear.
  9. Release the brake.
  10. Accelerate in order to maintain a constant speed of 25 mph. (MPH x 1.111 = Hz)

Does the J 39200 DMM show a value within the specified range?

25-30 Hz

Go to Step 9

Go to Step 8
