WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the evaporator temperature sensor (see EVAPORATOR TEMPERATURE SENSOR REPLACEMENT  ).
  2. Dip the sensor in ice water, and measure the resistance between terminals No. 1 and No. 2.
