This can include frequent fluctuations in temperatures or difficulty maintaining a consistent temperature. Many sun load sensors can be tested with an ohmmeter and a bright light, watching for fluctuations in the sensor's resistance. Remove the sun load sensor from the upper trim panel. The first step is to clean any connectors and contacts that may be present as dirt or corrosion can cause false readings. Sunload sensors are usually located at the top of the dash and are often mounted on a removable plate, speaker grill, or defroster vent. The (EATC) electronic automatic temperature control system uses the sun load and in-cabin temperature sensor inputs to adjust blower speed and improve passenger comfort. If the ambient temperature sensor fails or is sending out an inconsistent signal, then the AC system may have trouble maintaining cool and comfortable cabin temperatures. Testing a sun load sensor is relatively simple but requires special tools such as a multimeter or scanner for accurate readings. If any dirt or debris is visible in this area, it should be removed before proceeding further with testing or replacement procedures. Honda Accord V6-3.5L - Heating AC - Sacramento, California.

Resistance in the sensor increases as sun load increases. Excessive fan noise: A bad sun load sensor may also cause an increase in fan noise as the climate control system attempts to adjust temperatures without proper input from the sensor. Symptoms of a Bad or Failing Ambient Temperature Sensor (Switch) There are 2 fuel pumps in the tank, each with a large seal, that must be installed perfectly to avoid fuel/fume leakage. 2. The life and/or performance of gas detection sensors can be affected by various factors, including: Temperature Humidity Interfering gases Physical factors, e.g. Your Your cars engine needs a considerable number of sensors in order to operate correctly.

Q: What are the symptoms of a bad sun load sensor? Install the instrument panel upper trim panel. Usually a default negative temperature. Most people are familiar with the concept of a sun sensor its a device that measures the amount of sunlight that hits it. The AC pressure switch protects the AC system from pressure that's too high or low. These sensors can be very useful in helping to keep your car at a comfortable temperature, no matter what the weather is like outside. The sunlight sensor for the car climate control system is a photosensor that detects the level of daylight and adjusts the temperature in the vehicle accordingly.
