A sunlight sensor is a device that measures the amount of sunlight that hits a given area. This device measures the amount of sunlight that hits the cars windshield and sends a signal to the cars computer to adjust the interior temperature accordingly. The most common symptoms of a bad sun load sensor include: 1. The AC pressure switch protects the AC system from pressure that's too high or low. Check for manufacturer's specifications before testing. If your sun load sensor shorts out, it can cause all sorts of problems with your cars climate control system. In this blog post, well take a look at what can cause a sun load sensor to short circuit, and how you can fix it. If the sun load sensor fails, a fault code sets, and the program enters a default value and tries to achieve the desired temperature setting.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,100],'freeasestudyguides_com-medrectangle-4','ezslot_0',116,'0','0'])};__ez_fad_position('div-gpt-ad-freeasestudyguides_com-medrectangle-4-0'); Sun Load Sensor Test: It's on the dash usually close to the headlight sensor. But what does a climate control sun sensor do? If the controller "thinks" the outside temp is below 28, and you want to defog the windshield. Line: ACD. Install the instrument panel upper trim panel. I haven't looked to see if it's got one, but I'd be surprised if it doesn't. Flat rate pricing based on labor time and parts, Trusted mechanics, rated by thousands of happy car owners, Hand-picked, community-rated professionals, Over 25,000 topics, from beginner tips to technical guides, Check cars for recalls, common issues & maintenance costs, Optimize fleet uptime and compliance via mobile vehicle repairs, Partner with us to simplify and scale fleet maintenance. View voltage readings in a capable scan tool datastream. The ambient temperature sensor plays an important role in the overall operation of the AC system. A faulty MAP sensor can cause a variety , Manifold Absolute Pressure Sensor (MAP); All You Need To Know Read More , Transmission Speed Sensor (TSS): Symptoms, Replacement, and Maintenance, Crankshaft Position Sensor (CKP); All You Need To Know, All You Need To Know About The Camshaft Position Sensor (CMP). The former measures sunlight intensity by detecting changes in resistance levels while PSDs measure light intensity by detecting changes in capacitance. Air conditioning odor: If the sun load sensor is malfunctioning, it can cause a buildup of condensation in some parts of the climate control system, which can lead to an unpleasant odor coming from the air conditioning vents when it is running. Installation. When the ambient temperature sensor fails, the system does not have a reference point from which to base its automatic calculations and the setting will not work. A sun load sensor is a device that measures the amount of sunlight falling on a surface. This includes checking for signs of physical damage or corrosion around wiring connectors and ensuring that all fluid levels are properly maintained throughout its service life. Required fields are marked *. I would recommend him to anyone with a car issue, Hummer H2 V8-6.0L - Heating AC - Brooklyn, New York. To test a sun load sensor with an lux meter, first take readings in different areas of full sunshine and shade. This can help prevent accidents by making sure drivers have their lights on when they need them. An example of data being processed may be a unique identifier stored in a cookie. There are 2 fuel pumps in the tank, each with a large seal, that must be installed perfectly to avoid fuel/fume leakage. The fan speed doesn't seem to be working correctly - it may blow at full blast even when the temperature is only slightly warm, or . Some manufacturers use a photodiode. Written by admin on February 26, 2023. Thermistor. It can be used to measure the intensity of sunlight, as well as the direction and angle of the sun. 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. h) or less Cause: Sunload sensor A/C auto amp. Your email address will not be published. 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. 4. When the ambient temperature sensor fails, there will usually be a few symptoms that may alert the driver that a problem with the sensor has occurred and it should be inspected or replaced if needed. The oil that resides inside of a compressor can get very cold during the winter months. The EATC compares these values and makes output decisions based on the difference between these air temperatures.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'freeasestudyguides_com-box-4','ezslot_1',124,'0','0'])};__ez_fad_position('div-gpt-ad-freeasestudyguides_com-box-4-0'); This sensor can be tested for resistance with an ohmmeter. This is not an uncommon problem. The B2631 is a fairly straight forward code pointing to a problem with the Sunload Sensor. Connect the electrical connector. Both types have their advantages and disadvantages depending on the specific application but both are effective at measuring sunlight intensity for automotive applications. Then gradually move the other end of the element until you notice any change in voltage or resistance level on your multimeter screen; this will indicate where maximum light exposure has been detected.
