HVAC Low Pressure Sensor Testing
HVAC Low Pressure Sensor Testing Video describes testing of the HVAC or automotive climate control LOW pressure sensor or switch. The low pressure switch has a direct effect on the compressor magnetic clutch engagement. This component is often connected to the ECM for direct compressor control during WOT. See how it works and tip for diagnostics. ************************************************************************************** Amazon Printed-Books & Kindle: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dstripbooks&field-keywords=mandy+concepcion Google Play Android APPs: https://play.google.com/store/search?q=mandy+concepcion&c=apps Amazon Video DVDs: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dmovies-tv&field-keywords=mandy+concepcion Barnes & Noble Nook: http://www.barnesandnoble.com/s/mandy-concepcion?keyword=mandy+concepcion&store=allproducts Apple iTunes iPad: http://itunes.apple.com/us/artist/mandy-concepcion/id449573393?mt=11

Did you know that a faulty HVAC or air conditioning high pressure sensor can make the engine not start? It so happens that on some vehicles (Cadillacs) the high pressure sensor is connected to the other sensor voltage reference line. So a shorted sensor will render the crank sensor inoperable. Get the scoop here on pressure sensors. They're used in injection systems, transmission, HVAC and many other systems. Presented using advanced software CG animation technology to help you understand.

HVAC High Pressure Sensor
HVAC High Pressure Sensor Describes the operation of the A/C (HVAC) or air conditioning high pressure sensor. This sensor is often the source of a NO-START condition. It sometimes shares the reference voltage with other sensors, such as the MAP, MAF sensor. This means that a short in this circuit will render the engine inoperative. See how it works in this training video. Get the scoop on this often ignored automotive sensor. ************************************************************************************** Amazon Printed-Books & Kindle: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dstripbooks&field-keywords=mandy+concepcion Google Play Android APPs: https://play.google.com/store/search?q=mandy+concepcion&c=apps Amazon Video DVDs: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dmovies-tv&field-keywords=mandy+concepcion Barnes & Noble Nook: http://www.barnesandnoble.com/s/mandy-concepcion?keyword=mandy+concepcion&store=allproducts Apple iTunes iPad: http://itunes.apple.com/us/artist/mandy-concepcion/id449573393?mt=11

Common rail injection system
The injection technology used in the TGL and TGM is the most sophisticated one: a state-of-the-art common rail injection system with vertically positioned 7-jet injector nozzle. The latest generation of EDC7 control units provide the controls of the system. Only this system ensures the best-possible control of the fuel injection process. In each compression stroke, the injection quantity can be divided into pre-injection (1) and main injection (2). In some cases, a post-injection (3) is used. The engines operate with an increased maximum injection pressure of more than 1,800 bar in order to reduce the soot particles inside the engine. The engine runs extremely quietly and noise emissions are low due to the pre-injection (1). The common rail system also supplies considerable advantages in torque, particularly at low speeds. At all engine ratings, the favourable progression of torque across a wide range of engine speeds makes driving economical and requires very few gear shifts.

How To Find and Repair AC Leaks - EricTheCarGuy
Visit me at: http://www.ericthecarguy.com/ How To Recharge an AC System: http://www.youtube.com/watch?v=lglPJuBXVeE Basics of AC: http://www.youtube.com/watch?v=w17DpGCcRj8 AC Performance Test: http://www.youtube.com/watch?v=XU_A4wNuHXI I suppose this has been a long time coming but for me I wanted to make sure that I made a video that would be useful to you as well as emphasized the importance of good practices when working with AC. Keep in mind refrigerant is a CFC meaning that it pretty much kills the ozone layer and if you don't respect that you WILL cause environmental damage even a little adds up so please follow the precautions in this video when working on an AC system. The other thing about AC is that it involves a lot more than just shooting a can of refrigerant into the system when it's not working right there are many systems that come into play that you need to consider such as; the health of the cooling system, cooling fan operation, the mechanical operation of the components of the system, the operation of the HVAC inside the dash, and the electronics so keep in mind if you're having a problem with your AC it could be much more than just a simple leak.
