download The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. Government regulations require onboard Testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. During self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system. The main purpose of the LDP is to pressurize the fuel system for leak checking. It closes the EVAP system vent to atmospheric pressure so the system can be pressurized for leak Testing. The diaphragm is powered by engine vacuum. It pumps air into the EVAP system to develop a pressure of about 0.25 psi. A reed switch in the LDP allows the PCM to monitor the position of the LDP diaphragm. The PCM uses the reed switch input to monitor how fast the LDP is pumping air into the EVAP system. This allows detection of leaks and blockage.

How do I sing with my diaphragm (not my throat)?
Alot of people tell me that I need to sing with my diaphragm, and not my throat. How do I do this? Also, How can I Expand my vocal chords?

Well I really want to be able to reach high notes and I heard you have to sing from your diaphragm or something. Can you help?

My voice teacher is always telling me to breath from my diaphragm but its always hard for me. She tells me to put my hands on my waist and if I feel my fingers expanding to the front and my thumb expanding to the back then I am breathing properly but when I do that I feel like the air isn’t going to my lungs and like I’m out of breath or like I’m holding my breath. I’m not sure how to explain it. I don’t have the best posture could that be why?

Please teach me on how to use the diaphragm. I don’t know how to do it. Please. Help
