What is the purpose of this part? I have a problem with my Hyundai Accent Model GLS 2013 Vin number KMHCT41CBDU419611 When I put the gear in reverse the Car nocks (Shakes) heavily . I have a second problem it has no overdrive. the car has no power at the beginning when in high speed it runs ok. What are the most common problem or what parts do I need to resolve this two problems. I changed the transmission filter already The computer said that I have to change the two Solenoid the left and the right in the Transmission. What about the Fuel Injection Pressure regulator and the sensor does it have a sensor just like Elantra? And what about the fuel filter? Thank you so much, just give me the parts I need and I will order Them.

Hi! Thank you for your question. Faced with such problems, you should take your vehicle to an auto repair body shop to precisely diagnose the problem? Otherwise, you can replace the part that works properly, and this won’t solve your problem.

Hi! A shutdown valve (also referred to as SDV or emergency shutdown valve, ESV, ESD, or ESDV; or safety shut-off valve) is an actuated valve designed to stop the flow of a hazardous fluid upon the detection of a dangerous event. This provides protection against possible harm to people, equipment or the environment. Shutdown valves form part of a safety instrumented system. The process of providing automated safety protection upon the detection of a hazardous event is called functional safety.
