- Q: anyone know where this switch or whatever you want to call it is located. the car was in accident. so it wont start but cranks. so i wanted to know where the shut off valve is located for the fuel. thanks.
- 2007 does not have a shut off valve. Sounds as if some one has used a non programed key Nissan Imobilizer has detected the aftermarket non programed or key with chip embedded in the key has failed. After 4 attempts the car turns on lock mode and it is tow truck time. Gather up all the keys you have they all have to be reprogramed. And it is a good time to have two complete sets of keys and remotes money allowing of course. Only computerized lock smiths and Nissan dealerships can introduce keys. Is there a red light that looks like a car with a key lighting up when you attempt to start the car?
- Q: Is there a way to test the EGR valve to see if its still good ? and working right .
- Yes there is. Disconnect the rubber hose on top of the EGR valve. Connect a hand-held vacuum pump to this fitting. Start the engine. Slowly apply vacuum to the fitting on the valve. While applying vacuum with the engine running at idle speed, the idle speed should drop or the engine may even stall. In that case the valve is working. If the engine speed doesn't change, the EGR valve may be defective, or EGR tube may be plugged with carbon, or the passages in the intake and exhaust manifolds may be plugged with carbon. In this case remove the EGR valve from the engine. Again apply vacuum to the EGR valve and observe the stem on the EGR valve. If the stem is moving, it can be assumed that the EGR valve is ok. In that case clean the EGR tube and the intake and exhaust manifolds passages Hope this will help you.
- Q: Hi,I have a 2002 Honda Accord with 115k miles which recently gave a ECL. The Honda dealer identified this a P1457 and says that the EVAP bypass solenoid valve needs to be replaced1) is this referring to this valve?
- If they are saying your ECM needs to be replaced, they're probably pulling your leg. What do they mean a 50/50 chance it needs to be replaced? That's a load of BS. Either it needs to be replaced or it doesn't. Very easy to tell. Simply put the key in your ignition and turn to the ON position (do NOT start the car yet). This should flash the lights on your dash. This would include the oil light indicator, check engine light, etc.. they should come on, then go off after you start the vehicle. If these lights flash, then go off after starting your vehicle, your ECM is fine. Also if the ECM is reporting a check engine light, chances are it's working properly. There is a VERY VERY slim chance it is reporting the wrong code, in which case the ECM could very well be bad, but this is very unlikely. If the solenoid is replaced and the issue persists, it is probably another problem that has triggered the P1457 code. They would need to check the train of what could be communicating with the solenoid in case another component has failed. Unfortunately I'm not sure about the other part of your question but just wanted to give you a heads up about the ECM.
- Q: I have a 2006 saturn vue that has a valve tap in the engine. The car has about 100k miles on it now. I'm the original owner of the car, and I've had the problem with the valve tap since about 50k miles, and even when taking it to saturn dealerships, I was told it was nothing and the car was fine. Now that I know what it is (I took it to another mechanic that was a friend who went over it with a 'fine tooth comb') I ahve done research and know what can go wrong a little too late :(So my question: My car only makes the tapping sound for about 5 or so minutes when i turn the car on, then it goes away and you can't hear it anymore, is this usual for a valve tap?
- Keep eye on oil level and keep on driveing.
- Q: the air valve, how does it propel a paintball in a blowback operated paintball gun how does the size/shape/?? of the valve impact how fast the paintball shoots?
- The majority of blowback paintball guns use a pin valve, which is opened when struck by the hammer. The hammer is held in the back position, with the spring compressed, by a sear. When the trigger is pulled, the hammer is propelled forward by the spring, into the valve. These sorts of markers generally use a “stacked tube” design, in which the valve and hammer is contained in the lower tube, while the bolt, which is connected to the hammer, is in the upper tube. The gas released by the valve is then simultaneously channeled up to the bolt to fire the paintball, and back to push the hammer back into the ****** position (hence the name “blowback”). Poppet valves are usually easy to replace and require little, if any, maintenance. The downside to this design, however, is its high operating pressure, which leads to a larger recoil and arguably less accuracy. The valve is usually designed to accommodate a specific operating pressure. Low pressure valves provide quieter operation and increased gas efficiency when tuned properly. However, excessively low pressure can decrease gas efficiency as dramatically as excessively high pressure. The volume of gas released by the valve directly affects the paintball's velocity. The velocity adjuster alters the pretension on the hammer spring which controls how long the pin valve is held open for, or more correctly how much gas must be released to push it back into the ****** position. EDIT - Sorry but wouldn't even know where to start on designing a valve.
- Q: I own a 2wheel drive 2003 Hyundai Santa Fe 4cly. The engine light was on the code P0401 came up which is the EGR valve. I had it changed out the engine light came back on after I had made it almost home. I took it to auto zone same code came up that made me take to the shop for repair in the 1st place. Ugh. Please help! What's the problem???
- My vehicle is throwing a P0401 code. I was going to replace it, but instead I am going to clean it and replace it. I know the mechanic will want to replace it and charge me well over $100 (I'm seeing the part go for around $52-$55). THe car was recently serviced with the valve cover gasket replaced.
- Q: primary function of a valve position?
- Are you asking about a valve positioner? If so, then a positioner is a device that measures the amount a valve is open or closed and then adjusts the motive force to be sure the valve is in the position the controller calls for. These are typically use in cases of very high differential pressure or where the valve actuator may be under sized or marginal.
- Q: My mum (73, non-smoker, not overweight) has been diagnosed with 2nd degree aortic valve stenosis 5 years ago. Now deteriorating. Her cardiologist sees her every 6 months and strongly recommends surgery. She is too scared as dad died during a coronary bypass op. Any tips how to gently make her feel better about the op? She heard on the radio that some valve replacements can be done via catheter, not necessitating open heart surgery and heart-lung-bypass. Is that true for aortic valves and is it likely to become mainstream soon? She lives in Germany, so I guess good centres would be Munich, Wuerzburg and Heidelberg. Any views very appreciated!
- Unlike the mitral valve which can often be repaired, the aortic valve usually requires replacement. Once the decision is made to proceed with surgery, choices regarding the type of artificial valve (prosthesis) used should be considered. In broad terms there are two types of artificial valves or prostheses: mechanical valves and biological valves. A number of excellent mechanical replacement valves or prostheses are available today. Most surgeons have a particular preference for one valve over another related to technical factors (how they are sewn into place), however from the patient's point of view there is little if any difference between valves. The principle advantage of mechanical valves is their excellent durability. From a practical standpoint, they do not wear out. The principle disadvantage is that there is a tendency for blood to clot on all mechanical valves. Therefore patients with artificial valves must take anticoagulants or blood thinners for the rest of their life. There is also a small but definite risk of blood clots causing stroke. The decision on the type of valve used should be made in conjunction with your cardiothoracic surgeon and your cardiologist. Ultimately the choice will depend on a patient's preferences, lifestyle, and individual risks as determined by age and other medical conditions. I advice you to consult surgeryplanet, which is a global healthcare facilitator. They can give details about this surgery and the good centers for the surgery.
- Q: i have a 1987 nissan 300zx and i can get the car to start unless its 40 degrees and when it does it idles hard. is this idle control valve or a fast idle valve??
- Could be.. Also could be dirty. Easy fix, remove the valve and spray carb cleaner in the hole.. Using a small brush, clean the bore that the valve rides up and down in. Also, inspect the valve while it is off the manifold. Harder fix: After cleaning the bore, replace valve with brand new one. Your car will have to relearn the idle after starting with the new valve or after you put the old one back in.. Start car, but do not put it in drive or give it any throttle until the computer has finished making adjustments. - Dave. (Long Island, NY)
- Q: When I put my check valve on my air line the air doesn't come through the air stone but when I take off the check valve it works. Also I switched the sides of the check valve and it didn't work. Click the link this is the air pump.
- Or if you can, go to petsmart and get one there. Petco tends to sell sub-par items and livestock. If you have a tank that is bigger than your air pump was intended, then you will have problems. Say you bought a 10 gallon air pump for your 20 gallon tank. The strength of the pump is only able to push air down to counteract the average depth of a 10 gallon tank, against the pressure of only that much water. However if it were in a 20 gallon, it may not be able to counteract the water and the check valve (which shouldn't be causing much of a problem anyways). Make your line shorter and see if that helps. You don't need tons of extra airline tubing coiled around. Cut it down to the length you need, and try again. Remember, check valve should be OUTSIDE of the water, in the direction indicated on the valve (as to which side is in, which side is out), and it should be closer towards the pump itself. The check valve just prevents any water from dripping back into the pump.
