If you want to do further testing, connect a vacuum pump (available at auto parts stores or bring your valve to a local mechanic) to the diaphragm housing and apply a vacuum

Exhaust gas recirculation is normally only permitted at hard acceleration or when the vehicle is already cruising at 30 mph or above and the vehicle is accelerated. This article will help you to diagnose all of the above DTCs, since it covers how to test the EGR Solenoid (which I call the Pintle Motor), the EGR Pintle Position Sensor and Carbon Blockages (the EGR Solenoid and Pintle Position Sensor all are inside and part of the EGR Valve itself)
How do I know if a valve gasket is bad?

The first sign is that your temperature gauge shows the engine is running hot, sometimes the needle will continually swing from a hotter temp to back to normal

Exhaust Gas Recirculation Valve (EGR) During the Smog Check: During the Basic Smog Test the smog machine is not designed to actually look at the EGR System through the engine's exhaust. Now as for the Enhanced Smog Test, the smog test machine reads NOx emissions through the tailpipe which eliminates the need for the smog check technician to inspect the EGR system physically
How do you determine if the foot valve is bad in a deep well pump or if there is a problem with the bladder tank

Most likely your valve has failed.It did this very often until we had the entire mechanism in the well replaced and installed a submersible pump.No problems since and the submersible pump is hardly audible compared to the old pump motor which was mouted near the well head in the basement.Good luck. This could indicate a failed backflow pre How much air should be put in a deep well bladder tank? The air charge in a bladder tank should be 2 PSI below the pressure switch ON setting

This focuses specifically on the valve body replacement of the Toyota A750E or A750F model transmission, and can also be applied to the AB60E or AB60F transmission, which can be found in vehicles like the Tundra, FJ Cruiser, 4Runner, Sequoia, and more...

On modern cars, determining when to open and close the EGR valve is the responsibility of the engine computer.How can you tell if the valve needs to be cleaned or replaced? Most modern car computers monitor many systems and the "check engine" light will illuminate to notify the driver if there is a problem. If the EGR valve is malfunctioning, an EGR error code will be generated by the computer.If the "check engine" light does not illuminate or your car does not have a service light, you can still use your mechanical ability to determine if the EGR valve is working

The car runs like the day I bought it back in 2004! I'm keeping it because I love the way it drives and all the transmission codes got erased because now it is accelerating properly and shifts when it reaches the correct mph speed. Some mechanical versions will not open until there is sufficient back pressure, ensuring that the valve will not be open when the engine is idle or warming up and needs a higher concentration of oxygen for combustion

Then unplug the electrical connector, if your vehicle is electronically controlled; otherwise, unbolt the mounting bolts that hold the valve to the intake manifold. The vacuum pressure should hold steady somewhere between 15 and 22 PSI for many engines; however, the most important thing is that the pressure stays constant
