A 1995 Toyota corolla automatic failed the low speed nox part of the Texas emission test what you can do to past this test Where is the egr valve and how do you clean it?
The EGR system has two main parts: EGR Vacuum Modulator and EGR Valve. The EGR Vacuum Modulator is easy to find at the top-rear of the engine. It is round and has several vacuum hoses attached to it. This part can be removed by twisting/pulling the hoses and sliding it out of it's bracket. There is a filter inside the top cap of the EGR Vacuum Modulator which can be cleaned with soapy water. Dry it thoroughly after cleaning. The EGR Valve, also round, is directly below the Modulator and connected to the modulator via a vacuum hose. It can be removed by removing two 13mm nuts, one vacuum hose and one electrical connector. The electrical connector simply unplugs. NOTE: There is a thin gasket between the valve and the head. Do not lose this. Once you have the EGR Valve removed, detach the tube with the phillips-head screw and then Unscrew the EGR Gas Temp Sensor (the part with the wire). Clean the EGR Valve with engine cleaner or carb cleaner or parts cleaner. Mine was FULL of thick oil/gunk. Clean the gasket, the temp sensor and the mating parts. Clean any gunk out of the hole in the head (a flexible mirror will help you see what's in there). Re-assemble everything. Don't forget to put the filter back into the Modulator. NOTE: The Modulator filter goes in with the smooth side down toward the ground. Reset your Check Engine fuse (15 Amp - located inside the under-hood fuse box).
