The EGR, or exhaust gas recirculation valve, takes inert exhaust gasses drawn from the exhaust system and reintroduces them into the combustion chamber through the intake manifold. This process lowers the peak combustion temperature and helps combat the formation of Nitrous Oxide (NOx) in the exhaust.

  1. Separate the intake ducts from the air cleaner assembly by loosening the retaining clamps and pulling the ducts away from the housing.
  2. Disconnect the vacuum line from the air cleaner assembly.
  3. Remove the wing nut that secures the air cleaner housing lid to the base.
  4. Remove both the air cleaner hosing lid and base.
  5. Locate the EGR valve. Look at the front of intake manifold. The EGR valve will be bolted to the intake manifold just in front of the carburetor.
I hope help you with this. Good luck.

SOURCE: Pls where is Swirl Control Solenoid Valve located in Infiniti QX4

This link shows the location of the SCV, If your motor is different the location should be similiar. http://img510.imageshack.us/img510/5687/vacuumdiagramuh3.jpg

There's a vaccuum line that runs off the SCV to the SCV check switch.

P0442: Have you inspected the lines, charcoal cannister etc? Make sure the fuel cap is tight. The easiest way to check the system is to have someone perform a smoke test. I had a DTC on my car which indicated a EVAP problem, it turned out to be the Fuel tank evaporator Control Solenoid.

SOURCE: EGR VALVE ON 96 FORD PROBE SE

If it's a 2.0L, 5 speed (1994-7) there are two DPFE solenoids (both w/ 3 vacuum ports) near the oil filter, which control the EGR valve. They are discontinued and impossible to find except on junked cars. (FORD #'s K5T44093-4)
I have to junk my 1996 Probe if I don't find them - Missouri emissions.

Where is egr valve located on 2006 Cadillac DTS


I'm not familiar with your vehicle (I'm in the UK). However, the EGR valve is usually connect to the air intake.

Look for a 'unit' that is connected to the air intake via a tube.

Here's a link done with a general Google search for '2006 Cadillac DTS egr'. Hopefully you will recognise your own egr valve amongst the images:

Where is the purge valve located


I assume you are taking about the evap system purge valve - the purge valve is located behind the EGR valve on the left side of the engine.

I need to know how to change an egr valve on my 2003 mazda protege 5


This link is to a "How To Replace an EGR Valve" video. While he is doing this on a Ford F150 pickup, the tips he gives you should translate over to your Mazda easily, especially as he talks about the stickers under the hood designed to tell you where your EGR valve and solenoid is located. Give it try...I think it will work for you.

CODE 48 (EGR problem)did diagnostic,and all tests fine, but service engine indicator comes back soon after driving car and same code 48 is reactivated.


The tests for code 48 are quite extensive. Most common causes were the EGR solenoid , and vacuum to it. Its control begins in the PCM under the dash, miles of wiring, then the solenoid. The solenoid is located just forward of the EGR VALVE both being on the R/S of the throttle body on top of the engine.
