The Exhaust Gas Recirculation valve does just what the name implies: it diverts some exhau st gases back into the intake system at low engine speeds. This lowers combustion temperature to reduce NOx levels. It also reduces throttle response and bottom-end power.
Disabling the EGR valve is easy. Locate the valve and the EGR vacuum modulator valve (two gold-colored metal stampings, usually at the rear of the engine). The EGR valve has steel lines leading to it from the exhaust manifold. The EGR vacuum modulator has two vacuum lines between it and the intake manifold and a third vacuum (soft) line between the modulator and the EGR valve itself.
EGR Vacuum Modulator
EGR valve (arrow) is shown adjacent tosimilar EGR vacuum modulator valve. EGR valve is connected to exhaust manifold with steel lines. Modulator has vacuum lines only.
Disconnect the vacuum line between the valve and modulator and place any solid object of appropriate size (dowel, etc.) in the line, then reconnect the line. Or you can get a EGR block off plate

SOURCE: Bolt is stripped, very tight and can't remove from egr valve

The only thing that I can think to help you out is to either drill a small hole in the center of the bolt and then try to get a flat head screw driver in to unscrew it.  Or the other option would be to get those special socket sets that are designed to take out stripped bolts.  The set I have is from Sears and I have used it many times so I know they work but I'm sure you can save some money if you go to Home Depot or Lowes.  Good luck!

I have a 2002 Saturn ls1. I put a code reader on it and I need to remove and clean egr valve. How is this done


locate your EGR valve. Saturn EGR valves are usually located near the intake manifold and throttle body. carefully remove vacuum hoses from the valve. then unbolt it. Remove the EGR valve and discard the old gasket. the valve has 3 bolts on it, 2 in front and one in the backside. if you can not let it soak for a few hours, then clean with shop towels and cotton swabs to remove built up carbon deposits. replace EGR valve with a new gasket. Good-day!

What is a egr valve


  1. Install a tachometer on the engine, following the manufacturer's instructions.
  2. Detach the engine wiring harness connector from the Idle Air Control (IAC) solenoid.
  3. Disconnect and plug the vacuum supply hose from the EGR valve.
  4. Start the engine, then apply the parking brake, block the rear wheels and position the transmission in Neutral.
  5. Observe and note the idle speed.
If the engine will not idle with the IAC solenoid disconnected, provide an air bypass to the engine by slightly opening the throttle plate or by creating an intake vacuum leak. Do not allow the idle speed to exceed typical idle rpm.
Using a hand-held vacuum pump, slowly apply 5-10 in. Hg (17-34 kPa) of vacuum to the EGR valve nipple.
  1. If the idle speed drops more than 100 rpm with the vacuum applied and returns to normal after the vacuum is removed, the EGR valve is OK.
  2. If the idle speed does not drop more than 100 rpm with the vacuum applied and return to normal after the vacuum is removed, inspect the EGR valve for a blockage; clean it if a blockage is found. Replace the EGR valve if no blockage is found, or if cleaning the valve does not remedy the malfunction.

Just replaced EGR hose & valve copver gaskets on 2002 Ford Escape 4WD. Did test drive, runs really rough & almost stops & cuts off. Any ideas?


OK, if you replaced the EGR hose, did you go all the way to change the EGR Valve? A stuck open EGR Valve can cause a rough idle and almost make it cut off.
Also, a vacuum leak on the EGR valve can cause a rough idle.

To Remove:
  1. Disconnect the negative battery cable.
  2. Remove and discard the exhaust manifold-to-EGR tube. Use the following as a guide:
  3. Raise and safely support the vehicle

  9. Detach the vacuum line and remove the two retainer bolts.
NOTE: The EGR valve sealing surfaces are soft metals and easily damaged.
To Install:
  1. Installation is a reverse of the removal process. Carefully clean all sealing surfaces and install a new EGR valve gasket.
  2. Install a new EGR valve tube.

Check engine light on when check it insufficent EGR valve


yes the passages can be cleaned. They pass exhaust gas into the intake maniflod for reburning.

It could be the DPFE that controls the EGR too. Diff. Pressure Feedback EGR.

there is also a vacuum regulator valve and a solenoid too.
