Blocking off an EGR valve can make the car run rough. The fuel mileage can suffer as well, since the car is designed to have the EGR valve operable.
The EGR system recirculates dirty unburnt emission gases back into your engine through the intake manifold which decreases performance, but improves gas mileage. You can bypass the EGR valve. Just buy a block off plate from you local speed shop. However, the EGR valve is there to cool the combustion chamber so without it, you will hear a lot of pinging until the motor melts.
its the hose coming off of the valve cover that's the egr valve
The egr valve should be coming off of the exhaust manifold.
Late 98 they stopped using EGR valves on the S-10. They installed a block off plate in its place.
good luck i think it is behind the block on the left u have to take off your whole intake to get to it
EGR is the acronym for exhaust gas recirculation valve. This valve controls the pollutant level given off by the vehicle.
You cannot simply turn an EGR valve off. You can clean it, replace it, or remove it, but you cannot turn it off.
It is required by law in some places and if you block it off the check engine light will occasionally come on.
It's easy to block off the EGR valve. Just use the gasket on it as a template and cut a piece of thin metal (aluminum or sheet) that same size. Drill the appropriate holes in it to match the gasket for the bolts and place it in between the valve and the EGR tube. Of course this tells the ECM that there is INSUFFICIENT EGR flow and the MIL light may come on. If the sensor isn't disconnected at this point the computer will direct the EGR valve to be opened more and more. More than one trouble code could be set but they would ALL be emissions related. Driveability won't be adversely affected on the 2.3L. The only way to "block" off the EGR sensor itself is to unplug the electrical connector...again, driveabiliy should not suffer but the ECM is going to find the changes regardless. It is quite difficult to fool it when it comes to emissions.
The EGR valve and the EGR sensor work together. The EGR gas temperature sensor is mounted near the EGR valve. The sensor detects the temperature of the exhaust as it moves through the valve. The information is sent to the ECM and in turn the EGR on/off time is regulated precisely and more efficiently. Any malfunction with the EGR gas temperature sensor will set off a code 35 ( Info taken from HAYNES MANUAL)
If you mean the EGR (exhaust Gas Reclaimer), no.
The EGR Valve on a 2006 Corolla is located on the driver's side of the motor at the very top of the valve cover. Look for a disk shaped valve that kind of looks like a flying saucer. It has two small hoses coming off of it that are connected to the EGR Valve Modulator.
