When do you use an electronic EGR valve?
Electronic EGR valves are used in vehicles dated 1990 and up. The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum. The procedure to test an electronic EGR is a bit different and requires a multimeter.
Is the exhaust gas recirculation valve an electronic valve?
The exhaust gas recirculation valve within your vehicle is a crucial component in reducing harmful emissions and ensuring your vehicle runs smoothly. Electronic EGR valves are used in vehicles dated 1990 and up. The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum.
Why do I not feel pressure on my EGR valve?
You should feel vacuum or a slight pressure on your finger tip, depending on the particular system type. If you don’t feel a change in vacuum or pressure, likely the problem lies with the circuit that provides vacuum or pressure to the valve. Reconnect the vacuum hose to the valve.
Can a multimeter be used to test EGR?
The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum. The procedure to test an electronic EGR is a bit different and requires a multimeter. If you notice your vehicle running poorly, stalling or having poor gas mileage, you should test the EGR.
What does the EGR valve do on a Honda Civic?
This procedure is applicable to 2.4L 4 cylinder Honda engines, found on the Civic, Accord, CR-V and Element, Acura TSX, CSX, and ILX as well as other Honda models. The EGR valve is responsible for directing some exhaust gases back into the intake manifold to be reburned by the engine.
How can I tell if my EGR valve has failed?
You need to confirm whether the EGR valve has failed or carbon deposits have began upsetting EGR system and engine operation. Look for a round, thick, metal disc about three inches in diameter. In most cases, you’ll find it around the top area and to one side of the engine. You may need to look between and under some components on your vehicle.
What can I use to clean the EGR valve?
There are two 12mm nuts holding the EGR valve onto the intake manifold, and one electrical connector. To get better access, it is recommended to remove the PCV hose, vacuum line and air box tube. Carb or throttle body cleaner and a pick can be used to clean the valve/port.
Why is my exhaust gas recirculation valve not working?
After miles of service, the exhaust gas recirculation (EGR) system — especially the EGR valve — will lead to engine performance problems due to carbon buildup, components mechanical problems, or vacuum hose leaks.
When do I need to test my EGR valve?
The procedure to test an electronic EGR is a bit different and requires a multimeter. If you notice your vehicle running poorly, stalling or having poor gas mileage, you should test the EGR. High volts could mean there is a blockage somewhere within the EGR valve and no voltage could signal a problem with the valve and computer communication.
What does high volts on EGR valve mean?
If you notice your vehicle running poorly, stalling or having poor gas mileage, you should test the EGR. High volts could mean there is a blockage somewhere within the EGR valve and no voltage could signal a problem with the valve and computer communication. Turn the vehicle off and remove the key from the ignition.
The exhaust gas recirculation valve within your vehicle is a crucial component in reducing harmful emissions and ensuring your vehicle runs smoothly. Electronic EGR valves are used in vehicles dated 1990 and up. The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum.
What happens when the EGR valve fails to close?
When this flow pattern fails, you begin to notice a decline in engine performance. For instance, this will happen if the EGR valve fails to close completely as the engine idles, or fails to open when engine speed increases. Unfortunately, problems in the EGR system and valve will happen sooner or later.
