Does My EGR Valve Need Replaced Or Just Cleaned?

Cleaning it is a temporary fix, if it in fact has chunks blocking it open. if it does, the source of the chunks(the passages in the head/intake/exhaust) need to be cleaned or you will just keep cleaning it over and over and over. Replacing failed GM digital EGRs is a pretty common repair. The computer senses how much flow is present, and how quickly it responds. They go bad, chunks need not be the cause.

1. How to remove EGR Valve on 2004 impala?

Autozone must have diag would this eh? Its an egr code so the egr must be bad lolz. Anyways, if you feel a need to replace it, take the two bolts out and the connector, I doubt that is the problem though

2. what is an EGR valve?

As stated by Loonatic, it is a exhaust gas recirculation valve. It is designed to become effective at cruise or constant speeds above 45 mph. It opens a small hole into the intake manifold allowing inert exhaust gases into the intake. This then lowers the combustion temperature lowering the amount of NOX that your vehicle produces and in return, it increases your gas mileage. A malfunctioning EGR valve will cause you to fail an emissions test and then the cost becomes irrelevant because you will have to pay what it takes to repair the problem. Hope this helps you to understand

3. Where do I find my egr valve on a 97 ford expedition?

If it is stuck you can pull strong vacuum on it to unstick it. There is probably full of carbon behind it in the throttle body, which makes it seem stuck

4. How do you clean an EGR valve?

depends ! is it electric or vacuum controlled ?

5. How essential is an EGR Valve to the operation of a car?

IT ALLOWS THE ENGINE TO BREATH , LIKE UNDER $5 AT A AUTO PARTS STORE

6. Do I even need an EGR valve?

your EGR valve is all part of the omission system. any one item goes array it could cause engine harm not to mention that you may not pass a state inspection

7. Where is EGR valve located on a 1989 chev camaro 350?

i believe it is under the air cleaner on the passenger side of the motor. if you dont see it there then use the emissions, or vaccum diagram label on the underside of the hood

8. EGR Valve code P0403 [check engine light]??????????

did you blow the tube that the EGR valvle is attached to i had a plug about two foot down so i started engine with just the tube and blew it out my friend almost got hit by it . gave him a dusting of carbon all over his face

9. EGR valve sensor "check engine" light, will this pass or fail for a Pennsylvania Inspection?

definitely fail

10. Would fuel additives be enough to fix my EGR valve problem?

no, remove an soak it in solvent....if this does not work you will need to buy a new valve

11. What are the consequences of a blocked EGR valve?

From my experience, you dont even need the EGR valve on your car to run. I ran a 1990 Jeep Wrangler with my EGR valve covered instead of being connected the way it should and it ran fine. I would say just spend your time to clean it. If your experiencing lag, you may want to check your fuel pumps, and possibly your spark plugs

12. service engine light came on in my 99 ford windstar, had the egr valve replaced, service engine light still on

Disconnect the car battery for five minutes. The light should go out. If it trips again, there is another problem. O2 senors cause them to trip quiet often.

13. How do you test EGR valve on 96 nissan pickup 2400 engine?

Nissan 2400 Engine

14. dodge experts and mechanics help?

Evaporative emission system has something to do with the fume of gasoline,when EGR valve has something to do with the recirculate to burn again some of the exhaust gas.They are different system altogether.Small leak could be a leaking valve or solenoid in the evap system,some of which can only be detected with a smoke machine,nothing to do with EGR system

Multi Channel Laser Anti-theft Alarm Circuit
The figure shows the circuit of multi-channel laser anti-theft alarm. VT1, vt2, RL1, RP1, R1, K and vd6 constitute an optical control switch. During the day, the photoresistor RL1 is in a low resistance state under light, VT1 is saturated on, vt2 is off, relay K is not energized, normally open contact J is off, and the alarm circuit does not work; At night, RL1 changes to high resistance state, VT1 is cut off, vt2 is saturated and turned on, K is powered on to make j pull in, the circuit supplies power to the whole machine, the red LED is on, the regulated voltage is 6V, and supplies power to the subsequent circuit after voltage reduction by vd7, vd8 and vd9. Laser rods JB1, RL2, VT3, RP2, R3 and R4 form a laser transmitting and receiving network. When the alarm is in the waiting state, the laser rod emits red laser and irradiates it on the photoresist RL2. RL2 is in a low resistance state, and the base potential of VT3 is very low, which provides trigger current for thyristor vs, vs is turned on, IC2 is powered on, and the horn gives an alarm sound. The alarm can be equipped with up to 10 laser transmitting and receiving networks at the same time. The circuit structure is exactly the same, and C3 is an anti-interference capacitor. An is a reset switch. When the power grid is cut off or the gangster cuts off the power supply, the battery immediately supplies power to the whole machine, ensuring the reliability of the alarm device.Component selection: IC1 is voltage stabilizing integrated circuit 7806, and aluminum heat sink shall be added during use. IC2 is KD-9561 four sound chip, and the circuit is connected to the second sound selection terminal sel2 (fire truck alarm sound). The laser source is a red laser rod with voltage of 4.5V and power
