What are 3 sources that can cause light emissions?
Three sources that can cause light emissions include the sun, which produces light through nuclear fusion, incandescent bulbs that emit light when electricity heats a filament, and fluorescent lights that generate light through the excitation of gas molecules. Other examples include LEDs, which emit light when electrons recombine with holes in a semiconductor, and chemical reactions, such as those seen in fireflies or glow sticks, which produce light through bioluminescence or chemiluminescence.
your vacuum switch is located on the intake manifold to the rear passenger side, it might be stuck open therefor putting out high voltage readings, that's how your computer fugures out if it's open or closed.
AnswerYou might try checking out your emission's systems (misspelled) because it might have something to do with that. AnswerCheck if you got hose off at air cleaner!:) Good Luck!Replace your gas cap! Yes, it might be that simple.
Can anyone tell you what the fix is for trouble code P0440?
What you has is a gas vapor leak in the system, first try tightening or replace the gas cap.
your plenium chamber is made of a plastic material. In one section of it hot gases pass thru it. It now has a hole in it, alowing antifreeze to leak into the intake manifold. Pull your spark plugs and you will be able to confirm what I said was right.

Where is the fuse for the secondary air injection system on a 1997 VW Jetta GL?
Directly behind the driver's side headlight there is a relay that is clearly marked "111". Below the relay is a small, clear, plastic door that flips up. Under that door are two wires screwed to a junction, and connecting the two wires together is a crude fuse. That's it.
Would motor mounts on a dodge neon 2005 cause the engine light to come on?
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
How do you reset the check engine light on a 1997 Dodge ram?
the check engine light is on because there is an existing code in the computer. to reset it you need a code reader... plug the code reader into the port under the drivers side dash and turn the key on...don't crank the vehicle just turn on the key and when the code reader reads the code just erase all the existing codes and the check engine light will go off unless there is still an existing problem with the vehicle and then it will put another code on the computer causing the check engine light to come back on.
Code readers are some what exspensive,go to local autoparts store and they will scan the codes and reset them for you for free..plus they will be able to tell you exactly what is causing the fault.

How do you reset the service engine light on a 2003 Infinity I35?
1. Sit in the driver's seat and turn the ignition switch ON, but don't start it.
2. Wait exactly 3 seconds.
3. Quickly push the accelerator down fully (and fully release it) 5 times in less than 5 seconds.
4. With your foot away from the accelerator, wait exactly 7 seconds.
5. Push and hold the accelerator for 10 seconds until the CEL/SES light starts to flash. Wait a bit, and if it doesn't start to flash a moment after that 10 seconds, turn the ignition off and try again until you get it right. You may have to try a few times.I used my head but you may prefer a timer or a watch.
6. Fully release the accelerator pedal while the SES light is still blinking.
7. Wait 10 seconds.
8. Full press accelerator down for MORE THAN 10 seconds this time, then full release the pedal. (SES Light will continue blinking)
9. Immediately turn the ignition switch to “OFF†position, then after a couple seconds start the car. The SES will be off!

The flashing light will tell you the 4 digit fault code, but all I wanted to do was reset the SES warning light after I had a backyard mechanic perform the necessary work.

Can you drive your car when the check engine light is flashing?
It is not recommended that you do so. You should take your automobile to an auto shop as soon as possible.
A flashing engine light means you have a condition that can cause a catastrophic failure to the cat converter. Usually this is from a missing spark in one or more cylinders. When this happens, the computer turns off the fuel injectors to those cylinders. Get it checked ASAP or you will pay much more later.
