Could a flat tire make the check engine light go on a 02 cavalier?

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 AutoZone 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 is global warming a social problem?

Global warming is a social problem because of many factors. Factors like emissions for example, emissions tests are only in a few states. With more emissions tests on vehicles, this would lessen the global warming, not by leaps and bounds but it would help. If more people recycled, and cleaned up waters this could help.

Could a faulty ignition coil lead to increased emissions?

If it's weak you might have incomplete combustion or possibly an irratic misfire, but most likely the problem that causes increased emissions is elsewhere. An increase in hydrocarbons is often caused by the O2 sensor or possibly the EGR valve. You could also have a problem with plugs, distributor, rotor or plug wires.


What does the code P1443 and or 420 mean on a 96 Ford Escort?

The p1443 code means a problem with the evaporative emissions system. There could be a problem with a broken or unhooked vacuum hose. Also could be a problem with the solenoid or sensor between throttle body and evaporative canister.

You have a 2004 Cavalier and the check engine light has been on for 8 months now it says emissions large leak when it was checked any ideas?

My car was diagnosed with this problem today also. I was told by my good friend (who is also the mechanic) that the leak could be in many places and the best way to find out where is to complete a test in which 'smoke' is pumped through the system to find the area of the leak. It could be due to a hose disconnected, or, a part in the emissions system could need to be replaced. You won't know until it is properly tested. Apparently this is QUITE common in cavaliers. Good luck.


What is a purge solenoid?

It is in the emissions system to keep gas fumes from venting into the atmosphere. If you have a code for it does not mean that it is bad. The problem could be as simple as a vacuum leak.
