What could the problem be on a 2004 cavalier with the codes for a large leak with the emissions?

It could be an emissions problem or a catalytic converter problem.


There could be a problem with the power of common ground to the Cavalier light and sun roof. Check the fuses and wiring for the problem.


take car to autozone and ask them to read codes it wont cost anything and they will tell you what you need to fix it


Check the engine. ===================================================== There is a problem with something that effects the emissions of the engine You need to have the vehicle scanned for any trouble codes to help diagnose and then repair the problem


The check engine light indicates a problem in the engine controls or emissions system, have the computer codes read and you will know exactly what your car is trying to tell you.


There could be one hundred & one possibilities... that's why you have to plug in a scanner & pull the code or codes. The problem is emissions related... meaning the car is polluting more than it should.


Use a code reader to check the engine diagnostic code using an OBDII code reader. If it's the gas cap you may need to replace the cap then reset the diagnostic codes by following the method described in the owners manual.




Bring to a shop that has an ABS scanner to determine the problem


i have same problem--some say need to take it to dealer to get it scanned for codes---could be a cracked intake vacumm hose??---=but it is dangerous


I had this problem and took my 1990 cavalier to a shop. Nothing came up on diagnostic so they decided my ignition module and coil packs needed to be replaced. This fixed my problem but costed me around 450.00!


The abs light being on for a 2000 Cavalier indicates a brake problem. The brakes could lock up when the pedal is pushes hard, or pulse.





Your computer has detected a problem with the emissions system, it could be an improperly sealed gas cap, O2 sensor, evap problem. or just indicates the need for a tune up. You will need to have the computer codes read to find out what part of the system is malfunctioning.


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.


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.


If a car engine stalls when turning, there could be a problem with the power steering pump. There could also be an issue with an emissions control device.


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.


ACDelco 41928 trust me. Any other plug could throw CEL codes or make car run worse


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.


Could be the problem your having is not computer related.


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.
