What could be wrong when the CHECK warning light comes on on a 1996 Toyota Camry?
I was told if you over fill your gas tank, a filter that sits near the top of the tank that redirects unused gas vapours malfunctions. The charcoal filter gets saturated with gasoline and will require some time to dry out before you can reset the warning device. Let your tank go low and remove the gas cap over night. Next morning replace the gas cap and start your vehicle. To reset the code several restarts will have to be performed before the code is reset. I was told 15 times. Good Luck and next time do not over fill your gas tank. God Bless... Take it to a mechanic, it could mean a lot of things. If you take it to a mechanic, they can plug in the computer to read what is wrong with your car. There are "monitors" or self tests the computer runs the car through a drive cycle, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. OR hook up a scanner that is capable of clearing codes, and hope that none are still active. Disconnecting the battery can create other headaches and will not likely solve your dilemma. Best bet is to contact the local snap-on dealer and have him refer you to a known good shop that specializes in this technology-he will know. The " check engine light" is by far one of the most misunderstood technological advances by the public. This is an needed in-depth understanding for the public. It is a warning light that is illuminated when there is a problem affecting the EMISSION SYSTEM only. Emission system being the pollution control system. Don't get a hard on against it as it is a good thing once you understand it. One point that was brought up a a recent meeting of technicians was that the amount of hydrocarbons is greater when the gas cap is left off than when the engine is running. Hydrocarbons are part of pollution emitted as gasoline evaporates. Going a step farther, one facet of the emission system is the "Evaporative" portion. This is when the fumes from the gasoline are leaking from the system into the outside air. This is one part of the emission system that can trigger a check engine light. I would say that about 7% of the vehicles that have a check engine light are the result of a loose or inadequate gas cap. But understand that many scenarios are possible with the "check engine light" The vehicle's powertrain computer (note that some vehicles have 17 different computers) will run a series of self-tests. They will only run under certain criteria. And they can be vastly different from manufacturer to manufacturer. Some self-tests are not run until preceding ones have run successfully. So if there is a problem in one particular area that is preventing another self test from running, you can have a situation where one problem is fixed, but another still exists. If you fix a problem and drive the car through a drive cycle that sets the monitor (or self test) the light will go off as it passes that criteria that triggered it in the first place. After 1996, the auto industry went to a idea called OBD II (on board diagnostics). This was to get all the manufacturers onto a similar plane for troubleshooting and powertrain control. While they still differ vastly, many corrections and adaptations were made for technicians to better fix the check engine light problems. Prior to this there were so many different and poor troubleshooting data from a check engine light problem that resolving the problem was much more difficult. Many early warning light of this nature were set to illuminate based on mileage. An Oxygen sensor was one of the things that were meant to be replaced when that mileage was hit. This is much like many current "Change oil lights
This is a pump that sits underneath your front bumper on the passenger side. It is about the size of a baseball and has two hoses going into it. I would suggest you replace it yourself as it would cost you about $360.00 if you were to go through the dealer. If you would like pics. of it you can feel free to e-mail me at uscg6060@juno.com I am going to be going to the dealer to see if there is some kind of re-call on these pumps seeing as how I am about to go on my fourth one and my truck is only a 2000 S-10 you out some.

AnswerWater intrusion is what will typically kill these electric pumps. There is a Technical service bulletin (#04-06-04-015) Regarding this problem, according to the tsb, you will need a new pump and there is a hose assy. #12590627) that has you reroute the pump from future water intrusion or it is gaurenteed to fail again.I found this air pump and hose kit on Ebay.I did a search for S10 air pump.Great price on the new pump and they will ship the hose kit if you want order it.Fast shipping also.Total price for both pump and hose kit considerably less than a dealer. Although I have had water in the pump I did not see any indication of the inlet hose as the cause. It was suggested that the one way metal check valves ($15.00) that mount to the rt & lt exhaust manifold are worn and allow water from the exhaust to get sucked back into the pump. I first replaced the pump and within a week of dry weather driving the light came back on. I checked the pump and it was again full of water. I just replaced the valves which had deteriorated on the inside. So hopefully this will eliminate the problem. Note - The valves are impossible to remove without removing the 1/2 tubes (held on with 2 nuts) they are attached to the manifold with. The valve threads sieze to the tube thread and had to be clamped in a vise to remove - I actually had to hacksaw the valve section to get it off the pipe. Careful as not to damage the threads.

Thanks this is very helpful, just thought I might add something. I have had the same problem with water in the air pump on my 2000 Chevrolet Blazer 4.3 L V6. I went on eBay and searched for the pump like you had recommended and I found a pump for sale by seller:autopartsdirect2you ,any way the lifetime warranty offered by these guys is great. The problem is with water gettin ginto the air pumps, and the warranty covers it. Just thought I'd add that. I think a good warranty with this in particualr is very important
If the check engine light is on, then the car is not fine. It may be seem to be running fine, but there is a problem. Damage can occur to the engine, and especially to the 02 sensor and the catalytic converter if the problem is not corrected. The light will be reset with a scan tool after the problem is repaired. There was a recall on the Camshaft sensor, that causes the engine light to come on. You will have to contact the dealer you bought the car from and see where to take the car for warenty work. daewoo's have over 100 sensors on them any of these could set a check engine light. loose gas cap will set a check engine light.could be anything, need to get it scanned to find out. if you unplug the battery all you will do is loose you radio and have to put the code back in, not clear the problem. Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self tests the computer runs the car through a drive cycle, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. OR hook up a scanner that is capable of clearing codes, and hope that none are still active.
