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
1999 Toyota Camry brakes light comes on on its own and goes off when you brake or turn Brakes and hand brakes engage well no problems?
To turn off the maint. req light (it comes on every 3k -5k mi. for oil change interval). After I change my oil I do the following: 1. depress and hold the odometer reset button 2. turn the ignition switch to on, then off 3 times (do not engage the starter), the third time the odometer will countdown "_ _ _ " then "_ _" then "_" then blank. 3. if the check engine light…
Why 1988 Toyota Camry will not start it cranks but no fire comes out of distributor it was running great until you change the battery you feel like you knock something loose or blown a fuse?
Handbrake warning light staying on all the time on Toyota celica how do i fix this and what causes it?
Check your gas cap to make sure it seals tight. My check engine light comes on every now and then in my 1991 Camry and once I reseat the cap it goes out almost immediately. If this is not the problem have a mechanic check the oxygen sensor. Good luck, JFD EGR Va.ve? It might be your EGR valve which is part of your emissions system. My 1997 Celica passed the emissions test but the…
What could be wrong if you had the head gasket replaced on a 1994 Toyota Camry but within 100 miles the oil light flickers and comes on steady when driving if you already changed the sending unit?
I believe that there is a button that controls this light. I drive a 95 Toyota Camry Coupe, and on my console down by the Gear Shift there is a small button labeled "PWD". When engaged (Down) the light is off, and when disengaged (up) the lGren PWD light shows on the Instrument panel. My understanding is it has to do with Traction Control Hope that helps!
How can you reset check engine light in Toyota Camry 2001 other than disconnecting battery because it is done and got back again?
If you reset the computer then the Check Engine light comes back on, it just means that the problem still exists. You need to use a code scanner, find out what's wrong, fix the problem properly THEN see if the light comes back on. Often when the problem is properly repaired the light will go off by itself and you don't need to clear the code.
