Disconnnect the battery cable for about 2 minutesmy 2 centsThe " check engine light" is by far one of the most misunderstood technological advances It is a warning light that is illuminated when there is a problem affecting the EMISSIONS of the vehicle.. Don't let it bother you as it is a good thing once you understand it. One point that was brought up 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 a small percentage 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 multiple computers aside from the powertain computer) will run a series of self-tests. They will only run under certain criteria. And they are different from manufacturer to manufacturer. Some self-tests or �monitors� 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. There are many different sources for the light to come on. Anything that caused combustion to fail, commonly called a misfire will set the light. Various sensors such as oxygen sensors that evaluate the exhaust before and after the gases are burned in the converter. Transmission codes may set the check engine light to appear. If the car is running okay, get it fixed in a reasonable amount of time such as within the month. It will probably save you fuel if you do. However if the Check engine light is flashing, you should be driving it as damage is being done to the converter. Some emission components are covered beyond the standard warranty. The converter for example is covered up to 80,000 miles by the manufacturer. 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, 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� that are set based on a pre-set mileage. To start testing for the check engine light, you�ll need to find 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. There are self-tests for the oxygen sensor circuit, egr system, evaporative system to name a few. Therefore, another problem may exist. It is emission related.
OR hook up a scanner that is capable of clearing codes, and hope that it won�t come back on. But don�t bet on it. Lastly, disconnecting the battery in some cars will clear the memory of the computer and may temporarily turn the light off. Beware that this may also cause other problems such as the car not rembering it�s idle and will have to relearn it, the radio may be rendered inoperative or in the case of the new Toyotas, the air bag can blow.
My 1997 Camry V6 gets 23mpg in town and 31mpg on hiway.
must be a oxygen sensor
Just disconnect the battery for couple minutes.
One word answer: YES
Check the signal light fuse, the signal light relay, and the signal light switcher.
disconnect the negative on the battery cable for 15 minutes and then reconnect.
common problem with 1998 mystique check engine light on
How do you reset the Airbag warning light on a 1995 Toyota Avalon?
Not sure if the 98 is the same as the 99 but the fuse box is to the lower left of the steering wheel behind the ashtray. Pull out the ashtray and fuses should be there.
This could mean any number of things. I have a 98 Tacoma and the "check engine" light has only come on once in 8 years ... and that was because I didn't have a gas cap at the time!
Press the odometer button while starting the vehicle. Keep holding down the button until the numbers disappear and the check engine light goes out. Release the button and all is well.
Yes, it can cause check engine light to come on. Reasons are multiple - anything from air/vacuum leak, spark problems etc. to major failure.
Replace the bulb that is burnt out.
Underneath the steering column
The ECU has detected a problem with the emissions system. Most auto parts stores will scan the ECU for free.

How do you change the light bulbs in the instrument panel in 1998 Toyota corolla
The correct part # is 9098114009
Opened the 1998 Toyota Camry hood compartment. Take hold of the light bulb connector. Push the connector in and turn at the same time. The light bulb will come out. Reverse the process to install the new light bulb.
How can you change the light bulb for the gear shift on a 2002 Toyota Camry?
The check engine light is the light shaped like an engine, or the light that states Check Engine (Soon). If this light comes on, it is time to see what the issue is with the engine.
hi there could you please tell me what the 100 amp fuse is powering as they normally have fuseable links to power up main branch lines to the fuse box on the camry's
On the wiper switch stick
Dead interior light fuses or the bulb if it's assumed no major problems.
What is a thermostat light?
