you've got big problems take it to a shop The engine is mis-firing, and allowing unburned fuel to get to the catalytic converter. IT may cause it permanent damage if it melts down. DON"T DRIVE IT IN THIS STATE. 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. 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
The check engine light, on your Hyundai Elantra can be reset by removing the fuse. Keep the fuse out for 10 seconds and replace it to its slot.
No the check engine light will not come on
take it to the autozone they check the engine light for free
A flashing check engine light normally means you have a misfire.
and what code does the check engine light say ? go by autozone they will check it for free and get the code.
1990 Mazda 323:The check engine light intermittently flashes a series of long and short intervals. A long flash is followed by 5 short flashes. Then another long flash is followed by 7 short flashes, a pause, and 9 more short flashes. How should I interpret this code?
If the check engine light flashes an engine cylinder misfire has been detected Avoid any heavy acceleration / decelleration and have the vehicle scanned for any trouble code(s) in order to diagnose and repair the problem
The engine is not hitting on all cylinders or the distributor (electronic or manual) needs adjustment.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
An engine misfire has been detected
Cycle the ignition on/off/on/off/on and count the flashes of the check engine light. A pattern of two flashes, pause, two flashes would be a code 22.
It means you have an engine misfre.
engine is about to stall
Disconnect the positive battery cable for a couple of minutes.
take it to autozone and they'll tell you fro free
When you get a po300 code and the check engine light flashes it to let you know to turn off the enging because you are starting to damage the catalatic converter, I screwed up mine by driving it it was a bad cam sensor
misfire .. probably bad spark plug wire.
A flashing check engine light is usually a misfire.
P0300 is a random cylinder misfire. Ensure engine is properly tuned.
The 1995 Chevrolet Geo flashing amber engine light is an indication that the engine needs to be checked soon. A red flashing engine light is an indication the engine needs to be checked immediately.
Yes, this is often the reason why the check engine light comes on.
the check engine light comes on for many reason or many parts usally emmision related.
If your check engine light is flashing that means an engine cylinder (s) misfire has been detected what is a engine cylinder misfire and how much bdoes it cost to fix it
It can only mean one thing "Check your engine"
