I would disconect the negative battery cable for about 10 minutes to reset the computer. If the light comes back on then you need to get the codes read.
AnswerPull 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.The " check engine light" is by far one of the most misunderstood technological advances by the public. I am sure I will revise this as time goes on, as it is an in-depth understanding for the public. It is a warning light that is illuminated when there is a problem with 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� that are set based on a pre-set mileage.
Answeri tried all the above and still no solution, i took mine to a Dodge dealer and they found a corrodied wire going to the sensor which contributed to the problem ,after it was repaired , Avery thing was fineThat is the check engine light.
A flashing check engine light is an indication of an engine misfire.
A Dodge Ram will have a check engine light appear when the engine needs to be serviced. You can reset this light by following the directions in your manual or by having your mechanic do it.
You will need to get the cause of the check engine light repaired.
You reset the check engine light with a scan tool after repairing the failure.
That is the check engine light. Looks like a picture of an engine.
If the check engine light is blinking on your 2005 Dodge Stratus, you most likely have a sensor that is damaged or requires replacement. You can check this by accessing the diagnostic computer at the dealership.
a 2000 dodge ram 1500 the check engine light is on and the code says torque converter and clutch and overdrive solenoid. what do you think that the problem is?
The check engine light does not come on for an oil change.
The check engine light has nothing to due with an oil change.
If the check engine light is blinking on your 2005 Dodge Stratus, you most likely have a sensor that is damaged or requires replacement. You can check this by accessing the diagnostic computer at the dealership.
