The code may go away by itself after a few restarts. You can also try clearing the code by taking the vehicle Auto Zone, Advance Auto or another chain parts place and using their loaner scanner to complete the task.

The engine management light is on, and the air bag light is illuminated in red on the dash. The heater is not blowing hot air, although the coolant level is fine. There is a 'whirring' noise


I suggest scanned the computer car in order to know what fault codes is stored there.

When the light comes on, one or more diagnostic trouble codes (DTC) are stored in the engine control module. These DTCs remain even if the light goes out. To address a Check Engine Light problem, the DTCs are retrieved and the appropriate troubleshooting information is followed in order to determine the problem.

The Four Most Common Check Engine Light Scenarios and What to Do:
* The Check Engine Light turns on and off or flickers.
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

* The Check Engine Light light comes on and blinks in a steady pattern while driving.
Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

An orange warning light shaped like an engine has come on what does it mean


Engine warning light

eng_man_light_72.jpg Illuminates when the ignition is switched on. It should extinguish as soon as the engine starts.
If it illuminates with the engine running, it indicates a malfunction with the engine management system. Have this checked as soon as possible.
If it flashes when driving, reduce the vehicle speed immediately until the light illuminates constantly. If it continues to flash, avoid heavy acceleration and high engine speed, stop the vehicle and have it checked immediately.
On some vehicles this light may be red - again stop the vehicle and seek assistance.
If it is safe to do so, try stopping the vehicle, switching off the engine, wait two minutes, then restarting the engine to reset the engine management system.
With the light illuminated, the vehicle is still safe to drive as long as no other faults are apparent with the engine. Have the vehicle checked by a dealer or garage as soon as possible to avoid any damage being caused to the catalytic converter

What ti do when the check engine light jeep grand cherokee 99 comes on? Also have the Air Bag light on too - is it a sensor issue and can i drive safely with the lights on?


The check engine light may not be a big deal if your Jeep is running OK. The bad news is that the airbag light has to be taken seriously.

It is normal for the airbag light to come on when you start your car and then go off in a few seconds, when the system is performing a self-test .When your airbag light stays on, it means that the circuit that controls airbag deployment has detected a problem. You need to have this looked at by a good mechanic, or preferably a Jeep dealer as soon as possible. It is possible that when there is a problem with the airbag circuitry that it can deploy without warning and can cause you to lose control of your vehicle.

I do not recommend that you try to work on any airbag system yourself. The actuators contain small explosive charges that can seriously injure or even kill you. The system is designed to store an electrical charge and airbags can be set off even with the car battery removed. If you set your airbag off and are fortunate enough to not get hurt, replacing it will cause enough pain- $2000 is not unusual.

As far as the check engine light goes.... under the fusebox (near the drivers left knee area) you should see an electrical connector. You can go to any good auto parts store and ask to borrow their ECM analyzer- a handheld device that plugs into that connector and will allow you to read the computer codes that are turning on your check engine light. Just follow the instructions that come with the analyzer.

If you get an ambiguous reading like "factory code" chances are that it is fuel related and changing your brand or grade of gas will usually fix it. While you have the ECM analyzer connected, you can clear the codes and see if the light comes back.

I have a 2001 Grand Cherokee and during the winter, one certain brand of gas will cause the check engine light to come on in the winter. This is because federal and state clean air laws require that in winter months, the gas formulation be changed to help reduce emissions... and different brands actually DO have different formulations. Try a different brand gas for a while. Also, if your Jeep has the "straight six" engine, it is very important that you always run only regular grade- this engine (IMHO one of the best engines ever made!) does not like higher octane fuel and using mid-grade, or especially premium, will give you a check engine light, along with reduced gas mileage.

I was driving the check engine light started to flash then stayed on, my car started to sputter then it just died. No belts are broken that was checked and I have a full tank of gas. Any suggestions on...


Hi, the best thing to do is to get a scan of the OBD2 connection under the dash, write down the trouble code, and send it to us. If the car will not start, you'll have to have someone bring a scanner to the car. You may have a friend that has one, or maybe the parts store will let you borrow one. I've had good luck with autozone allowing me to borrow tools--they will put a charge on your credit card and then a full refund when you bring it back. Ask them how to use it--it's not hard to learn. Without the code, we are shooting in the dark on this problem.
If you just cannot get the scan, read my tip on starting problems. If you can do some simple troubleshooting, you can narrow the problem down and maybe get lucky. Here is the link: http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines

2005 C240 Wagon Check engine light on


The reason your light is on is because the system detected a problem related to the engine(emmissions system). Usually benz recommends premium grade fuel. It is possible that the plugs have fouled or some misfiring occurred and the system illuminated your light. Do you remember seeing the light flash at all before it remained constant. When the gas cap is left loose or the seal is worn out the M.E. module sets a p0440 codes(miner leak in evap) or a p0442(major leak in evap. The first thing I would check(assuming the car is running o.k.. is the gas cap tightness. Either way you will have to take the vehicle in and have the codes read and erased. If the module notices a problem during a key cycle within 17 minutes of vehicle operation it stores a fault. One the 2nd key cycle if the module notices the same problem with in 17 minutes it turns the light on. Hopefully I have been helpful
