Kia Optima THAT shuts off WHILE DRIVING: THE PARTS CONCERNED
We will in fact help you with your research on the origin of your Kia Optima that dies while driving. Examine all elements that if damaged will be the cause of the issue you are encountering.
THE EGR VALVE
The EGR valve is one of the elements that make a lot of hassle for drivers. In actual fact, this valve has a habit of clogging up the more time passes or due to a “quiet” driving of your Kia Optima. This can result in poor exhaust gas diffusion and, when it is completely blocked, a loss of power and possibly stalling at idle. Read this complete article to EGR valve problems for more info.
A GROUND WIRE OR ELECTRICAL HASSLE
Does your Kia Optima shuts off although driving? Don’t forget to have a look at your electrical system, if it’s a ground wire, for example, which can cause a short circuit, or a totally damaged electrical circuit that can no longer carry electricity. This is one of the most difficult causes to detect… We suggest that you try to locate a “burnt” part for the ground wire, which would present that an electric arc has created between a cable and the bodywork, however you will absolutely have to contact a professional to fix this issue.
IDLE ACTUATOR
The purpose of this component is to control the engine idle speed of your Kia Optima. If your Kia Optima engine unit stops without warning when you’re at a standstill, such as at a red light, verify the level of wear on your actuator.
THE FUEL PUMP
One of the most rational motives, without fuel, the engine stops running. Often, over the years, the fuel pump filter can become clogged or the fuel pump is weak and no longer pumping. Either method, your Kia Optima could stop although driving.
FUEL INJECTION SYSTEM
Same reflection as seen previously, however, in this situation it is the last phase of the fuel intake into the engine. Seized injectors, a faulty injection pump or sensor and your Kia Optima can go out of service or completely disable your fuel injection. An injection issue will usually appear when the fuel injection is hot.
NEIMAN ISSUE
A neiman, mainly concerning its ignition switch, will often cause you trouble and cause your Kia Optima to stop although driving. This part, which is necessary for starting your motor vehicle, also serves as an anti-theft protection, which will prevent your Kia Optima from running normally if it fails.
IGNITION COILS (PETROL ENGINE UNIT ONLY)
The penultimate most important explanation an Kia Optima stops although driving is the ignition coil. This origin is only relevant for petrol cars since the engine runs by explosion and not by compression. In case your coils are too worn out, they will no longer spark. Look on that side.
BATTERY / ALTERNATOR
Finally, it is also possible to be the victim of a tired battery or a damaged alternator. In both cases, the lack of energy stored inside the battery will prevent your Kia Optima from running as it will no longer be able to power the most important parts of your engine unit.
