Engine Light Flashing: Meaning, Causes, and Fixes

Once your dashboard starts blinking that orange or red “check engine light, then it is usually time to get concerned. Majority of the people turns a blind eye to it until it becomes a major problem & you may have to look for some used auto parts pretty soon.

Flashing engine light is an indication that the engine might have some serious problem. It is not some minor sensor glitch; it is frequently a physical mechanical or electrical problem, which has to be addressed.

The Flashing Engine Light in Used Auto Parts

One constant check engine light with a flashing one is totally two different scenarios. When it is stable, then you may run home and review it later. However, when it flashes, the computer on your car has sensed that something serious has occurred and it will most likely be a misfire, which is capable of breaking the catalytic converter.

Misfire refers to the inability of one or more of the cylinders to work properly. That may result in unburned fuel travelling to the exhaust that overheats and may even melt parts. Driving any further would mean costly repairs.

Usual Reasons of Flashing Engine Light

It is not one reason that this is the case. Automotive vehicles are complicated and that light would signify a number of potential problems. Nevertheless, such are the most prevalent ones:

  • Engine Misfire: This is the most widespread cause. Misfires occur when combustion of air and fuel does not take place in the combustion chamber. This may be through faulty spark plugs, faulty ignition coils or faulty injector.
  • Malfunctioning Spark Plugs/Ignition Coils: They will not ignite the fuel mixture in case of they being old or damaged. That causes undue idling, decreased power and that flickering light.
  • Clogged or Failing Fuel Injectors: Clogged or dirty injectors may cause the ratio of fuel and air to become unbalanced and cause a misfire.
  • Bad Sensors: Oxygen sensors or mass airflow sensors are used to help control the amount of fuel entering the engine. In case of failures, a computer is unable to adjust appropriately.
  • Damage to Catalytic Converter: Long term misfires cause unburnt fuel to flow through the exhaust. This causes the converter to overheat and burn up a very expensive repair that would lead some to begin searching used parts rather than buy new ones.
  • Low Compression or Internal Damage: There are other situations where it could be not sensors or spark plugs but actual internal damage, such as a blown head gasket, broken piston or valve wear.

How to react when the light begins to flash

Looking where to go on the road, flashing engine light could indicate a need to reduce speed and decelerate throttle. Pull over as soon as it’s safe. You can begin with inspecting the fundamentals- just ensure that the gas cap is closed, as this for times causes an ignition to the light. Next, connect an OBD-II scanner to scan the error codes. Even the low priced scanners will guide you in the right direction.

In case the code indicates such a phrase as P0300 (random misfire), the problem may be minor. However, when it has a cylinder-specific error, such as with P0302 (misfire cylinder 2), then you probably have an issue with a defective ignition coil or spark plug or an injector. That can be repaired using used auto parts within a budget.

DIY Fixes You Can Try

Change the spark plugs first they are inexpensive and are a frequent cause. Incidentally, when you are there spare time and check ignition coils, look against the cracks and burn marks. That light can be eliminated just by changing a pack of simple coils.

Provided that the problem continues, check the air filter and clean MAF sensor using proper cleaner. In some cases, a dirty sensor supplies erroneous information to the ECU and upon which the light is switched.

In the case of the cost conscious who prefer keeping their expenses minimal this comes in handy by visiting the used auto parts shops or the internet sites. OEM ignition coil, injectors or even half the price of new sensors are available.

When to Change the Engine

When all the indicators of the diagnostic codes are low compression, fouls in the oil or repetitive misfires despite replacement part changes, you may be in the midst of more engine issues. Internal damages are very costly to re-assemble, particularly in case of re-assembling.

Most of the mechanics would suggest a replacement engine, in that case. The huge cost of rebuilding is avoided with the discovery of car engines that are sold. Established suppliers provide proven and certified engines which have an almost new running history and come with warranty.

Why Used Auto Parts Makes Sense

No flashing engine light is a requirement to buy a new car. Several intelligent parts replacement can sometimes correct the problem permanently. This is the reason why most drivers use second-hand car parts. They provide OEM quality, are a perfect fit and are much cheaper than new parts.

It could be an ignition coil, an O2 sensor, or even a catalytic converter, but testing the used auto parts that you use can help save you some money and help give your car some life. Also recycling old parts will reduce wastage, and this is another victory.

On larger ones, such as engine replacement, car engines purchased by certified vendors are usually accompanied with compression as well as leak-down tests performed prior to shipment. That will provide you with some relief that you are not putting another issue together.

Final Thoughts

In an instance where it turns out that the damage is substantial, there is no need to necessarily scrap the vehicle. You have an option of checking out car engines for sale offered by reputable dealers, and restore your car on the road at an affordable price. Combine that with quality used auto parts and routine care and you can get out of that car very easily with another hundred thousand miles to travel.

Then, when that light is flashing, do not take it lightly. Check the codes, repair what is necessary, and in case it is necessary, replace smart, not expensive.
