What could cause the check engine light to come on in a Chrysler 300?
A steady glow is an indication of a minor fault while a flashing check engine light means something very serious with your Chrysler 300 that needs urgent attention. Therefore, when this occurs, it’s important to contact Chrysler service to know the next line of action. So, here are reasons why your check engine light might come on.
Your Chrysler 300 has a vacuum leak: Chrysler 300 comes with a vacuum system that’s integrated with a lot of functions. The vacuum system regulates harmful emissions by directing the fumes as your car’s gasoline burns through the engine.
If your car’s RPM is high in idle or randomly surges, then your car has a vacuum leak fault. Over time, vacuum hoses get weak and start to crack if they have been exposed to extreme heat or speeding.
Another most common fault of the check engine light is a loose gas cap, damaged or missing. The Chrysler 300 gas cap has many purposes. It hinders the gas fume from evaporating when you’re not driving, it covers the fuel system and maintains pressure within the fuel tank.
Your mass airflow sensor (known as MAF) needs to be replaced if it’s the reason for the check light. A faulty Chrysler 300 MAF can trigger this warning because it measures the amount of fuel your car needs to run the engine efficiently.
It does this by measuring the air supply needed by your car’s engine. As part of the engine system, it regulates and adjusts changes in your engine like altitude. So, if you noticed your Chrysler 300 has an issue starting, idling rough, or your throttle has shifted from the usual state, this is a sign of faulty MAF.
The battery is low or dead. When your Chrysler 300 battery is low or dead, it triggers this warning. So, if you have a dead battery, you can’t do anything with your car until you replace it, or if it’s low, you can charge it.
New Spark Plugs or Plug Wires are paramount for your Chrysler 300. The spark plugs are there to ignite the air/fuel collection in the combustion chamber of your Chrysler 300.
These spark plugs are what cause the car pistons to move and help the engine run. The spark plug is in charge of delivering spark from the ignition coil to the spark plugs. If these spark plugs are faulty or dead, you should replace them.
Issues with any aftermarket items. An aftermarket of anything on your car like alarm, exhaust, or substituted item can cause the check engine light to come on if they’re not properly installed.
The aftermarket parts of your vehicle can drain the battery and even cause poor electric flow in your car. If you notice something like this in your car, consider taking it to a mechanic for proper adjusting and fixing.
Your catalytic converter is bad or going bad. The catalytic converter is part of the car’s exhaust system. It functions by turning the carbon monoxide produced by the combustion process into carbon dioxide.
If your catalytic converter is faulty and you don’t get it fixed sooner. Your vehicle will fail to pass an emission test, indicate poor engine performance, and will cause your fuel to drain quicker. It will also cause you fuel economy.
Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, referred to as the O2 sensor, measures the oxygen your exhaust system receives. If the sensor is bad, your car will burn fuel faster and your car will have fuel economy issues. When you fail to replace a failed O2 sensor, it can affect your car’s fuel economy and also damage your Chrysler 300 catalytic converter and spark plugs.
