What does the red lightning bolt mean on a Chrysler 300?
1. Problem with electronic throttle:
The most common cause of red lightning bolt on Chrysler 300 is a problem with the electronic throttle system.
The cause of such a problem can be plenty. However, the red lightning bolt indicates a problem with this system.
2. Dust and contaminants:
The red lightning bolt can start blinking whenever there is excessive dust and contaminants in the vehicle or if you haven’t opted for servicing the car for an extended period.
The good news is that when dust and contaminants are the problems, it becomes effortless to service your Chrysler 300 and clean it. Once you remove the dust and contaminants, it becomes easy to get rid of this problem.
3. Faulty onboard computer:
These days, every function of the vehicle is controlled with the help of the onboard computer. The onboard computer decides when the red lightning bolt symbol blinks and when it does not.
What if the computer itself is faulty?
While the computer is highly reliable, it can develop a fault in rare cases.
That is why, when the red lightning bolt starts blinking, you have to figure out whether it is due to the faulty onboard computer or some other reason.
4. Faulty sensors:
Ultimately, it is the sensors that detect the levels of dust, contaminants, or the working of the electronic throttle system.
While the life of the sensors is easily around five years but in some instances, they might suffer from extensive wear and tear. Consequently, the sensors might provide faulty readings to the car’s onboard computer and various other car systems.
In that case, the red lightning bolt can also start blinking.
Faulty sensors are another reason why this problem can occur.
