Common mistakes of Check Engine Light Diagnosis

Like most car warning lights, the check engine light appears on your dashboard when the car's system malfunctions in a yellow, orange or red engine symbol. Either it remains steady, or it flashes.

Generally, it's an emergency if your check engine light is flashing. So as soon as possible, safely pull over to the side of the road.

On the other hand, there's no cause for alarm if the warning light is steady.

Pull over to the side and calm down.

We know your head starts racing with questions when the check engine light appears on your dashboard.

The most important thing is to be calm, relaxed and think practically.

Naturally, your car is talking to you if the check engine light comes on; depending on the type of error code the computer scanner has identified, the severity of the issue depends.

This issue can be as minor as a loose gas cap. But, sometimes, it could be a faulty catalytic converter or a failing oxygen sensor that has triggered the check engine light, and those can be very costly repairs.

What is the meaning of Check Engine Light?

The sensors within your engine system send messages to your car's computer to monitor each operation in your vehicle.

The check engine light comes on to alert you once an error code is sent for any engine part that has malfunctioned. And depending on your car model, the warning light will be orange, yellow, or red. The symbol may accompany the words "check engine" with a car engine outline.

Steady Check Engine Light

The steady light means it's not a very serious issue, but it must be looked into. However, to avoid further damage, you should book an appointment with your mechanic as soon as possible.

Flashing/Blinking Check Engine Light

The safest option if the car's check engine light is blinking/flashing is to safely pull over and then shut off the engine since this indicates a more serious issue. Then, for further diagnosis and repair, you should tow your car to the nearest auto repair shop.

Solution for Check Engine Light problems

Take immediate action if there's a serious problem.

  • Check for indicators of low oil pressure or overheating in your dashboard gauges and lights. These conditions mean you should find a safe place as soon as possible to pull over and shut off the engine. On some cars, a red check engine light means stopping right now, and a yellow light means investigating the problem.

Tighten the gas cap

  • Often this one thing might help you solve the problem. But remember, before the light resets, your car might have to take several trips. Also, there are separate indicators in some vehicles which warn of a loose gas cap.

Bring down the speed and load.

  • Reduce your speed and try to reduce the demands on the engine if the check engine light is blinking or you notice any serious performance problems such as loss of power. As soon as possible, have your car checked to prevent expensive damage.

Make use of built-in diagnostic services.

  • With the ability to report on trouble codes and schedule a service appointment, many modern cars have integrated remote diagnostics capabilities. Today many automakers support remote diagnostics and the ability to schedule a service appointment, like Fiat Chrysler, Ford, Hyundai, Jaguar, Land Rover, and Volvo.

If none of the above-mentioned alternatives works for your car, bring it down to your nearest Bosch Car Services to get an authentic car checkup without getting robbed for extra money or false repairs.
