Diagnosing and Repairing the Check Engine Warning Light Issue


The dashboard of your car is the place where the car gets to connect with you. it is a place where picture of the entire car is presented to you in a nutshell, through different indicator and warning lights. All these lights glow up, whenever you start the car. But they also disappear, within a few seconds as soon as your car starts moving.

But when things are not in perfect tune, one or more of these lights can stay back, only to grab your attention and let you know about the fact, that something is wrong somewhere. The “check engine” is also a message we get to see often on the dashboard in the same pattern. It is one of the warning lights that is meant to get turned on automatically, whenever any part of the engine or related to it is in trouble. At the Hayden Lake check engine light repair center, we were demonstrated with live example, how the “check engine” light is treated both by the car users and the mechanics, when it chooses to stay back, or starts blinking.

What Triggers the Light?

There are several reasons that can make the “check engine” light get turned on and stay back. But whatever the reason might be, it surely has to do something related to the engine compartment. Actually, it is the onboard diagnostic system inside the car that detects an issue in any of the mechanisms that is directly or indirectly related to the engine. It automatically starts sending messages to the car user, to inform him or her, that something is not right in the engine compartment. To make it precise, the system turns on the “check engine” light. 

Situations like a loose gas cap, a fused spark plug, low engine oil or dried up coolant, a disconnected electrical wiring, or a faulty oxygen sensor as well as a damaged catalytic converter, can turn on the “check engine” light and that too without fail. 

Diagnosing the Issue

There is a strict methodology followed at the authorized auto repair centers to diagnose and detect the issue that turned on this waning light. At the first stage it is the reading of the onboard diagnosticsystem, the mechanics rely upon. They start with decoding the message. Then they go ahead with the repair process of the part, that is at fault. 

Treating the Issue

At the first place, when the “check engine” light gets turned on, the car user himself or herself can try a few DIY techniques to resolve the issue. They start with the simplest things like checking the gas cap, the spark plug, the wiring etc. if it doesn’t work, then it is the best to call roadside assistance and get your car towed, if the car reuses to move. When the light starts blinking, it says about a more serious damage that will need a costly repair or part replacement, warned the team leader of mechanics who run the center for CEL diagnosis & testing near Hayden Lake.
