What can be the main causes of the engine warning light being on

Model: (Various brands) Various
Part: Warning light – error code

The video illustrates some very common causes: the first is the exhaust system in general. So the lambda probe or faulty oxygen sensor, the inefficient catalyst or FAP, the clogged or faulty EGR valve. Follow fuel or combustion problems, such as defective injectors or worn ignition coils or spark plugs. But there may also be problems with the electrical system such as dirty or faulty MAP or MAF sensors. And what about really serious mechanical problems like a slipping timing belt? Even the lack of just one tooth can cause the warning light to come on and serious operational problems; and problems with the vapor recirculation system can trigger the warning light. If it is yellow, it allows us to reach a mechanic for a diagnosis. If it is red, we must stop immediately and call a tow truck. Continuing could cause serious damage to the engine.

How to Open the Bonnet on the Lancia Y

To open the bonnet on this vehicle, follow these simple instructions: first, open the driver's door and locate the lever positioned just below the dashboard, marked with an image of the vehicle with the bonnet open. Pull this lever towards you until you hear a "click" indicating the bonnet is released. Next, exit the cabin and stand in front of the bonnet to disengage the safety catch and complete the opening. To do this, slightly lift the bonnet, locate the yellow lever underneath, and pull it to the left to fully release and open the bonnet.
