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 Check the Oil Level on a Jeep Renegade?

To check the oil level on a Jeep Renegade, you need to open the bonnet to access the components inside the engine bay: on the lower left side of the engine block, you will find the dipstick for checking the level. This should be pulled out and thoroughly cleaned with a cloth: once cleaned, reinsert it back into its tube and pull it out immediately after. This way, you can check that the oil mark is between the minimum and maximum levels; finally, you can place the dipstick back in its tube.
