mass airflow sensor mine did the same thing and that's what fixed it for me...
sensors for what? The engine has sensors as well as the brakes, steering, air conditioning and numerous other systems. You need to state your specific problem so that you will get an answer.
Have the system checked for codes. That will lead you to the problem.
I have had a lot of issues with a 1995 Mazda millinia S. The problems I have been having has been O2 sensors, and engine coolant sensors which cause the engine to misfire. If you have a code reader it will show that the problem is a misfire issue. Mine only has the problem after the engine has been at operating temperature and then the problems strike. It is a cheap fix but it worked for me.
Your VW Beetle check engine light comes on when there is a problem with one of a number of sensors on the vehicle. Take the car to the dealership to have them determine the engine problem and reset the light.
Just because you had it serviced and had brake work will not necessarilly stop the engine check light from coming on. It could have a new or re-occuring problem so that is why the engine light is probably on. The engine has several sensors that it gets information from and if any one of them sensors has a problem it can turn the engine check light on. Go and have it scanned to find out what the code or source of the problem is.
If the check engine light it on a 2002 Hyundai Accent on one of the sensors is malfunctioning. The computer is acknowledging this and alerting the driver that there is a problem in the engine.
It could be a "slight" problem with the electronic sensors. If a "check engine" light is on, the computer has detected a problem with the sensors. You need to use a code scanner to detect the fault code.
The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions.
You can not reset your oxygen sensors. You can only replace them. To reset the check engine light you will have to get that done by a repair shop with a computor. If replacing the sensors does not repair the problem then check for a vacuum leak.
There are sensors all over the engine and transmission. There are also sensors at the wheel bearings and in the exhaust.There are sensors all over the engine and transmission. There are also sensors at the wheel bearings and in the exhaust.

Black smoke means the engine consumes too much gas - possible problem with fuel injection. Is your check engine light on? It could also be a problem with oxygen sensors.
