Apparently,... Yes. I have a 2002 Chevy Cavalier. My check engine light was coming on randomly for a week. Then, my trac off light would come on, and my car would die, while running, a few minutes later. I had my car in a repair shop for a week. The technician said he couldn't find anything wrong. I brought my car to auto zone, and they did a scan test on it, for free. The code came back to me needing a new TPS. The TPS cost me $50. I am getting an estimate on putting it in tomorrow. Apparently, the way it was explained to me, the TPS is somehow electrically connected to the ABS, which is connected to the traction. Go to Auto Zone. Get a scan.
It will usually come on. The speed sensor on my transmission died and it displayed the check engine light.
If it has a downstream O2 sensor the check engine light will come on but if it does not the light may not come out. In most instances it will set the check engine light.

it is probably throwing off a sensor, like the mass airflow or map sensor and causing the check engine light to come on
If it is bad the check engine light will come on and set a code for that particular sensor.

Check engine light will come on for various reasons. The o2 sensors could be one of them. If your belt breaks the light will come on and the engine will over heat. I mentioned the o2 sensor because when it comes on for this reason some people have had that light on for years without replacing the sensor.
