So my engine light came on tonight as I was merging onto the highway, and at the exact same time that I hit 53k miles. I've neeever had an engine light come on. Not in my first cobalt and not in this one. Is there a large array of things that could be setting it off? Is there a possibility it's an electrical malfunction because my air pressure is all backwards. It says to fill my back tires, but when I fill the back ones, the front ones go up, so I have to fill the front ones to get the back tires to fill up, according to my car.

for the engine light, the best thing to do is go somewhere like Autozone and get it scanned for free and go from there. As for the tpms sensor. Mine are like that too after I rotated my tires.

 

Get a aeroforce gauge you wont look back there amazing
