Why is my check engine light on but my car is running fine?
Normally, the appearance of a check engine light indicates a problem somewhere in your vehicle, but nothing seems amiss. Your car is still running at its best and there seems to be absolutely nothing wrong. It doesn’t have to take a mechanical issue in order for this light to appear.
What sensor makes the check engine light come on?
The oxygen sensor, also known as the O2 sensor, measures the amount of unburnt oxygen in your exhaust system. A failing sensor can cause the check engine light to be triggered, though you can continue to drive relatively fine with it.

What is the problem with my PT Cruiser p0340?
The P0340 has to do with the cam position sensor. This seems like a fairly common problem on PT Cruisers. With this problem the car would go into what is called “limp home mode”, where the engine will max out at about 2,500rpm. Sputtering and such seems fairly common here, also.
Why does my check engine light keep turning on?
On average, a quality O2 sensor will set you back about $175, but the cost of labor will vary greatly depending on the vehicle’s make and model, as well as your geographical location. Finally, keep in mind that most late-model cars have more than one O2 sensor. A loose fuel cap is one of the most common reasons why the check engine light turns on.
What should I do if my engine temperature warning light comes on?
Under no circumstances should you keep driving after the engine temperature warning light comes on. Overheating will quickly ruin your engine and put a big dent in your pocketbook. Turn your heater on full blast, pull off the road as soon as you safely can, and shut off your engine once you’re off the roadway.
