The camshaft sensor is responsible for detecting the position of the camshaft and sending that information to the engine's computer. If the camshaft sensor is bad, it can cause the engine to run rich, which can in turn cause the catalytic converter to overheat and emit a burning smell.
In addition, a bad camshaft sensor can also cause the engine to misfire, which can also produce a burning smell.
If you smell a burning smell coming from your engine, it is important to have it checked out by a mechanic as soon as possible. It could be a sign of a serious problem, such as a bad camshaft sensor.
