Hello good day, oxygen sensors are usually found in the engine escape in the closest part to the block, that is, in the exhaust multiple, if it has an aluminum coverage you remove it to visualize it easily, it is advisable to do it with the cold engine so as not to suffer serious burns, if the engine is in v you should know which side it is and if it has 2 oxygen sensors I still identify if it is equal to identify if it is equal to it.
