Leaking fluid

I have a 96 geo prizm and there is a leak coming from one of the tubes. the tube is under the power steering fluid tubes on the right side of the engine. dont know if it is oil or transmission fluid. Also it made the check engine light come on if that helps. any ideas?

A leak shouldnt light up your CEL…look into that. We will need the CEL engine code to diagnose. You will need to provide more about this fluid. What color is it? Did you find it on the ground? If it is black…then it is engine oil. If it is Red…its tranny fluid… Yellow and sweet tasting…(dont ask) its Coolant…You dont have many other fluids in your vehicle…so
