i checked the diagnostic trouble codes for my check engine light and was given a 44
lean exhaust/ 02 sensor voltage low.
does anyone know if this means i need to replace the 02 sensor, and if so where is it?

Need more info. How many miles on car? If high mileage I would suspect you need to change the sensor. It should be located in the exhaust system engine pipe before the cat or sometimes located in the exhaust manifold. Good Luck :)
