To find it, you'll need to look under the hood. It's typically located in the lower intake manifold area, near where the upper and lower radiator hoses connect. However, the exact location can vary slightly depending on the engine's specific configuration. You might find it helpful to consult a repair manual specific to your 2004 Chrysler Sebring 2.4L convertible. A Haynes or Chilton manual would be a good source for diagrams and detailed instructions.
