To find it definitively, you'll need to:
* Consult your vehicle's repair manual: This will provide diagrams and precise locations for all sensors.
* Use a repair database online: Sites like Alldatadiy or Mitchell 1 offer detailed diagrams and repair information for your specific year and engine. (Subscription may be required)
* Search online for a picture or video: Search for "2004 Dodge Stratus camshaft position sensor location [2.4L or 2.7L]" to find visual aids.
Remember that working on your vehicle's engine carries risks. If you're not comfortable performing this task, it's best to consult a qualified mechanic.
