Here's the proper approach:
1. Diagnose the Problem: The first and most important step is to find out *why* the check engine light is on. You have several options:
* OBD-II Scanner: This is the best approach. A relatively inexpensive OBD-II scanner (available at most auto parts stores) can be plugged into your car's OBD-II port (usually under the dashboard) to read the diagnostic trouble codes (DTCs). These codes will tell you the specific problem the car's computer has detected. Search online for "[DTC code] Dodge Stratus" to find out what the code means.
* Auto Parts Store Check: Many auto parts stores will scan your car's codes for free. They can then advise you on how to proceed.
* Mechanic: If you're not comfortable diagnosing the problem yourself, take your car to a qualified mechanic. They have the tools and expertise to properly diagnose and repair the issue.
2. Repair the Problem: Once you know the cause of the CEL, address the underlying issue. This might involve replacing a sensor, fixing a leak, or performing more extensive repairs.
3. Clear the Code (After Repair): *Only after you've repaired the problem* should you clear the code. Many OBD-II scanners have a "clear codes" function. Some advanced scanners even allow you to turn off the light without clearing the codes. You will need to clear codes to fully turn off the CEL.
Warning: Simply disconnecting the battery for a short period *might* temporarily clear the CEL, but it won't fix the underlying problem and the light will likely return. This is not a recommended solution.
In short: Don't just reset the light; fix the problem that caused it. Ignoring the check engine light is risky and could lead to costly repairs down the road.
