How do you reset dodge caravan check engine light?

You can't simply "reset" a Dodge Caravan's check engine light without addressing the underlying problem. The light illuminates because the vehicle's onboard diagnostic system (OBD-II) has detected a fault. Resetting the light without fixing the issue will only cause it to come back on, and potentially lead to more serious problems.

Here's the proper procedure:

1. Identify the problem: The most crucial step. Use an OBD-II scanner (available relatively inexpensively at auto parts stores) to read the diagnostic trouble codes (DTCs). These codes will tell you *what* the problem is. Generic scanners will give you a general idea, while more advanced scanners can provide more detailed information.

2. Repair the problem: Once you know the code(s), you can research the likely cause and either fix it yourself (if you're mechanically inclined) or take it to a mechanic for repair.

3. Clear the code (after repair): After the repair is complete, *then* you can clear the code using the OBD-II scanner. Many scanners have a "clear codes" or similar function. Some auto parts stores will also clear the codes for free if you bought the parts from them.

Do not attempt to reset the check engine light without first diagnosing and repairing the fault. Ignoring the light could lead to further damage to your vehicle, reduced fuel economy, and even safety hazards. The check engine light is there to protect your car – heed its warning.
