Here's what you should do instead:
1. Obtain a diagnostic trouble code (DTC): This is the key to understanding why the check engine light is on. You have a few options:
* OBD-II Scanner: A relatively inexpensive OBD-II scanner (available at most auto parts stores) can be plugged into your car's OBD-II port (usually located under the dashboard) to read the trouble code(s). This is the best and most reliable method. *Note:* While 1996 was a transitional year, many 1996 vehicles *do* have OBD-II. Check your owner's manual or the sticker on your driver's side doorjamb to be sure. If it doesn't have OBD-II, skip to the next option.
* Auto Parts Store: Most auto parts stores will scan your car's computer for free. They can tell you the trouble code and often give you an idea of what the problem might be.
* Mechanic: A mechanic will have the tools and expertise to diagnose the problem accurately.
2. Address the problem: Once you know the DTC, you can research the problem online (many resources are available) or consult a repair manual. The problem could be anything from a loose gas cap to a more serious issue requiring professional repair. Do not ignore the check engine light.
3. Repair the problem: Fix the underlying issue identified by the DTC. This might involve replacing a sensor, fixing a leak, or performing other repairs.
4. Clear the code (if necessary): After the repair, some OBD-II scanners allow you to clear the code. Your car's computer will often clear the code automatically after a certain number of successful driving cycles if the problem is fixed. If the light stays on after a repair, there might still be an issue that needs addressing.
In short: Don't focus on turning off the light. Focus on fixing the problem that's causing the light to turn on. Ignoring the problem could lead to more serious (and expensive) damage down the line. If you're not comfortable working on your car yourself, take it to a qualified mechanic.
