Here's what you should do instead:
1. Obtain a diagnostic trouble code (DTC): You'll need to get the code stored in the vehicle's computer. You can do this in a few ways:
* OBD-II Scanner: This is the best option. You can purchase a relatively inexpensive OBD-II scanner at most auto parts stores. Plug it into the vehicle's OBD-II port (usually under the dashboard), and it will display the trouble code(s). This will tell you specifically what the problem is.
* Auto Parts Store: Many auto parts stores will read the code for free. This is a convenient option if you don't want to buy a scanner.
2. Diagnose the problem: Once you have the DTC, you can research it online (many websites provide code definitions) or consult a repair manual. This will help you understand what's causing the CEL.
3. Repair the problem: This is the crucial step. Fix the underlying issue identified by the DTC. This might involve replacing a sensor, fixing a leak, or performing more extensive repairs.
4. Clear the code (after repair): *Only after you've fixed the problem* should you clear the code. Many OBD-II scanners have a function to clear codes. Some auto parts stores will also do this for free. After clearing the code, drive the vehicle for a while to ensure the problem is resolved and the light doesn't return.
Important Considerations:
* Ignoring the light is risky: Driving with a malfunctioning system could cause further damage to your engine or other components.
* DIY vs. Professional Repair: Depending on your mechanical skills and the complexity of the repair, you may choose to fix it yourself or take it to a mechanic.
* Code Readers vs. Scan Tools: Basic code readers only tell you the code; more advanced scan tools can give more detailed diagnostic information.
In short, don't try to trick the system into turning off the light. Address the root cause of the problem to resolve the issue permanently and safely.
