Coolant: Check the coolant reservoir for adequate levels. Add the correct type of coolant if low.
Transmission Fluid: Check the transmission fluid level (if applicable) and add fluid as needed.

4. Inspect Hoses and Connections

Visually inspect all vacuum hoses and electrical connections for signs of wear, cracking, or looseness.
Secure any loose connections and replace damaged hoses as necessary.

5. Reset the Check Engine Light
