Could this be the fix for the check engine soon light? I have sent 2 images. The first picture is the EVAP vent valve/canister purge valve in the engine bay and the second picture is the EVAP vent solenoid/ canister vent by the driver's rear tire.

Hello thanks for using 2CarPros. This code is for a small leak in the evap system. These leaks can be very difficult to find. While replacing these 2 parts might help fix this problem, inspecting the rubber lines for dry rot and cracks is going to important as well considering the car is 20 years old. Replacing the gas cap at this point can also help with this issue. Make sure any components replaced match the new part. Here is a quick guide to help understand the system a little better as well. Hope this information helps. https://www.2carpros.com/articles/evap-system-code-repair
