What is a catalytic converter. what is oxygen sensor, or coolant temp sensor?On a 04' Volkswagen Jetta GLS 2.0 4 cylinder, and check engine light on, how much will it cost, and can I drive it until I get it fixed. It's been on since today. 5/24. Will it do much harm. Need help to understand automotive terminology and knowledge of the engine. How do they.
