The 2003 Chevrolet Astro Van is equipped with two oxygen sensors: one located before the catalytic converter (upstream) and another located after it (downstream). These sensors monitor the exhaust gases to help the engine control module optimize fuel efficiency and emissions. If you're troubleshooting issues, it's important to check both sensors, as they work together to ensure proper engine performance.
