My 2000 Honda Odyssey has reached 175,000 miles and I'm looking to sell it without spending much on repairs. The check engine light is coming on due to fault codes P0420 and P1149. I'm seeking affordable solutions—any advice on how to fix these issues without expensive diagnostics or replacements?

Try replacing the upstream oxygen sensor first. If the P0420 code persists, it may indicate a failing catalytic converter. This is a common issue on older Honda Odysseys with high mileage. A simple and cost-effective starting point—good luck, and please update if you find a resolution.
