I got the same error for my '02 Honda Accord EX with ULEV. Has anyone tried using Bosch 13512 part number? I've tried all places for a suitable sensor for my vehicle but none of the store guarantee that my codes will disappear and refuse to take back the product if it doesn't work. I'm over due for inspection and just want to get the part that works. Please help me with your experience on which part is best for ULEV engine.
