Hi guys, so..... I had a P0500A speed sensor code. I replaced it and it came back 3 days later. I can't pass smog with this damn engine light on It says P0500A 1/2 confirmed, 2/2 pending. Is there more than one? I replaced the one that's located outside of the transmission. I have a 1998 Frontier. I'm at the end of my rope any help would be overwhelmingly appreciated thanks in advance!
