The other day the check engine light for my Altima came on. At the same time, the speedometer stopped working correctly. The codes indicate oxygen sensor and crankshaft position sensor. This happened once over a year ago. The shop I took it to said that a relay had come unplugged, and plugging it back in fixed it. I now live 10 hours from that repair shop.
Since the problem and diagnostics were identical I looked for an unplugged relay and found one right away. Problem is, I can't find where it came unplugged from. Image attached. Any ideas? Thanks.
