The 2nd time the light went out before I got to the dealer after (2-3) weeks and about 1000 miles. Has anyone else had problems with getting 02 sensors wet?

Happened to me. I got my engine moderately muddy. Drove on it for a few weeks. Then hosed out the engine, immediately the "check engine light" came on. Waited a few weeks (maybe 1000 miles) and took it to the dealer. Paid $100 for the dianostic. It didn't need a new o2 sensor. The old one just got cleaned out and put back in.
Where is the o2 sensor, so I can not blast it with water next time. anyone know?
