Default o2 ses light
I keep getting the ses light for low voltage on the upstream sensor. I replaced both sensors but the light came on during my recent trip to Las Vegas as soon as I started going up into the mountains.The book says its running too lean and goes into a default mode.

Is this book the Factory Service Manual? This is what Echo is asking I think.
