Code P0140
I was on my way home yesterday and SES light came on, stayed on solid. I stopped by local Advance Auto to have code read and P0140 came up. Something about O2 sensor circuit- no activity detected (Bank 1 Sensor 2). Thought I'd check in with you guys for assistance. Car has 149,000 miles on it. Front sensor was replaced about 5-6 weeks ago but rear O2 is still original.
