Check your connections on the O2 sensor for that bank The reset button is on the ECU for the bank behind the seats Clyde Romero

I'm trying to find the buttons so I can download the error codes. But it's not clear to me where they are located. Front, under one of the compartment lining flaps? I've seen the picture in the workshop manual (at C53) showing what I am seeking, and how to extract the codes.
I'm wondering whether I am having problems with an O2 sensor again. Last night I retrieved my car from my friend, who fixed my supposedly (according to a mechanic who previously had it) malfunctioning temperature sending unit problem. (The temperature gauge had been operating intermittently.) Short story is that there was nothing wrong with the sending unit (nor with the gauge). My friend tracked down corrosion on a critical connecting pin in the wiring harness.
Anyway, after having worked on the car on and off for a few days my friend had to jump start the car -- hence my separate search for a new battery -- but after that was done I drove off with no problem. Drove around 40 minutes in local traffic and everything (including gauges) seemed normal, but then the check engine light for cylinders 7-12 came on -- and stayed on, for the 20 minutes remainder of my trip home, during which everything still looked and sounded normal. This afternoon I started the car and it idled roughly, RPMs swinging for several seconds between about 1100 and 1900, then the swings narrowing before stabilizing around 1400 (which, as I recall, is higher than it normally idles). And the 7-12 check engine light was on the whole time.
