Question edited for clarity.
Question moved to model category.
As a general rule, with a laterally positioned V6 , Bank 1 is always closest to the firewall Bank 2 is closest to the headlights.
Sensor 1 is ALWAYS the one in the Exhaust Manifold, and Sensor 2 is ALWAYS the one AFTER the Catalytic converter.
confirmed here
Well the dash lights and headlights are on two different circuits, but both are controlled by the headlight switch. Do you have power in and out of the switch for both circuits ?
You have to understand that when you have anytype check lamp or malfunction lamp lite on yourdash, you not resetting things. Your vehicle has detected a problem that has to be diagnosed & repairedThis technology started in north america in 1983 some30 years ago,yet there a hundreds of these questions a day, just on this web site,which tells me, people could careless & drive until the vehicle quits & ends in an expensive repair,most of which is diagnostic time to find the issues.You surely know about checking for codes & having thesystems the codes point to component tested & thecause of a check light repaired if necessaryABS-anti-lock brakeTSC-traction control systemThese can't be strange to anyoneAnytime you get any light on your dash & you will get one a year you have it checked for codes &within a day or two. Otherwise stop using itThen you have a good idea if you should be drivingit until you make a repair shop appointment or repair yourself,that you will do within a week or so.
which engine is it. and USA car?
did you even look first. seems not to me.
why not go to Valvoline oil changers, and let them do the mess.
no split oil.
here it is, me reading your manual < LOST IT:
?

Take it to a good local auto-electrician as advised.

Have it checked for DTC'S - diagnostic trouble codes , before you start playing with thing's . All the gauge setting information comes to the instrument cluster over serial data network GM Class 2 from the PCM/ECM engine computer . Could have U codes stored, Do you know anything about serial data networks or U codes ? If not, do yourself a favor an have a qualified repair shop check it.

Fuel Gauge
The instrument panel cluster (IPC) displays the fuel level based on information from the engine control module (ECM). The engine control module (ECM) calculates the fuel level based on information from the fuel level sensor. The engine control module (ECM) sends the fuel level information to the body control module (BCM) via the serial data circuit. The instrument panel cluster (IPC) displays the fuel level as received from the BCM. The fuel gage defaults to E (empty) if:
• The ECM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of serial data communications with the BCM.
• The BCM detects a loss of serial data communications with the ECM.
When the fuel level is less than a pre-determined value, the Low Fuel indicator message illuminates.
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on information from the engine control module (ECM). The engine control module (ECM) calculates the vehicle speed from the vehicle speed sensor (VSS) input. The ECM sends a serial data message to the BCM indicating the vehicle speed. The instrument panel cluster (IPC) displays the vehicle speed as received from the BCM via serial data circuit.
The speedometer defaults to 0 km/h (0 mph) when any of the following occur:
• The ECM detects a malfunction in the vehicle speed sensor.
• The BCM detects a loss of serial data communications with the ECM.
• The IPC detects a loss of serial data communications with the BCM.
The plug cables could be worn. You can't tell from surface inspect or test each one. The boots or connection is common to wear. Also ignition module may have issue. The timing or fuel delivery may be hidden problem
I have a 2008 Saturn VUE. I had the problem where my key would not turn to off and I wouldn't be able to take it out of the ignition it was also on ACC. So even though I had power in my car it might be the same problem you have. I just kind of hit the shift up when it was in park. This should unlock the key. You should hear a click and after that you should be able to turn it all the way off and take the key out.
Not sure on that particular model, as some have a filter screen in the filler neck preventing a tube from being stuck down into the tank. Only one way to find out, stick a piece of garden hose down the filler neck ( use about a 4 foot section) if it only goes in a few inches to a foot, you will have to drain the gas by disconnecting the fuel line at the tank and pressure pump it out.
