Can you wire two oxygen sensors to the same wires to get rid of my check engine light?

NO, you cannot do this, this will compound your problem and eventually damage the engine and/or catalytic converter to the point that they/it must be replaced, all three failures are very expensive repairs. The faulty O2 sensor must be identified and replaced. There are 4 set-ups: Single sensor; Dual "upstream" <both sensors are pre-cat>; Dual upstream/downstream <one sensor is pre-cat, one sensor is post-cat> and Quad sensor <two sensors are pre-cat, two sensors are post-cat>. The upstream controls the fuel mixture and the downstream monitors the catalytic converter. BANK 1 is always the number 1 spark plug side and SENSOR 1 is always upstream. Once the fault is corrected the ECM must be cleared with a scanner to shut off the light.

How can you reset your o2 sensors on your 2001 Ford 4x4?
You can not reset your oxygen sensors. You can only replace them. To reset the check engine light you will have to get that done by a repair shop with a computor. If replacing the sensors does not repair the problem then check for a vacuum leak.
How do you check the oxygen sensor on 97 Dodge 318?
Oxygen sensors either work or they don't. If they don't, the check engine light will come on and indicate an oxygen sensor problem. If they're fine, none of that will happen.
I have a 1995 Ford Taurus that runs fine but every time you hit a big bump the check engine light comes on for a few minutes then goes out what is happening?
If the check engine light is coming on periodically when hitting a bump in a 1995 Ford Taurus, perhaps a sensor is loose. Check both the oxygen sensors and the speed sensors on the transmission. Also check all sensors in the engine to make sure they are tight.
What are the symptoms of faulty oxygen sensors on a 2006 Chevy Express van?
The check engine light would illuminate and the code(s) would point to one or more of the O2 sensors.
What would cause the check engine light to stay on in your 1996 Nissan Altima GXE?
