1998 Dodge Neon 4 cyl Automatic

I have a 98 dodge neon and I recently had the check engine light come on and well I got it checked out and it was misfiring and the sparkplugs and the O2 sensor came up. So I replaced everything I need for the misfiring. New spark plugs, new cords and a new new sensor and I had them clear the system well I drove it for a couple of days and than it came back on and so I went to get it check and they gave me the code p0138 saying that the in out voltage from oxygen sensor 2 in bank1 is too high for current operating conditions. What do I need to do to fix that?

Did you replace the O2 Sensor closest to the engine? If so that was Sensor 1 Bank 1 and is located in Manifold. There are 2 O2 Sensors you should replace the second one which is located at the Rear of the Catalytic Converter.

Would that explain why the input voltage is too high?

Ok, Looked up code you have posted
P0138 - O2 Sensor Bank1 Sensor2 Shorted to Voltage.

Check Connection and wiring for chaffing.
