02 SENSOR, CHECK ENGINE LIGHT

1998 Dodge Ram • 187,000 miles

I changed the o2 sensor on downstream. And light is still on, and showing that the o2 sensor on downstream is still bad. Any ideas? I have also changed plugs, wires, & distributor cap & rotor. Truck runs fine, just cant get light off to pass emissions test.

What are the actual trouble code number/s? Might be a problem with wiring circuit? If the code was for the 02 heater circuit, you would have to check that circuit.
