Dodge Grand Wheelchair

Dodge Grand Wheelchair
i own a 2005 dodge grand caravan sxt 3 point 8 liter motor with a wheelchair ramp because im in a wheelchair?

ive had the o2 sensors replaced twice,the codes keep reading bad sensors,so i had it put on a diagnostic machine and it said there was a wiring problem or computer going bad,does anyone have any idea what might be causing my engine light to stay on after the diagnostic machine tested it,the engine runs fine no problems with that.its just the engine light stays on what could be causing this

A bad cat. A piece of tape could cover up the light.
