I got a code of P1484. I check on the sight it is saying the the cat over heat. Could that be done to the O2 sensor being bad.

Some customers may comment that the Service Engine Soon (SES) or Check Engine light is illuminated. This condition may be intermittent and upon investigation, the technician may find either DTC P0480, P0526, P1481 or P1484 set. This condition may be caused by the cooling fan harness chaffing against the plastic guide it routes through. This contact may damage the insulation of the wires enclosed in that harness. Replace the engine cooling fan harness. Follow this first.
