Single prong plugs/ p0135

[viper224]

Hey guys,
Last week I did a bunch of work to my car including valve cover gaskets, plugs, sway bar bushings, strut mounts and the struts. All went smoothly till I turned the car on and got a p0135 o2 heater circuit code. This is the bank one sensor one o2 and I had thought I just forgot to plug it back in from removing the manifold. It was in fact plugged in, just real confused why it suddenly went bad when things were apart for the day. I do know I used single prong platinums which I found out later I shouldn't have. Could this have fouled my heated o2 or is this all coincidence? Also anyone know If having these single prongs will do any damage or cause any problems? I'd like to not change those rears if I don't have to. Or even I just thought, maybe those caused the code. I just don't know I would love some input. Thanks!

The heater code is very specific to the heater on the sensor. Other codes are used if the sensor itself is not working OK. The plugs will wear out faster but should not cause an O2 sensor issue.

Are any sensor wire damaged? If you can reset the trouble codes and determine if it pops back up again.

Thanks so much for the input, thats a relief I wont have to change the spark plugs again. I very well could have damaged the sensor wires when pulling up on the wire harness to get the valve cover off. That rear o2 was connected for a minute while I was pulling. I did a resistance test to see if I was showing any resistance across the black wires, showed and open circuit. Maybe one of the wires got yanked out. I'll pull it out when I get a chance and check it out. Would sound a lot better than a new o2.
