2004 Nissan Maxima Engine overheating

[mycrileest]

I have a 2004 Nissan Maxima and It's overheating, the trouble codes it gave when scanned are p1148 and p1168, do I need to replace the o2 sensons and can they actually be responsbile for the overheating engine, also how many 02 sensors are there on a 2004 Nissan Maxima?

1148 and 1168 are strange codes and it looks like they are typically triggered along with other codes. I'd highly doubt that they are going to be the cause of the overheating, and possibly just a side effect of it. There are only really a few causes of over heating and they can be narrowed down to head gasket issues or cooling. I'd make sure that you coolant is topped off, and I'd do a compression and a leak down test on your engine. Are you having any other issues with the car or has it given you trouble in the past?
