I suspect these are related but they are not related systems. So, the best way to figure this out is to pick one of the codes and solve it and if it doesn't solve the others then we can move onto them.

I would suggest starting with one of the P codes as these are going to be the ones that turn your light on.

I am attaching the testing below but here is a guide that will help with checking the wiring as it asks:

More than likely we have a wiring issue that is causing these codes so I would start with the o2 sensor code and then move onto the cooling system code.

Please run through the testing below and let us know what you find, and we can go from there.

Thanks
