Make sure that the cooling fan is coming on when the engine reaches elevated
temperature. Monitor the gauge if the vehicle has one and make sure the
temperature rises linearly and stop before it redlines if the fan does not
kick in. If the vehicle has AC, then turn it on and the fan(s) should start
automatically along with the AC compressor.

If the fan does not come on, then it is either a blown fuse, a defective
coolant temperature sensor, a bad fan relay, bad wiring/connectors, or a
defective fan. You need to trouble shoot from there based on what you see
or take it to someone who can do it for you.

Good luck.

P0133: The response time for oxygen sensor 1 in bank 1 was too slow
during testing. Easy enough to replace and figure out, I believe.

Might be easy enough to replace but is that the root cause? Dont know
how many miles you have on your car but it might also be due for a tune
up.
