What causes the code for temperature and how do I repair? It also has code for O2 sensor.

Bought used. Just replaced the catalytic converter. It does not have a front Oxygen sensor. How do I clear the high temperature code?

Yes it does have an upstream o2, it has too. What do you mean by front?

Clearing the temp code does nothing as you have done nothing to repair it. If I were you and it was a 128 code, I would start with a thermostat.

The code was a P0125 insufficient temp closed loop. I am not sure what this means? What do you suggest I start with to repair it?

I would start with a thermostat and a flush. In most cases, it resolves it.
