Re: What does this combination of symptoms & error codes mean?

Can you read live data with your scanner? If so, it would be interesting to see what the PCM is reading as the coolant temperature. That could implicate the CTS and its circuit.

P0125 - Insufficient Coolant Temp For Closed Loop

P0130 - O2 Circuit (Bank 1, Sensor 1) lean

P0133 - O2 Circuit Slow Response

The 130/133 could be the result of the PCM not achieving closed loop mode and trimming fuel appropriately.
