I moved your thread to the Gen 3/4 Camry forum.
P0125 = Insufficient Coolant Temperature For Closed Loop Fuel Control
Could be the thermostat is stuck open, or the coolant temperature sensor has gone bad. Does the temperature gage on the instrument cluster show the temperature is about halfway between hot and cold? If it's running too cold, it's probably the thermostat.
P1135 = Air/Fuel Sensor Heater Circuit Response. (Bank 1 Sensor 1)
That's the sensor in the rear bank's exhaust manifold. Here's a DIY thread showing how to replace it: DIY: 1MZ-FE rear bank air fuel/ O2 senor replacement.
