Question about 2001 Toyota Camry
P1135: A/F Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
Your first O2 sensor is not getting heated either because the wiring to the sensor is bad or the heater inside the sensor is bad. If you have a four cylinder this would be the only O2 sensor you have before the catalyst. I would just replace the sensor, clear the code, and see if it comes back.
