P0135 1999 Toyota Camry -

Question

The owners manual got lost so I need to know where the circuit fuse for the oxygen
sensor is located can you help?

Answer 1

Hi there,

The only fuse in the system for the bank 1 O2 sensor is the A/F heater fuse in the fuse box under the hood. This should be labeled as such. If the fuse is good, there is also an A/F heater relay in the system as well that could be failing. Otherwise it's likely the bank 1 sensor 1 has failed.
