P1155 Toyota -

P1155 Toyota: can the code P1155 throw a code P1150 or vice versa?

Vehicle: 2000 Toyota Avalon 6 cyl

Hi there,

These codes are for bank 1 and bank 2 O2 sensors, it's unlikely that one would cause the other. If you have both codes, check the wiring harness and also make sure the engine is performing properly. A poorly running engine could cause failure codes for both the front O2 sensors.
