Hi guys just replaced water coolent temp sensor and Thermal resistor Board for blowers, Now i have this code that comes up P0141 comes up fault 02 pend 00
then when i scroll i get this 01/02 then next scroll is 02/02 now i know its O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2) but cant find what the other one is, Or does this mean both 02 sensors have got pre cat and post cat.

Thanks for any help

Found out its the 02 sensor just passed the cat, question is now is the o2 sensor the same as the one on exhaust manifold, Thanks
