Question

I changed the post cat O2 sensor with denso OEM,x 2. Still get PO141 should look for O2 sensor heater fuse but don't know where it is??

Answer 1

P0141 02 sensor heater circuit malfunction Bank 1 Sensor 2

There is no heater circuit fuse. the power comes from the EFI relay. Bank 1 is where cylinder 1 is located and Sensor 2 is after the catalytic convertor. Make sure the correct 02 sensor is replaced.
