Installed Bosch O2 sensor and got a code 0901 and 0303
I have a 96 Sentra GXE. I went to NAPA auto parts and bought a universal o2 sensor which i didnt intend on buying. I should have check before i got home, I dont like the universal kind. But anyways, I didnt want to drive all the way back so i splice the wire and supposely there suppose to be 3 different color wires. Black, Gray, and white.
But somehow the O2 sensor i got was Black, White, and White. I can not distinguish the gray and white because both looks exactly like white to me. So after i hooked it up, the ECU was throwing 0901 and 0303 so i knew i hooked it up wrong. Anyone has the diagram of which wires is which. I am totally confused by Bosch colors.

0901 is for the front o2 sensor heater circuit.
0303 is for the front o2 sensor signal itself.
I'll have to look up the wiring diagram and compare it from the o2 sensor connector to the sensor side.
ok so i check the bosch website and it says that Black - Signal Wire / theres 2 White - Heater Wires but theres no gray. So i was thinking do i hook the two wires together and just leave out the red wire from the OEM wiring?
napa probably messed up and gave you the wrong one, i work at one, it happens alot

but B14 front O2 sensor is three wires not four wires. Theres only black, white and white wires. so how do i hook it up to my existing OE harness which is Black Red and White?

then its the non heated type sensor... multiple wires are heated sensors.
ya i forgot about that, thank you
