Hey Versa owners! wonder if yall hate ur car as much as i do mine...anyway i got a SES light and went to advanced and recieved an upstream o2 sensor code...replaced o2 sensor did ECM steps to clear code...whaddya know the SES came back on...went to auto zone and got four codes...P0031- 02 sensor P0113- Intake Air Temp Circuit P1148- Closed Loop Control (Bank 1) and P0102- BARO/MAF/VAF this i believe could be the Vaccuum hose, throttle body intake tube loose, Barometer/Manifold Absolute Pressure defective, or Vane Air Flow/Mass Air Flow sensor...(guessing its the sensor) They all seem to be connected but i dont know where to start...the o2 sensor fuse? replace the MAF/IAT sensor? im just lost they are all connected (i think) and im not sure where to start besides where i left off...o2 sensor is replaced...could all these problems be because the o2 sensor wires are matched incorrectly...o woe is me...help!
