Do NOT replace the Oxygen Sensor!! P0171 means that the system is ACCURATELY detecting a lean air/fuel ratio. If it was an Oxygen Sensor problem, there are many other codes for that. go to this article that I wrote about tracing down a P0171 code. it has helped several people. http://repairpal.com/OBD-Code-P0171-and-P0174
