CEL codes

truck keeps throwing codes po141 and po171. The PCV elbow has been replaced by me but im leaning toward a o2 sensor since po141 is the heater circuit for the sensors. any idea what it is or what sensor it may even be?

start with an o2 sensor...could be an A/F ratio sensor...find somebody with a scan tool thats capable of reading live data and that should be able to pinpoint the sensor
