Fault Codes p0131 and p0132

My 2001 wrangler 2.5 liter just indicated fault codes p0131 and p0132, does this indicate the need to replace the upstream o2 sensor to fix the problem ? Already Tried: checked connections and wiring on harness for upstream o2 sensor Answer: Definition: P0131: o2 Sensor Circuit Low Voltage (Bank 1 Sensor 1) P0132: o2 Sensor Circuit High Voltage (Bank 1 Sensor 1) Yes, Replace the upstream O2 Sensor, clear the codes and all should be well once more.
