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.
