What is the solution for the error message po137 o2 sensor circuit low voltage bank 1 sensor 2?

PO137 (Sensor Circuit low voltage Bank 1 Sensor 2) This is the O2 sensor behind the Catalytic Converter on the #1 spark plug side. Check the wiring on that sensor before proceeding. More than likely replacing that sensor will solve the problem especially if you have over 75,000 miles on the vehicle. But there is no guarantee that will fix it.

Where is the the o2 sensor circuit high voltage bank 1 sensor 2 located on a 1999 jeep wrangler 2.5l?
Sensor 2 is after the catalytic converter.
99 gmc 5.3 engine is there a fused circuit for the knock sensor?
the knock sensor is not a fused circuit, it consists of a wire from the sensor to the pcm or ecm, when the motor knocks(misfires), the sensor( a piezo electric device, like the ignitor for a grill)outputs voltage into the pcm, its a closed circuit and not much to it.
What is a function of a resistor in a fire alarm circuit?
A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit. The resistor has a calibrated and known voltage drop and current while the circuit is "normal". If there is a short-circuit, or an open-circuit, the voltage and current will change and trigger the trouble alarm.
