Review on 🌬️ 234-4137 Denso Oxygen Sensor by Tio Kotaki

Yes, functionally both the O2 Sensor and A/F Ratio Sensor are the same, but when tested 180 degrees they are opposite. Regarding this new underflow O2 sensor (234-4137) I did an extensive search to find out the exact resistors needed for the heater circuit to work properly i.e. H. (two black wires). The ohms, that is the resistance in this sensor, should be approximately (6 ohms and 2 amps as current). I checked your new O2 sensor, it reads 15.6 ohms! I really don't know if this is normal or not? But the sensor looks new. I will replace the old O2 sensor, ride for a while and then update my review.
