Hi all,
So I have a PCV installed on my z125 and with the o2 optimizer in place my bike spits a code for: P0030 Oxygen Sensor Heater Malfunction: Wiring either open or short. Has anyone had a similar experience with this? The Dynojet people confirmed the o2 optimizer resistance readings are within spec. Any assistance would be appreciated.
