Generic: Oxygen (A/F) Sensor Heater Control Circuit High (Bank 1 Sensor 1) Nissan: Heated oxygen sensor (HO2S) 1 Bank 1 - heater voltage high What does that mean?This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, ...
While the sensor cools, the sensor resistance is measured by means of a large pull-up resistor and a small pull-up resistor, with the small resistor being switched into the circuit at regular intervals for a short period of time. The use of the small pull-up resistor not only increases ...
It basically means the PCM detected either an excessive current draw, or an open or short in the circuit powering the oxygen sensor's heater circuit. This is in reference to the Heated Oxygen Sensor (2) located rear of catalytic converter (Bank 2)....
PURPOSE:To reduce the heat generation of a resistance and to perform feedback control excellently by shortening the time wherein a voltage for measurement is supplied to the series circuit of the oxygen sensor heater and resistance. CONSTITUTION:A transistor(TR) 14 for power control is turned of...

PURPOSE:To prevent deterioration in a platinum metal medium layer and peeling of a protective layer with gasification of poisoning substance, by increasing a voltage to be applied to a heater for heating sensor elements when operation shifts from a running to idling state. CONSTITUTION:An output fr...
Bad O2 (oxygen) sensor Bad heater circuit in the O2 sensor Wiring or connector to the sensor frayed / broken Blown heater circuit fuse Holes in the exhaust system PCM failure Possible Solutions The most common fix is to replace the oxygen sensor. But that doesn't rule out the possibility ...
