What should the O2 sensor heater be at?
What should the O2 sensor heater be at?
http://www.autodiagnosticsandpublishi… The Oxygen sensor heater maintains a sensor temperature of about 600 degrees Fahrenheit or 315.5 degrees Celcius. This is the normal operating temperature for the O2 sensor.
Where is the best place to place an oxygen sensor?
In all cases the sensor should be perpendicular to the gas flow, ie. the bung should sit square over the pipe – this ensures adequate but not an excessive amount of gas enters the sensor. We recommend placing the sensor around 1 m (40″) from the closest exhaust valve.
How is the temperature of an oxygen sensor controlled?
The sensor is heated to about 1,200 degrees F (650 degrees C), double the temperature of a basic heated oxygen sensor. Sensor heaters can draw a lot of current, so battery voltage is usually supplied directly to the heaters through a relay and a fuse. The heaters’ ground circuit is controlled by the PCM.
Where are the O2 sensors on my car?
If a vehicle being serviced is not covered in the charts, inspect the exhaust system in the general locations to find the applicable O2 sensors. NOTE: If equipped with dual exhaust systems, there may be up to 4 or 5 O2 sensors in the exhaust system.
How to locate the correct O2 sensor in bank 1?
Bank 1, Bank 2. Oxygen O2 Sensor Location, I show you how to locate the correct O2 sensor. P0131. – YouTube How Compelling Is Your Writing?

How do you know if that oxygen sensor heater is working?
General Motors (GM) calls this Resistance Calculated Oxygen Sensor Heater Temperature (RCOHT). The same principal is used to measure coolant temperature, but in this application the measurements must be extremely fast and infinitely more precise. The heater circuit has a calibration resistor built into the wiring harness or sensor connector.
