Maybe go back a week later, whenever you have the free time, and see if there is a code again. The O2 heater is used to get the O2 sensor to reach operating temperature as quickly as possible as the engine runs most efficient when it's in closed loop. Also sometimes there is a pcm reflash for the pro. It technically stands for: The purpose of the heated element in the oxygen sensor is to quickly bring it up to normal operating temperature after your Accord has been started.

I think a good starting point is to describe how an O2 sensor works. For example say the engine is running rich, there is less oxygen in the exhaust stream and still the same amount of oxygen in the outside air, this difference causes the O2 to produce a high voltage, typically near 1. The code is triggered when the sensor is taking too long to warm up. To test the ground side of the circuit, connect the red multimeter lead to the battery positive terminal and the black lead to ground. Bank 2 is the opposite side of the engine.

Then, connect your meter leads to both of the heater circuit pins on the sensor side of the connector. The O2 sensors in the catalytic converter or behind the catalytic converter secondary O2 sensors are there to monitor catalytic converter efficiency, we'll cover those in another article but if one of those has a heater failure the testing is exactly the same as for a primary O2 sensor. If you have anything that you would like to add, please feel free to leave a comment below. It is used to determine the concentration of oxygen in the exhaust gas.

Modern vehicles use both an upstream and downstream oxygen sensor. Now that we know what wires we're dealing with we can do a simple test to confirm that indeed the sensor heater is faulty.
