Gently probe pin c and d of the oxygen sensor to read the internal resistance. If you have a scan tool with you, you may also use it to test the performance of your upstream o2 sensor.

You Can Check The Heater For Continuity Between Pins 3 & 4 On The Connector.

Begin by carefully inspecting the o2 sensor in question, along with any corresponding wires. To perform this test, you need to run your engine at 2,000 rpm and observe your oxygen sensor voltages. There are no resistance readings taken on a o2 sensor.

If The Resistance Reads Lower Than The Listed Numbers In Your Repair Manual, The Sensor Is Damaged And Requires Replacement.

If your honda accord o2 sensor is still good, you should see between 10 to 40 ω of resistance. If its under the number listed for the vehicle, replace the sensor. Obvious damage to an o2 sensor will warrant replacement, while wiring damage will necessitate repair.

Tools Needed To Perform These Tests:

Turn the dial to the lowest setting in the resistance mode. If it is within this range, the o2 sensor is operating normally and you can stop testing. If the sensor doesn't respond accordingly or takes time to respond, the sensor isn't working properly.

You Can Check The Oxygen Sensor’s Heating Element By Switching The Multimeter On, To ‘Resistance’ Mode.

If you have a scan tool with you, you may also use it to test the performance of your upstream o2 sensor. If it is open or has low resistance, it is probably the sensor. The other two pins are the pins that are used for the signal of the oxygen sensor.

There Are A Variety Of Ways To Test An O2 Sensor.

If its open, then its bad. Remember you are resting the sensor side of the equation, and that you need to turn your multimeter dial to measure resistance ω. A bad oxygen sensor will cause a wide range of symptoms and issues in your car.
