Where is the O2 sensor on a Honda Accord?
This test is for the 1995-2002 Honda Accord, but the Accord O2 sensor wire colors will vary depending on your car. The wires you will be testing are on the ENGINE harness side, not the sensor. Insert your Honda Accord ignition key and turn your ignition to the “ON” position. This sends power to your engine sensors.
What are the wires on an oxygen sensor?
Identify the different wires. One of the wires on the sensor is the ground wire, the other wire is the signal wire, and the remaining two wires are the heater circuit wires. All of these wires are coded with a color. Depending on the brand of the sensor the colors will vary.
How do you check the oxygen level in a car?
Warm up the engine to obtain an accurate reading. Locate the oxygen sensor and wiring harness; the O2 sensor is underneath the vehicle where the transmission meets the engine. Follow the wire back from the sensor to the wiring harness connector. Use the voltmeter to hook up to the signal wire or probe directly into the harness connector.
How can I bypass the O2 sensor in my car?
Plug in the dummy oxygen/o2 sensor by rotating it clockwise. Insert it into the exhaust system and connect it to the electrical wiring. You can now lower the car onto the ground, but wait, we’re not done yet! Once your vehicle is safely lowered to the ground, you will need to start the engine.
Where is the location of oxygen sensor?
The oxygen sensor, also known as a lambda sensor, is located in the exhaust manifold of the car. It measures the amount of oxygen in the gases leaving your car through the exhaust.
Where is the upstream oxygen sensor located?
The upstream oxygen sensor is located right before the catalytic converter. It is installed in the exhaust manifold or in the exhaust pipe near the engine. The role of the upstream oxygen sensor is to optimize the air-fuel ratio entering the engine. There can be one or two oxygen sensors depending on the number of cylinders.
Where are the oxygen sensors located on the engine?
Oxygen sensors O2 sensors will always be located in the exhaust system. Their function is to sense how much oxygen remains in the exhaust that is flowing out of the engine, and report that information to the vehicle’s engine control computer.
Where is the heated oxygen sensor located?
The Heated Oxygen Sensors (HO2S) sensors are located in the exhaust system. One sensor is located up at the exhaust manifold(s) and the other sensor is located down at the catalytic converter.
How do you wire up an O2 sensor?
This should be done first. These wires serve to heat up the O2 sensor to bring it up to operating temperature via a resistance-based heating element. To test, set the multimeter to resistance mode and use it to probe and figure out which wires register a resistance (usually 4-6 Ω).

How to diagnose O2 sensor heater circuit failure?
The modified test harness with the light will give you easy access to the circuit. Remember, the engine needs to be running at this point. If the voltage is close to zero on the positive heater wire, then locate the open circuit in the power wire back to the fuse. Again, it may have a relay in the circuit as well.
