    Feature:

     

    • Corrosion-resistant stainless steel construction
    • In easier installation and resistance to high temperatures, vibration damage and wire corrosion, which protects signal accuracy and longevity.
    • Industry's fastest light-off times to reduce cold-start emissions and improved fuel economy over aging sensor
    • Unique sensor coatings protect elements from premature failure and are validated for lifetime operation with E85 and other alcohol-based fuels.

     

    Oxygen Sensor Q & A

    1. How many oxygen sensors are on today's engines?
    It depends on the model year and type of engine. On most four and straight six cylinder engines, there is usually a single oxygen sensor mounted in the exhaust manifold. On V6, V8 and V10 engines, there are usually two oxygen sensors, one in each exhaust manifold. This allows the computer to monitor the air/fuel mixture from each bank of cylinders.
    On later model vehicles with OBD II (some 1993 and '94 models, and all 1995 and newer models), one or two additional oxygen sensors are also mounted in or behind the catalytic converter to monitor converter efficiency. These are referred to as the downstream O2 sensors, and thee will be one for each converter if the engine has dual exhausts with separate converters.

     

    2.Where is Oxygen Sensor Locations?

    When troubleshooting oxygen sensor problems with a scan tool, you may find a diagnostic trouble code for one of the O2 sensors. The code displayed on your scan tool will indicate the type of fault, and identify one of the oxygen sensors by its position in the exhaust system.

    The oxygen sensor's location will be identified by position (sensor 1, sensor 2 or sensor 3), and by cylinder bank (bank 1 or bank 2).
    Most late model engines have multiple oxygen sensors, so which one is sensor 1, 2 or 3, and how do you know which cylinder bank is 1 or 2?

    On straight four and six cylinder engines, there is only one bank of cylinders. So all of the oxygen sensors will be bank 1. The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 sensor located in or behind the catalytic converter will be Sensor 2.

    The location of the number one cylinder on import engines will vary depending on the year/make/model. One way to find number one cylinder so you can identify bank 1 is to look at the ignition system.  If it has a distributorless ignition system (DIS) or a coil-on-plug (COP) ignition, the plug wires or coils may have lettering or marking indicating the cylinder numbers.

    If a V6, V8 or V10 engine has dual exhausts with dual converters, the downstream O2 sensors would be labeled Bank 1, Sensor 2 and Bank 2, Sensor 2. Or, the downstream oxygen sensor might be labeled Bank 1 Sensor 3 if the engine has two upstream oxygen sensors in the exhaust manifold (some do to more accurately monitor emissions).

     

    3.how to replace an oxygen sensor

    Step 1. Locate the oxygen sensor on your vehicle by looking for a part that looks like a spark plug that sticks out from the exhaust pipe. It will have an electrical connection attached to it.

    Step 2. Disconnect the electrical connection on the oxygen sensor. Use a flat tip screwdriver to push in the tabs and pull the connection apart.

    Step 3. Unscrew the oxygen sensor off the exhaust pipe using either an open-end wrench or a special socket made to remove it. The majority of oxygen sensors will take an SAE 7⁄8 inch (2.2 cm) wrench.

    Step 4. Compare your new oxygen sensor to the old one. If the new one did not come with an electrical connection, but just with the wires stubbed out, you need to do a little work.

       ?Cut off the old connector from the bad oxygen sensor, strip the wires and solder the wires to the new oxygen sensor. You can also use butt connectors.

       ?Use heat sensitive shrink tape to seal the connections.

       ?Follow manufacturer's instructions to know which wires to tie together.

    Step 5. Reverse the steps used in removing the oxygen sensor and install the new part. Add a small amount of anti-seize to the threads of the new sensor. Screw it in place clockwise and snug it down with the socket or open-end wrench. Do not over tighten the sensor as you might strip the threads.

    Step 6. Plug the electrical connections back in.

    Step 7. Turn on the ignition key, but do not start your vehicle. Use the diagnostic scanner/reader to clear the code from the vehicle's computer.

    Step 8. Start the car. You should notice an immediate improvement.

    Oxygen Sensor Q & A

    1. How many oxygen sensors are on today's engines?
    It depends on the model year and type of engine. On most four and straight six cylinder engines, there is usually a single oxygen sensor mounted in the exhaust manifold. On V6, V8 and V10 engines, there are usually two oxygen sensors, one in each exhaust manifold. This allows the computer to monitor the air/fuel mixture from each bank of cylinders.
    On later model vehicles with OBD II (some 1993 and '94 models, and all 1995 and newer models), one or two additional oxygen sensors are also mounted in or behind the catalytic converter to monitor converter efficiency. These are referred to as the downstream O2 sensors, and thee will be one for each converter if the engine has dual exhausts with separate converters.

     

    2.Where is Oxygen Sensor Locations?

    When troubleshooting oxygen sensor problems with a scan tool, you may find a diagnostic trouble code for one of the O2 sensors. The code displayed on your scan tool will indicate the type of fault, and identify one of the oxygen sensors by its position in the exhaust system.

    The oxygen sensor's location will be identified by position (sensor 1, sensor 2 or sensor 3), and by cylinder bank (bank 1 or bank 2).
    Most late model engines have multiple oxygen sensors, so which one is sensor 1, 2 or 3, and how do you know which cylinder bank is 1 or 2?

    On straight four and six cylinder engines, there is only one bank of cylinders. So all of the oxygen sensors will be bank 1. The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 sensor located in or behind the catalytic converter will be Sensor 2.

    The location of the number one cylinder on import engines will vary depending on the year/make/model. One way to find number one cylinder so you can identify bank 1 is to look at the ignition system.  If it has a distributorless ignition system (DIS) or a coil-on-plug (COP) ignition, the plug wires or coils may have lettering or marking indicating the cylinder numbers.

    If a V6, V8 or V10 engine has dual exhausts with dual converters, the downstream O2 sensors would be labeled Bank 1, Sensor 2 and Bank 2, Sensor 2. Or, the downstream oxygen sensor might be labeled Bank 1 Sensor 3 if the engine has two upstream oxygen sensors in the exhaust manifold (some do to more accurately monitor emissions).

     

    3.how to replace an oxygen sensor

    Step 1. Locate the oxygen sensor on your vehicle by looking for a part that looks like a spark plug that sticks out from the exhaust pipe. It will have an electrical connection attached to it.

    Step 2. Disconnect the electrical connection on the oxygen sensor. Use a flat tip screwdriver to push in the tabs and pull the connection apart.

    Step 3. Unscrew the oxygen sensor off the exhaust pipe using either an open-end wrench or a special socket made to remove it. The majority of oxygen sensors will take an SAE 7⁄8 inch (2.2 cm) wrench.

    Step 4. Compare your new oxygen sensor to the old one. If the new one did not come with an electrical connection, but just with the wires stubbed out, you need to do a little work.

       ?Cut off the old connector from the bad oxygen sensor, strip the wires and solder the wires to the new oxygen sensor. You can also use butt connectors.

       ?Use heat sensitive shrink tape to seal the connections.

       ?Follow manufacturer's instructions to know which wires to tie together.

    Step 5. Reverse the steps used in removing the oxygen sensor and install the new part. Add a small amount of anti-seize to the threads of the new sensor. Screw it in place clockwise and snug it down with the socket or open-end wrench. Do not over tighten the sensor as you might strip the threads.

    Step 6. Plug the electrical connections back in.

    Step 7. Turn on the ignition key, but do not start your vehicle. Use the diagnostic scanner/reader to clear the code from the vehicle's computer.

    Step 8. Start the car. You should notice an immediate improvement.
