Appearence is different than original. fits great. I would suggest Heating the flange that holds the 02 sensor with map gas and a plumbers soldering torch. Do not heat the sensor just the flange that holds the sensor. This will speed up removal of the original sensor and save you time and grief

        Hi Jhonny, glad to assist you! This Denso Oxygen Sensor - Direct Fit (Part No. 234-4012) is an exact upstream sensor for your 1998 Chevrolet Tahoe. However, you will need a downstream oxygen sensor for your vehicle. We do have an exact sensor available online for your vehicle and the part number is 234-4018. Please enter your vehicle on our website and search for this part to check the fitment.

    • Q:

      I have a 2000 Silverado 1500 5.3 l with a engine code PO174 which O2 sensor do I need, and how difficult is it ? Do I have to change both ?
      Asked on 12/9/2016 by JASON from Wisconsin

      1 answer

      • CUSTOMER CARE

        A:

        Happy to help, Jason! Basically this engine code PO174 means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). It depends upon the skill level of the person performing the operation. For help with your project, I recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.

        A:

        I'm happy to help, J! You need to inspect the downstream heated oxygen sensor (HO2S) and replace if necessary. Please provide us with the details of your application (including the year, make and model) and I will be happy to provide you with the correct sensor that can be used if available.

    • Q:

      hello, are all 02 sensors the same on my 96 s10 truck w/V6 and just differ in location? i have an after cat code (P0143)
      Asked on 3/12/2016 by joe from fortson, ga

      1 answer

      • CUSTOMER CARE

        A:

        Hi Joe, happy to help you! 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). 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. The Denso Oxygen Sensor - Direct Fit (Part No. 234-4012) is an exact fit for your 1996 Chevrolet S10 with V6 engine. Please enter your vehicle on our website and search for this part to check the fitment.

    • Q:

      I have three oxygen sensors on my truck, is there a way of testing them to find the bad one?
      Asked on 4/27/2014 by Les from Grand Rapids, Michigan

      1 answer

      • CUSTOMER CARE

        A:

        Hi Les, glad to assist you! Start by visually inspecting the wires leading to and from the oxygen Sensor. Ensure that the wires are properly routed away from the exhaust components and that the wires are not damaged. Next, start the car and let it run until the vehicle is warm, which usually takes about five minutes. The oxygen sensors must be about 600 degrees Fahrenheit to provide an accurate reading. This will cause the engine to become very hot, so be careful. Connect the backprobe to the oxygen sensor's signal wire. Be very careful when using the backprobe, because the plastic connectors are often very brittle and can break easily. Connect the positive lead from the digital voltmeter to the backprobe. Connect the negative lead from the digital voltmeter to a good solid ground point on the chassis of the vehicle. Turn the voltmeter on and set it to the 1 volt scale. The voltage of the oxygen Sensor will fluctuate between 100 and 1,000 millivolts, which is 0.1 and 1.0 volts, so having a quality volt meter is important. Turn the vehicle back on and check the reading on the voltmeter. The reading should fluctuate rapidly. If the reading stays at around 0.5 volts, ensure that the vehicle is fully warmed up. If the vehicle is warm and the oxygen Sensor reading does not change, then there is a problem with the oxygen Sensor and you can stop the test. Next, create a vacuum leak to ensure that the oxygen sensor responds properly to a lean air-fuel mixture. Most vehicles have a vacuum port on the top of the engine, which can be opened up to create a vacuum leak. Creating a vacuum leak should cause the voltage of the oxygen Sensor to drop below .1 volts and then rise above .5 volts when the leak is subsequently plugged. If your vehicle does not have a vacuum port or if creating a vacuum leak causes the vehicle to stall, you can preform a propane enrichment test. This is done by adding some propane gas to the air intake, which should cause the voltage of the oxygen Sensor to quickly rise. As an alternative to a propane enrichment test, you can also slightly close the choke, which should cause the voltage of the oxygen Sensor to quickly rise. If during steps 8 to 10 the voltage does not change or does not change in the expected manner, then the oxygen sensor is bad and should be replaced.
