Upstream And Downstream O2 Sensors On My Car Listed Above I Have Hi, the terms upstream and downstream simply refer to the location of the catalytic converter and where the sensors sit in relationship to it. upstream means before or above the converter. downstream means below or after. in this case, the downstream will be slightly ahead of the catalytic converter under the vehicle. i attached a pic below. Most vehicles have an upstream and downstream oxygen (o2) sensor that measures the oxygen content in the exhaust. the upstream o2 sensor is found before the catalytic converter, while the downstream o2 sensor is located after the catalytic converter. the upstream o2 sensor helps identify the vehicle’s fuel trim, which helps the engine.
юааupstreamюаб Vs юааdownstreamюаб юааo2юаб юааsensorюаб Whatтащs The Difference In The The best thing to test the o2 sensor is using a scanner with the “data stream” function. this allows you to see how fast the voltages will go up and down. open the main menu on your scanner, and select “diagnose”. in the “diagnostic menu”, tap the “data stream” icon. (the function name on scanner might be a bit different. However, some vehicles may have multiple upstream or downstream sensors depending on their exhaust system design. replacement. if you suspect that your o2 sensor is faulty, it is important to know which sensor needs to be replaced. upstream and downstream sensors have different part numbers and are not interchangeable. The major oxygen sensors (upstream) will break first since the rubbish streams and burns across them (gas), making it become a bad oxygen sensor soon. how much do upstream and downstream o2 sensors cost? the average cost of the upstream oxygen o2 sensor will vary according to your car type. however, the average price for this component is $35. Find bank 1 or bank 2 on your car. you’ll need to determine bank 1 vs. bank 2 to find the upstream and downstream o2 sensors. you can tell which bank is which by looking at the firing order of your vehicle’s engine. the bank that includes cylinder 1 is bank 1, and the other bank will be bank 2, regardless if if it includes cylinder 2 or not.

But the average cost of this part is $35. upstream oxygen sensors can cost between $15 and $70. while the part itself is not super expensive, the installation usually costs more than the sensor. an upstream sensor replacement usually costs $150 to $200, including all labor and parts. Upstream oxygen sensors can be stuffed into tight places that might be tough to reach with a socket and driver. occasionally, exposure to road salt and heat can corrode both upstream and downstream sensors and make them a challenge to break free. if you pay a professional to replace the sensor for you, the cost is generally between $350 and $400.
