Comments about Denso Oxygen Sensor - Direct Fit:

Janet got the loaner tool set that I needed. Sold me the right o2 sensor and even looked it up in the service manual so I knew where to find it on the car. I buy everything I need at my local store.

      Installed in a '06 Envoy SLT 4.2L I6. Looked like an exact replacement. I read online that Denso makes these sensors for AC Delco. It sure looked exactly the same as the original. Works great so far,

                  Hi Steve, good question! The upstream sensor refers to the location of the oxygen sensors relative to the engine. It will be the closest to the engine, and are used to sense the air/fuel ratio and tell the computer how much fuel to inject.
