        While replacing the catalytic converter, we decided to change out both this product (upstream) and the "downstream" O2 sensors.

        Part worked - check engine light off

        from Berea, KY

        Verified Buyer

        Comments about Bosch Oxygen Sensor:

        The mechanic put the part in within ten minutes and the check engine light went out. My old one went bad after changing motors and the mechanic said it was probably from exposing it to regular air for a few days while the engine was being installed. It works...has worked for three weeks now.

                  Comments about Bosch Oxygen Sensor:

                  Purchased this for a 2002 Ford Ranger XLT extended cab with no engine modifications and unfortunately, it did not fit. This was for a pre-cat or upstream replacement. Was replacing both sides and the length of the plug-ins on these Bosch did not fit. They were about 6 inches too short. All the information said these were the right parts but they were not. Returned them to Advance Auto and got an "offbrand" and they fit perfect. [...] Never have a problem returning parts when I screw up and purchase the wrong thing.

                      A:

                      Hi Larry, it's actually a good question! There are four oxygen sensors on your truck. The two upstream oxygen sensors are located before the catalytic converter, downstream is after. The upstream sensors affect how the engine runs, the downstream sensor only tells if the catalytic converter is going bad. On your truck both sensors are the same part number #15664.

                      A:

                      Bank 1 is the passenger side of the engine and the Sensor 1 is in the exhaust close to the engine before the exhaust goes through the catalytic converter. Bank 2 should indicate driver side, and sensor 1 should be the sensor closest to the front of the car, upstream of the catalytic converter.
