Did not fit.

My 2000 GMC Sonoma with the 2.2 4-cyl. has a two-wire 02 sensor. This only has one. Web site says it's compatible, but I don't see how.

                  Comments about Bosch Oxygen Sensor:

                  This oxygen sensor was for an OBD2 Saturn. Typically OBD2 sensors are four wire heated but in this application it happens to be a single wire, unheated sensor. Since the customer is financially struggling we decided we could roll the dice with a universal sensor. Scan data after replacement indicated good switching rate and the readiness monitor passed so customer was able to get through emission test. I use Bosch sensors routinely at work and have had very few problems with them over the years.

                  Comments about Bosch Oxygen Sensor:

                  I purchased this oxygen sensor last week but have not installed it yet, for two reasons: 1) I am waiting to see that my rebate submission for this item is approved first, and 2) the old oxygen sensor is difficult to remove. It probably doesn't help matters that the old unit is the original that came with the 28-year-old vehicle. I will have to see if I can find a suitable wrench able to get into the very confined area and do the job. So unfortunately, I am unable to comment on the new oxygen sensor's performance at this time. It does look nearly identical to the OEM unit, though.

                        A:

                        The oxygen sensor is located in the Catalytic converter. Most late model cars have two sensors. There will be one at the front of the catalytic converter, and one at the rear. You should be able to see wires going to the catalytic converter. In most cases it is recommended that all oxygen sensors be replaced at the same time to prevent incorrect readings to your engine computer and a constant check engine light being on.
