I really appreciate the order on line feature and then pick up in the store. By ordering on line, it allows me to peruse the parts I buy to get the exact parts I want. Of course, the on line ordering discount doesn't hurt either.

I also appreciate the always available live chat feature, so that all of my questions get answered by someone who if not totally knowledgeable, finds the answer to my questions.

I'm also lucky, in that I have a mechanic that allows me to buy my own parts and just charges me labor. I'm pretty picky about the parts I use. Mostly AC Delco for anything electrical (I have a 1998 Bravada) and MOOG for suspension and steering parts.

I also like the fact that ADVANCE seems to have high quality name brand parts available all across the parts spectrum. There are a couple of other places I turn for hard to find or obscure parts, but I ALWAYS check out ADVANCE first!

Surprised by Bosch

I was surprised as my shop told me one of the sensors was defective. Luckily I was able to exchange it at your store while they had the car. All is well now.

Olds Bravada had code p0154, too little change on Bank2, O2Sensor1. Ten minute replacement, and the problem was solved on the next startup.

The last sensor is located after the catalytic converter called Downstream sensor. The Bosch Premium Oxygen Sensor - Part No. 15703 is interchangeable.

                    I'm happy to help, Joe! Bank 1 generally indicates the driver's side or front depending upon the mounting of the engine (front wheel drive or rear wheel drive). To determine the correct fitment of the part please provide your engine size as well as the sensor number that was read from the code. Sensor 1 is upstream (before the catalytic converter) and Sensor 2 is downstream (after the catalytic converter).

                  Asked on 11/4/2013 by Dave from West Carrollton Ohio

                  1 answer

                  • CUSTOMER CARE

                    A:

                    Hi Dave, the 1998 Chevrolet Blazer has three oxygen sensors. Two are located up on the front Y-pipe bolted to the V-6 engine's manifold. These two sensors detect the fuel-to-air mix in the exhaust and transmit that information to the powertrain control module. From there, the powertrain control module makes adjustments to achieve the lowest emissions possible while still running properly. The third oxygen sensor is located after the catalytic converter. This sensor's job is to monitor the efficiency of the catalytic converter. I would recommend that you replace your sensor in pairs. For instance, if you replace the upstream left sensor, you should also replace the upstream right. However, on most vehicles produced since 1996, replacing one sensor (especially the front engine monitoring sensor) may cause the ECU to set a code for the other sensors. This is because the newer sensor switching activity is much faster than that of the older sensors.
