            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.

        • Q:

          My 99 Suburban sometimes starts hard. this did not begin untill about the same time we noticed the trans was kicking in and out of high gear. The ODB shows no trouble codes.
          Coud these problems be related to a faulty oxygen or speed sensor?
          We also have a 7yr. old battery under the hood. Could this be causing electrical problems?

            I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not solve or be the problem.

            A:

            You truck should actually have 4 oxygen sensors. Two up stream (pre-cat) and two down stream (post-cat). The number you need depends on how many are bad and which exact ones are bad.
