94 Mazda, O2 Sensor Switch
Q: I have a ‘94 Mazda and it just reached the 80,000 mile mark, and my check engine light just came on. Is my reset screw in the same place as the ‘89 Isuzu? Where is my oxygen sensor located?

A: Your Mazda is similar to the Isuzu in last weeks column. Yes you have to remove the instrument cluster from the dash and reposition the reset screw to turn off the Check Engine Light for another 80,000 miles. But there is a catch with your Mazda. The computer can also turn on the Check Engine Light. If moving the reset screw doesn’t turn off your Check Engine Light you may have a computer telling you there is a system problem. In the early 90’s Mazda was phasing out the use of mileage timers and allowing the computer to determine when service was necessary. As for the location of the oxygen sensor? Look for a part that looks somewhat like a spark plug (it’s the easiest way to describe it) sticking out of the exhaust by the exhaust manifold.
