What do you need to replace O2 sensor on Miata?
Be sure to confirm the issue isn’t related to exhaust leaks, the exhaust gas recirculation (EGR) system, vacuum leaks, the MAF sensor, etc prior to replacing the O2 sensor. The only tools required for this job are a decently long socket extension, a 3/8″ socket wrench, and one of these O2 sensor sockets.
When to eliminate the rear O2 sensor in a car?
When people modify their cars to gain horsepower, the O2 sensor usually tells the computer that the vehicle is outside regulation and the check engine light comes on. Some people eliminate the rear O2 sensor located directly in front of the catalytic converter to overcome the check engine light.
Where is the cam angle sensor on a Miata?
It connects to the wiring harness near the cam angle sensor on the back of the motor’s head. It has a little clip you push in, then pull it out. It can stick fairly tight if it has never been removed, but shouldn’t be a big deal. Once the wiring is out, you can feed it down to where the sensor itself is.

What causes a check engine light on a Miata?
This is done by opening and closing an EGR valve. The Miata’s computer calls for the valve to open and close based on a number of factors. If the computer senses that this is not being done properly (valve stuck open or closed or lines plugged), then the CEL is turned on.
