Nicole Schrader, Some times exhaust system are changed with aftermarket parts or modified and sometimes the O2 sensor locations can change or by some eliminated at times. You should have 2 oxygen sensors on the North America 2.0l mazda engines exhaust, up steam sensor 1 bank 1 will be the front sensor located in the exhaust manifold normally or in short pipe between exhaust manifold and catalytic converter. The 2nd sensor down stream O2 sensor bank 1, sensor 2 will be located in the short pipe exiting the converter or in the rear of converter. Links below may help. Good luck.
