Where are the oxygen sensors located on a 1996 Chevy Corsica?

The 1996 Chevy Corsica has two oxygen sensors.

1. The first oxygen sensor is located in the exhaust manifold.

- This sensor measures the amount of oxygen in the exhaust gas before it enters the catalytic converter.

- The oxygen sensor signal is used by the engine control module (ECM) to adjust the air/fuel mixture.

2. The second oxygen sensor is located in the exhaust pipe after the catalytic converter.

- This sensor measures the amount of oxygen in the exhaust gas after it has passed through the catalytic converter.

- The oxygen sensor signal is used by the ECM to monitor the efficiency of the catalytic converter.
