Describe the purpose of having both upstream and downstream oxygen sensors in an exhaust system.

To determine

The purpose of having both upstream and downstream oxygen sensors in an exhaust system.

Explanation

A catalytic converter reduces the emission levels of an engine at the exhaust by storing O2 when the mixture is lean and releasing the stored O2 at times when the mixture is rich. The purpose of having both upstream and downstream oxygen sensors in an exhaust system is to determine whether the mixture is rich or lean. The upstream oxygen sensors are installed before the catalytic converter, whereas downstream oxygen sensors are installed after the catalytic converter...
