★ Top Answer
In a 2004 Chevy Impala, the O2 sensor is positioned past the catalytic converter, within the car's exhaust system. This sensor, roughly the size of a spark plug, extends into the engine exhaust stream to detect oxygen levels. Its main role is to monitor the oxygen level in the exhaust, allowing the engine to adjust and optimize gas combustion for better efficiency. A common issue that triggers the check engine light is a malfunctioning O2 sensor, so it's important to have them checked if the warning light appears.
