NGK O2 SENSORS 25709 ntk for the 2009-2011 Chevrolet Aveo 4-cylinder 1.6L and other vehicles senses oxygen in the exhaust and feeds that reading to the ECU. That closed-loop feedback helps the ECU control the air-fuel ratio and helps the OBDII system flag fuel delivery or catalytic converter efficiency problems.
A check engine light, rough running or a drop in fuel economy can mean an oxygen sensor is worn. Before you replace it, rule out exhaust leaks, damaged wiring or connectors and fuel-delivery faults that can also set an oxygen sensor code.
The 2009-2011 Chevrolet Aveo 4-cylinder 1.6L, the 2009-2011 Chevrolet Aveo5 4-cylinder 1.6L and the 2009-2010 Pontiac G3 4-cylinder 1.6L take this sensor, and so do other vehicles. If your car is not named here, find it in the "Vehicles it fits" section.
