Bosch Oxygen Sensor P/N:16643
Bosch 16451 oxygen sensor for the 2012-2016 GMC Acadia V6 3.6L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. This Bosch O2 sensor is a heated, narrow-band, switching-type unit.
A check engine light, weaker fuel economy or a rough idle can mean the sensor is worn. Before you replace it, rule out an exhaust leak, a damaged connector or another fault that sets the same code.
