Delphi Oxygen Sensor P/N:ES10909
Delphi ES20319 oxygen sensor for the 2001-2003 Chevrolet Malibu V6 3.1L and other vehicles measures oxygen in the exhaust and reports it to the engine computer. This Delphi oxygen sensor is tested and calibrated to OE standards for accurate readings.
A worn oxygen sensor can show up as a check-engine light, a rough idle or lower fuel economy, though each of those can have other causes. Before you replace it, look over the wiring and connector for damage with the engine off and cool; a shop can test the sensor's signal.
Listed for a wide range of Chevrolet, Cadillac, Buick, Oldsmobile, Pontiac and GMC models, it fits the 2001-2005 Chevrolet Impala V6 3.4L, the 2004 Impala V6 3.8L and, as a Blazer oxygen sensor, the 2002-2005 Chevrolet Blazer V6 4.3L. This listing is one sensor, and the 2001-2003 Chevrolet Malibu V6 3.1L takes one.
