Delphi Oxygen Sensor P/N:ES20181
Delphi ES20073 rear oxygen sensor for the 1998-2000 Chevrolet Tracker 4-cylinder 1.6L, the 1999-2001 Tracker 4-cylinder 2.0L and other vehicles senses the oxygen in the exhaust and reports it to the engine computer. Like every Delphi oxygen sensor, it is built to Delphi's OE standards.
A worn oxygen sensor can show up as a check engine light, rough running or poorer fuel economy. Exhaust leaks and damaged wiring can also set an oxygen sensor fault code, so with the engine off and cool, look over the connector and wire for damage before you replace the sensor.
The 1998-2000 Chevrolet Tracker 4-cylinder 1.6L, the 1999-2001 Tracker 4-cylinder 2.0L, the 1999-2000 Suzuki Vitara 4-cylinder 1.6L or 2.0L and the 1996-1998 Suzuki Sidekick 4-cylinder 1.6L all fit this sensor at one per vehicle, and so do other vehicles. This listing is a single sensor. Open the "Vehicles it fits" section to check your exact model and engine.
