Description

The Delphi ES20191 is a heated oxygen sensor designed for emission control in select Chevrolet, Geo, and Suzuki vehicles. It features a 4-wire design for reliable signal and heater circuit operation. The sensor has a square connector shape and an 18 x 1.5 mm thread size. The overall length of the sensor is 520.0 mm.

This oxygen sensor is intended to help resolve issues such as rough idling, increased emissions, failed emissions tests, poor fuel economy, engine hesitation, stalling, and check engine light triggers related to faulty oxygen sensors. It is designed as an OE direct replacement, meaning it offers a bolt-on fit without requiring modifications.
