Delphi ES20324 Oxygen Sensor Overview
The Delphi ES20324 is a heated oxygen sensor built for precise exhaust monitoring in select Toyota and Lexus applications. It uses a 4-wire design with a square connector and 18 x 1.5 mm thread size for direct-fit replacement in front or rear positions, depending on vehicle application.
Backed by Delphi’s OE heritage and more than 100 years of original-equipment experience, this oxygen sensor reflects the engineering knowledge used by major automakers and carried into aftermarket replacement parts.

What It Helps Address
- Check engine light concerns related to oxygen sensor performance
- Incorrect air-fuel ratio readings from a worn sensor
- Slow sensor response during cold starts
- Emissions test failures tied to exhaust feedback issues
- Rough idle or drivability problems caused by inaccurate exhaust data
Installation Notes
Verify the sensor position before ordering, since this part is used in both front and rear locations depending on the vehicle. Match the connector shape, wire count, and thread size to the original sensor, and confirm California Emission System or non-California application details where listed. Use the included instruction sheet during installation and inspect the exhaust bung threads before tightening the sensor.
Quality Assurance
Delphi builds this oxygen sensor using OE-based engineering knowledge developed through long-term supplier experience with major automakers. That background supports consistent fitment, electrical connection, and sensor performance for the listed Toyota and Lexus applications.
