Delphi ES20119 Oxygen Sensor - Front or Rear

Delphi ES20119 Oxygen Sensor Overview

The Delphi ES20119 is a heated oxygen sensor built for direct-fit emission control service on select Toyota applications. It uses a 4-wire design, square connector shape, and 18 x 1.5 mm thread size to match the specified vehicle locations and restore accurate exhaust oxygen feedback.

Built from Delphi’s OE heritage and supplier experience, this oxygen sensor supports precise air-fuel monitoring for Toyota 4Runner and Toyota Pickup/T100 applications. It is a practical replacement for front or rear positions where the vehicle listing calls for this exact configuration.

• 4-wire design for the listed emission control applications
• Square connector shape for OE-style electrical connection
• 18 x 1.5 mm thread size for the specified mounting point
• Overall length: 230.0
• Package contents include the oxygen sensor and instruction sheet
• Compatible with front and rear positions, depending on vehicle application

Detailed Product Description

Delphi ES20119 is an emission control sensor intended for vehicles that require a heated oxygen sensor with the listed connector and thread specifications. It is engineered for Toyota 4Runner, Toyota Pickup, and Toyota T100 applications where the original sensor location and connector style match the fitment data. This part number, ES20119, is also referenced in cross-application listings for Bosch 13104 and DENSO Auto Parts 234-4154.

For Toyota 4Runner and Toyota Pickup service, this sensor supports accurate exhaust monitoring in both front and rear positions where specified. The OE-focused design reflects Delphi’s long history supplying original equipment components and applying that knowledge to aftermarket replacement parts.

Common Issues This Sensor Can Address

• Faulty oxygen sensor signal causing check engine light concerns
• Incorrect air-fuel feedback affecting engine management
• Emission system faults tied to a worn upstream or downstream sensor
• Rough idle or drivability issues related to inaccurate exhaust readings
• Failed inspection results linked to oxygen sensor performance

Installation Notes and Tips

Confirm the vehicle’s exact year, engine/emissions configuration, and sensor position before installation. Use the application tab to verify whether your Toyota 4Runner, Toyota Pickup, or T100 requires the front or rear location listed for ES20119. Inspect the connector shape, wire count, and thread size against the original sensor before removal.

For best results, compare the old sensor’s routing and mounting depth to the 230.0 overall length before installation. Follow the included instruction sheet and ensure the exhaust threads are clean and properly prepared for the new sensor.

Quality Assurance

Delphi draws on more than a century of OE experience and original-equipment supply knowledge when producing aftermarket emission control parts. That OE-based engineering approach is built into the ES20119 oxygen sensor for the listed Toyota applications.
