Delphi ES20182 Oxygen Sensor

Delphi ES20182 Oxygen Sensor Overview

The Delphi ES20182 is a heated oxygen sensor built with OE heritage and supplier experience developed through work with major automakers. It is a front-position sensor with a 4-wire design, square connector shape, and 18 x 1.5 mm thread size for direct replacement service on select Toyota applications.

Compatible With 1988-1989 Toyota 4Runner and 1988 Toyota Pickup, this oxygen sensor supports accurate exhaust feedback for vehicles that rely on a front sensor location. The Delphi ES20182 is built for drivers and technicians looking for a replacement that matches the original application details.

Key Features

• Heated oxygen sensor design for faster operating readiness
• 4-wire configuration
• Square connector shape
• 18 x 1.5 mm thread size
• Overall length: 835.0
• Front position application

Application Details

This part cross-references DENSO Auto Parts 234-4152 for the same application. It also cross-references Bosch 13281 for select OE-style replacement needs. Use Delphi ES20182 when servicing the front oxygen sensor on 1988-1989 Toyota 4Runner or 1988 Toyota Pickup models listed in the fitment data.

Delphi builds this sensor using OE-focused engineering knowledge gained from supplying original equipment to global automakers. That background is reflected in the sensor’s connector style, thread specification, wire count, and heated design, all of which matter when replacing a front oxygen sensor on a Toyota 4Runner or Toyota Pickup.

What This Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect exhaust feedback from a worn front sensor
• Rough idle or drivability issues tied to sensor signal degradation
• Fuel mixture control problems caused by aging sensor response
• Failed emissions inspection results linked to sensor malfunction

Installation Notes

Verify the connector shape, wire count, thread size, and front position before installation. Confirm the vehicle is a 1988-1989 Toyota 4Runner or 1988 Toyota Pickup as listed, and compare the original sensor routing to the 835.0 overall length before fitting. Clean the mounting area and inspect the exhaust bung threads before threading in the new sensor.

Quality Assurance

Delphi applies OE experience and supplier knowledge to this aftermarket oxygen sensor, with product engineering informed by decades of original equipment development. The package includes the oxygen sensor and an instruction sheet.
