Delphi ES10134 Oxygen Sensor

Delphi ES10134 Oxygen Sensor Overview

The Delphi ES10134 is a heated upstream oxygen sensor built for precise exhaust monitoring and reliable engine management feedback. With OE heritage behind the design, it supports accurate air-fuel control for select Ford, Lincoln, and Mercury applications, including 1985-1987 Ford Mustang and 1986 Ford Taurus fitments.

Key Features

• Heated oxygen sensor for faster operating temperature and stable signal output
• 3-wire design with a round connector shape
• 18 x 1.5 mm thread size for direct-thread applications
• 290.0 overall length for listed vehicle fitments
• Upstream position for pre-catalyst exhaust monitoring
• Includes oxygen sensor and instruction sheet
• Delphi ES10134 cross-references DENSO Auto Parts 234-3001 for the same application

Detailed Description

Delphi ES10134 is an upstream heated oxygen sensor engineered for vehicles that rely on pre-catalyst exhaust feedback to manage fuel delivery and emissions performance. Delphi draws on OE experience and supplier knowledge developed over decades of original-equipment service, and that background is reflected in the sensor’s construction and application coverage. This part number is listed for select 1985-1987 Ford, Lincoln, and Mercury models, including Ford E-150 Econoline Club Wagon, Ford Mustang, Lincoln Town Car, and Mercury Cougar applications.

For buyers searching by vehicle and part number, Delphi ES10134 is a direct-reference oxygen sensor for select Ford Mustang oxygen sensor replacement needs, Ford Taurus upstream sensor service, and Lincoln Town Car exhaust sensor repair. It is also referenced under Delphi ES10134 for broader interchange lookup across related OE-style applications.

What It Helps Address

• Check engine light concerns related to oxygen sensor signal faults
• Rough idle or drivability issues caused by inaccurate exhaust feedback
• Fuel mixture problems from a slow or aging upstream sensor
• Emissions test failures tied to sensor response or output degradation
• Poor fuel control on Ford, Lincoln, and Mercury applications using this fitment

Installation Notes and Tips

Confirm the upstream location, connector shape, wire count, and 18 x 1.5 mm thread size before installation. Compare the overall length to the original sensor on the vehicle, especially on applications such as the 1987 Ford E-150 Econoline Club Wagon with 290mm overall length noted in the fitment data. Follow the included instruction sheet and verify the harness routing to avoid strain on the connector.

Quality Assurance

Delphi builds this oxygen sensor using OE heritage and application knowledge developed through long-term original-equipment supply experience. That background supports consistent fitment and signal performance for the listed Ford, Lincoln, and Mercury applications.
