Bosch 17087 Oxygen Sensor - Upstream

Bosch Wideband OE Oxygen Sensor

Bosch 17087 is a specific-fit wideband air-fuel oxygen sensor for upstream applications on select Jaguar and Land Rover models. It delivers high-precision air-fuel ratio feedback to the engine control unit, helping maintain accurate mixture control across changing load and temperature conditions.

Built as an Actual OE Oxygen Sensor, this Bosch unit uses a heated wideband design with a 5-wire harness, blade terminals, and a threaded metal housing for direct replacement service. It is a practical choice for drivers searching for a Bosch 17087 oxygen sensor for Jaguar XE or Land Rover Discovery Sport and Range Rover Evoque upstream locations.

Key Features

• Wideband A/F oxygen sensor for continuous air-fuel ratio measurement
• Heated design for faster sensor operation after startup
• Specific-fit replacement with included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Oblong male connector with 6 terminals and 5 wires
• Metal housing for OE-style durability
• Actual OE Oxygen Sensor line from Bosch

Product Details

Bosch pioneered the wideband oxygen sensor design used in modern engine management, and the 17087 follows that OE development path with a planar pump-cell style sensor architecture. The wideband sensor type provides more detailed feedback than a traditional switching sensor, allowing the ECU to manage fuel delivery with greater precision under steady cruise, acceleration, and load changes. This Bosch 17087 part number is cross-referenced to LR049882 and T2H3281 for the same application.

Compatible With 2017 Jaguar XE, Upstream; 2015-2017 Land Rover Discovery Sport, Upstream; and 2014-2017 Land Rover Range Rover Evoque, Upstream. These fitments make it a direct replacement option for owners looking for an upstream Bosch oxygen sensor for Jaguar XE or Land Rover Discovery Sport and Range Rover Evoque service.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings at the ECU
• Reduced fuel economy from inaccurate mixture control
• Rough running caused by slow or inconsistent sensor response
• Emissions test failures tied to upstream sensor faults

Installation Notes

Verify the connector shape, terminal count, thread size, and upstream location before installation. The sensor uses a threaded mount and includes the wiring harness, so the replacement should match the original routing and connector style on the vehicle. Always confirm fitment against the vehicle’s original part number and sensor location before service.

Quality Assurance

Bosch supplies this sensor as part of its Actual OE Oxygen Sensor line, drawing on more than five decades of OE development and aftermarket sensor production. The design emphasizes fast light-off, controlled heater operation, and robust ceramic construction for consistent performance in demanding thermal conditions.
