Bosch 17036 Oxygen Sensor - Upstream or Upstream Left

Bosch Wideband O2 Sensor for Volvo S80

Bosch 17036 is an Actual OE Oxygen Sensor built for precise air-fuel ratio monitoring in wideband applications. It delivers fast, detailed feedback to the ECU for accurate mixture control, stable engine operation, and lower emissions on the vehicles listed below.

The Bosch Actual OE Oxygen Sensor line focuses on OE-style fit, sensor accuracy, and durable construction. This wideband A/F sensor uses a heated design, a threaded mounting style, and a specific-fit harness layout to match the original application on select Volvo S80 models.

Key Features

• Wideband air-fuel ratio sensor for continuous lambda measurement
• Heated sensor design for faster operating temperature
• Specific-fit replacement with included wiring harness
• 5-wire configuration with 6 terminals and rectangular male connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Overall length: 31.5 in; harness length: 28.1 in
• Metal housing with steel finish for OE-style durability

Detailed Description

Bosch 17036 is a wide band oxygen sensor engineered for direct replacement in select Volvo S80 applications. It measures the air-fuel ratio across the full lambda range, giving the engine control unit more precise data than a traditional switching sensor. That level of feedback supports accurate fuel delivery and cleaner combustion under changing load and temperature conditions. This part cross-references Bosch 17036 for the same application.

Compatible With 1999-2001 Volvo S80, upstream and 2002-2004 Volvo S80, upstream left. If you are searching for a Volvo S80 upstream oxygen sensor, Bosch 17036 is the OE-style replacement to verify against your original sensor connector, harness length, and mounting details.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings
• Rough idle caused by inaccurate mixture control
• Reduced fuel economy from poor sensor feedback
• Emissions test failures tied to sensor response issues

Installation Notes and Tips

Confirm the connector shape, wire count, thread size, and sensor position before installation. This Bosch oxygen sensor uses a threaded mount and a specific-fit harness, so matching the original upstream location on the Volvo S80 is important. Inspect the exhaust bung threads and wiring routing before tightening the sensor to specification.

Quality Assurance

Bosch developed the first wideband A/F oxygen sensor and continues to supply OE-proven sensor technology to the aftermarket. Bosch 17036 is built with the same focus on measurement accuracy, heater control, and thermal durability used in modern engine management systems.
