Bosch 17160 Oxygen Sensor - Upstream Right

Bosch Wideband O2 Sensor for BMW 745i and 745Li

Bosch 17160 is an Actual OE Oxygen Sensor built for precise air-fuel ratio monitoring in wideband applications. It fits the 2002 BMW 745i and 2002 BMW 745Li in the upstream right position, where accurate sensor feedback is critical for engine management and emissions control.

Key Features

• Wideband A/F oxygen sensor for continuous lambda measurement
• Heated design for faster light-off and stable operation
• Specific-fit sensor with 5-wire harness and 6 terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing with robust ceramic construction for thermal durability
• Wiring harness included with 21.1 in harness length and 24.4 in overall length
• OE-style replacement from Bosch Actual OE Oxygen Sensor line

Detailed Description

Bosch 17160 uses wideband sensing technology to provide the ECU with detailed air-fuel ratio data across the full lambda range. That level of signal resolution supports precise mixture control during idle, acceleration, and load changes, which is especially important on the BMW 745i and BMW 745Li upstream right sensor location. Bosch’s Actual OE Oxygen Sensor line reflects the company’s OE development background and its role in the original planar pump-cell wideband design used in modern engine management systems.

This Bosch oxygen sensor is a standard replacement part with a male oblong connector, blade terminals, and threaded mounting. The heated sensor design helps it reach operating temperature quickly, while the included harness and specific-fit configuration simplify matching the factory connection layout. Part number 17160 is also a direct reference point for shoppers comparing Bosch 17160 against OE-style replacement options for the same application.

This part cross-references Bosch 17160 for the same application.

What It Helps Address

• Incorrect air-fuel ratio readings from a worn upstream sensor
• Check engine light conditions related to oxygen sensor performance
• Rough idle or hesitation caused by inaccurate mixture feedback
• Reduced fuel economy from poor fuel-trim control
• Elevated emissions from delayed or inconsistent sensor response

Installation Notes and Tips

Install this sensor in the upstream right position only on confirmed applications. Verify connector shape, wire count, thread size, and harness length before installation. Because this is a threaded wideband sensor, use the correct oxygen sensor socket and avoid contaminating the sensing element during handling. Confirm the vehicle is a 2002 BMW 745i or 2002 BMW 745Li before ordering Bosch 17160.

Quality Assurance

Bosch backs this Actual OE Oxygen Sensor with OE-proven engineering and durable construction developed for modern emission control systems. The sensor is built to deliver reliable signal accuracy under thermal cycling and rapid load changes, matching the expectations of factory-style engine management on the BMW 745i and BMW 745Li.
