Bosch 15465 Oxygen Sensor - Downstream

Bosch Oxygen Sensor for Jeep Downstream Applications

Bosch Part Number 15465 is a narrow-band heated oxygen sensor built for specific downstream applications on select Jeep models. It provides air-fuel-ratio feedback to the ECU for stable closed-loop control, accurate lambda monitoring, and lower emissions performance.

Compatible with 2000-2001 Jeep Cherokee, downstream; 2000 Jeep TJ, downstream; and 2000 Jeep Wrangler, downstream, this Bosch Engineered Oxygen Sensor is a direct-fit standard replacement for the listed vehicles.

Key Features

• Specific-fit oxygen sensor for listed Jeep applications
• Narrow-band heated design for faster closed-loop operation
• 4-wire configuration with pin terminals and round connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Steel-finish metal housing for high-temperature service
• Wiring harness included with 6.9 in harness length
• Overall length: 13.4 in; sealing surface to connector end: 9.4 in

Product Details

Bosch Engineered Oxygen Sensor Part Number 15465 uses Bosch narrow-band sensor technology developed from decades of OE oxygen sensor engineering. The heated switching-type design measures exhaust oxygen content and sends precise feedback to the engine control unit, helping maintain proper combustion control across changing operating conditions. For Jeep Cherokee, Jeep TJ, and Jeep Wrangler downstream service, this sensor supports accurate emissions monitoring and consistent drivability.

This part cross-references 56044215AA for the same application.

What This Sensor Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect air-fuel ratio feedback to the ECU
• Rough idle or unstable closed-loop fuel control
• Failed emissions inspection tied to oxygen sensor performance
• Slow sensor response from a worn heated narrow-band unit

Installation Notes

Install in the downstream exhaust position only for the listed Jeep applications. Verify the 18 mm thread size, 4-wire connector style, and round female connector before installation. Use proper oxygen sensor service tools and follow factory torque specifications to avoid thread damage or exhaust leaks.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development, and this Bosch Engineered Oxygen Sensor line reflects that experience with OE-proven sensor design, ceramic sensing elements, and heat-resistant materials for demanding exhaust conditions.
