Bosch 13130 Oxygen Sensor - Upstream

Bosch Validated Oxygen Sensor for Jeep Grand Cherokee

Bosch Validated Oxygen Sensor 13130 is a standard replacement narrow-band heated O2 sensor built for precise air-fuel-ratio feedback to the ECU. It is a direct-fit, threaded sensor with a round female connector and included wiring harness for select 1999-2000 Jeep Grand Cherokee upstream applications with California Emission System calibration.

Key Features

• Direct-fit Bosch Validated Oxygen Sensor, part number 13130
• Narrow-band heated design for closed-loop fuel control
• Specific fit with threaded mounting and 18 mm thread size
• 4-wire configuration with round female connector
• Wiring harness included; harness length measures 15.6 in
• Metal housing with high-temperature-resistant construction
• 22 mm hex size for service access

Product Details

Bosch Validated Oxygen Sensor 13130 uses a narrow-band sensing element to report exhaust oxygen content to the engine control unit, helping maintain stable combustion control and emissions performance. Bosch’s oxygen sensor development includes early thimble-style designs and later planar narrowband technology, with a focus on faster light-off, accurate lambda feedback, and quicker closed-loop operation. This sensor is a specific-fit replacement for select Jeep Grand Cherokee upstream locations and is listed for California Emission System vehicles.

Compatible With: 1999-2000 Jeep Grand Cherokee, Upstream. This part cross-references Mopar 56028232AA for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Delayed or unstable closed-loop fuel control
• Rich or lean exhaust feedback readings
• Emissions test failures tied to upstream sensor output
• Rough combustion control caused by aging sensor response

Installation Notes and Tips

Install this sensor in the upstream exhaust location specified for the vehicle application. Verify the connector style, wire length, and 18 mm threaded mounting before installation. Because this is a heated narrow-band sensor, proper electrical connection and secure routing of the included harness are important for reliable operation. Use the 22 mm hex for removal and installation, and confirm the California Emission System application matches the vehicle before ordering.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development and supplies aftermarket sensors built to OE-proven standards. Bosch Validated Oxygen Sensor 13130 is engineered for durable operation under heat and vibration, with materials selected for consistent signal performance in demanding exhaust environments.
