Bosch 13132 Oxygen Sensor - Upstream

Bosch Oxygen Sensor for Upstream Emissions Control

Bosch 13132 is a specific-fit, narrow-band heated oxygen sensor built for upstream air-fuel ratio monitoring. It delivers the signal the ECU uses to maintain stable combustion control and manage emissions in real time.

Compatible with 2000 Dodge Dakota, 2000 Dodge Durango, and 1999-2000 Jeep Grand Cherokee applications listed below, this Bosch Engineered Oxygen Sensor is a direct replacement for vehicles that require a threaded, 4-wire, round-connector sensor.

Key Features

• Bosch Engineered Oxygen Sensor, part number 13132
• Narrow-band heated O2 sensor for upstream placement
• Specific fit with threaded mounting and 18 mm thread diameter
• 4-wire design with female round connector and pin terminals
• Wiring harness included; harness length measures 9.7 in
• Metal housing with high-temperature-resistant construction
• Overall length: 16.5 in; sealing surface to connector end: 11.8 in
• Hex size: 22 mm

Product Details

Bosch 13132 uses a switching-type narrow-band design to measure oxygen content in the exhaust stream and send precise feedback to the engine control unit. Bosch developed this sensor family from its original oxygen sensor technology and later refined it with planar narrowband construction for faster light-off and quicker closed-loop operation. The result is a standard replacement sensor engineered for consistent signal response under heat and vibration.

This part cross-references 56028233AA for the same application. It is a strong match for drivers searching for a 2000 Dodge Dakota upstream oxygen sensor, a 2000 Dodge Durango upstream O2 sensor, or a 1999-2000 Jeep Grand Cherokee upstream oxygen sensor.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel mixture feedback errors
• Slow closed-loop fuel control response
• Emissions test failures tied to upstream sensor readings
• Rough combustion control caused by a worn narrow-band sensor

Installation Notes

Install Bosch 13132 in the upstream position only where specified by the vehicle application. Verify the 18 mm threaded mounting, 4-wire connector style, and harness length before installation. Because this sensor is specific fit, compare the connector shape, terminal count, and wire routing to the original unit before replacement.

For 1999-2000 Jeep Grand Cherokee applications, confirm whether the vehicle is equipped without California Emission System or with 12 in wire and California Emission System, as listed in the fitment data. For 2000 Dodge Dakota and 2000 Dodge Durango applications, use the upstream location shown in the vehicle listing.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development and supplies aftermarket sensors built to OE-proven standards. Bosch 13132 reflects that engineering background with durable materials, optimized heater control, and a design intended to maintain accurate sensor output across demanding operating conditions.
