Bosch 13320 Oxygen Sensor - Upstream

Bosch Oxygen Sensor for 2000 Neon

Bosch Part Number 13320 is a specific-fit, narrow-band heated oxygen sensor for select 2000 Dodge Neon and 2000 Plymouth Neon upstream applications. It provides the ECU with air-fuel-ratio feedback for stable closed-loop fuel control and lower emissions.

Key Features

• Specific-fit Bosch Engineered Oxygen Sensor for direct application matching
• Narrow-band heated O2 sensor for faster closed-loop operation
• 4-wire design with round female connector and pin terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included for a cleaner replacement setup
• Steel-finish metal housing built for high-temperature and vibration exposure

Product Line Details

Bosch Engineered Oxygen Sensor products draw on Bosch OE development dating back to the original oxygen sensor designs introduced in 1976. This line uses ceramic sensing elements, controlled heater operation, and durable materials to deliver accurate lambda feedback and consistent performance across changing engine loads.

Detailed Description

This Bosch 13320 oxygen sensor is built for upstream placement on 2000 Dodge Neon and 2000 Plymouth Neon models, except Ultra Low Emission Vehicle (ULEV) versions. As a narrow-band heated sensor, it monitors exhaust oxygen content and sends the signal the engine control unit uses to adjust fuel delivery. Bosch’s OE-focused sensor design emphasizes fast light-off, stable measurement, and reliable operation under thermal stress.

Use Bosch Part Number 13320 when replacing a worn upstream O2 sensor on a 2000 Dodge Neon or 2000 Plymouth Neon. The threaded, specific-fit design helps maintain proper exhaust sealing and sensor response for emissions control and drivability.

This part cross-references 5269866 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle caused by inaccurate air-fuel feedback
• Increased fuel consumption from poor closed-loop control
• Failed emissions testing tied to upstream sensor faults
• Slow sensor response after heat cycling or age-related wear

Installation Notes and Tips

Confirm upstream location and verify that the vehicle is not an Ultra Low Emission Vehicle (ULEV) before ordering. Match the 18 mm thread size, 22 mm hex, 4-wire connector layout, and round female connector to the original sensor. Inspect the harness routing and connector condition before installation to avoid signal issues after replacement.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development and aftermarket sensor engineering. The design reflects Bosch’s focus on accurate measurement, durable construction, and consistent performance in demanding exhaust environments.
