Bosch 13272 Oxygen Sensor - Downstream or Upstream

Bosch Oxygen Sensor 13272 Overview

Bosch 13272 is a narrow-band heated oxygen sensor built for direct-fit emission control service on select Chrysler, Dodge, and Plymouth vehicles. It provides the ECU with air-fuel-ratio feedback for stable closed-loop operation, cleaner combustion, and consistent drivability.

As part of the Bosch Engineered Oxygen Sensor line, this sensor reflects Bosch’s OE-focused development in switching-type O2 sensing, with ceramic sensing elements, controlled heater performance, and materials selected for high-temperature and vibration exposure.

Key Features

• Part number 13272 Bosch oxygen sensor for specific vehicle applications
• Narrow-band heated oxygen sensor with 4-wire configuration
• Threaded mounting with 18 mm thread size and 22 mm hex size
• Round female connector with included wiring harness
• Specific-fit replacement for upstream and downstream locations
• Metal housing with standard replacement grade construction
• Designed for stable lambda feedback under changing engine conditions

Detailed Description

Bosch 13272 is engineered for vehicles that rely on a switching-type O2 sensor to monitor exhaust oxygen content and relay that information to the engine control unit. The sensor’s heated narrow-band design helps it reach operating temperature quickly, supporting faster closed-loop control after startup and more consistent signal response during normal driving. This makes it a practical replacement for service on Chrysler 300M, Concorde, Intrepid, LHS, Cirrus, Sebring, Neon, Prowler, PT Cruiser, Dodge Intrepid, Dodge Stratus, and Plymouth Breeze applications listed below.

Built with Bosch’s long OE development history, the Bosch Engineered Oxygen Sensor line focuses on accurate feedback, durable construction, and dependable operation in demanding exhaust environments. Part number 13272 is a direct-fit style sensor for specific applications, with a 13.4 in overall length, 9.7 in wiring harness length, and 12.2 in sealing-surface-to-connector length.

This part cross-references Chrysler 4606133AC and 4606133AE for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle or unstable air-fuel control from a worn sensor
• Delayed closed-loop operation after cold start
• Reduced fuel control accuracy from aging narrow-band feedback
• Emission test failures tied to faulty exhaust oxygen sensing
