Bosch 15299 Oxygen Sensor - Upstream

Bosch Validated Oxygen Sensor for Chrysler and Dodge

Bosch Validated Oxygen Sensor 15299 is a narrow-band heated upstream O2 sensor built for specific-fit replacement on select Chrysler Sebring and Dodge Stratus applications. It provides the ECU with accurate air-fuel-ratio feedback to support stable combustion control and lower emissions.

For 2003-2004 Chrysler Sebring and 2003-2004 Dodge Stratus, this Bosch oxygen sensor matches the listed upstream applications and includes the wiring harness for a direct replacement-style repair. Bosch part number 15299 is part of the Bosch Validated Oxygen Sensor line, which focuses on OE-proven fit and performance for emission control service.

Key Features

• Specific-fit narrow-band heated oxygen sensor
• Upstream application for select Chrysler Sebring and Dodge Stratus models
• 4-wire design with square female connector and pin terminals
• Threaded mounting with 18 mm thread size and 22 mm hex size
• Wiring harness included for the listed application
• Metal housing with standard replacement grade construction
• Bosch part number 15299 for easy identification

Detailed Description

Bosch 15299 uses a narrow-band sensing element to monitor exhaust oxygen content and send precise feedback to the engine control unit. That signal helps the ECU maintain the correct air-fuel mixture during closed-loop operation, which is important for drivability, fuel control, and emissions compliance. Bosch’s oxygen sensor development includes long-term OE engineering experience, and this Validated Oxygen Sensor line carries that approach into aftermarket replacement service.

This sensor is listed for 2003 Chrysler Sebring, 2004 Chrysler Sebring, 2003 Dodge Stratus, and 2004 Dodge Stratus in the upstream position. It is a direct-fit option for vehicles with the specified configuration, including the 2004 Chrysler Sebring and 2004 Dodge Stratus notes calling for the current generation engine controller (NZC), black connector, and 17 in wire. If you are searching for a Bosch 15299 oxygen sensor for Chrysler Sebring or Dodge Stratus upstream replacement, this part matches the documented application data.

This part cross-references Mopar 4606555AD for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Rough idle or unstable closed-loop fuel control
• Failed emissions inspection caused by sensor degradation
• Slow sensor response from an aging upstream O2 sensor

Installation Notes and Tips

Confirm the vehicle year, make, model, and upstream position before ordering Bosch 15299. Verify connector style, wire length, and engine controller notes against the existing sensor on the vehicle, especially on 2004 Chrysler Sebring and 2004 Dodge Stratus applications. The sensor uses a threaded mount with an 18 mm thread size, so proper removal and installation tools are recommended to avoid damage to the exhaust bung.

Because oxygen sensors operate in high-heat exhaust locations, inspect the harness routing and connector condition during replacement. Make sure the replacement sensor is seated fully and the wiring is kept clear of hot exhaust components.

Quality Assurance

Bosch Validated Oxygen Sensor 15299 is backed by Bosch’s OE development history in oxygen sensing technology, including narrow-band designs used for precise lambda control and reliable closed-loop operation. The part is built as a standard replacement sensor for the listed Chrysler Sebring and Dodge Stratus applications.
