Bosch 15124 Oxygen Sensor - Downstream, Upstream or Upstream Right

Bosch Actual OE Oxygen Sensor 15124

Bosch 15124 is a specific-fit, narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management for select Chrysler, Dodge, Jeep, and Volkswagen applications, including Chrysler Sebring, Dodge Avenger, and Jeep Patriot fitments.

Key Features

• Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
• Narrow-band heated O2 sensor for closed-loop fuel control
• Specific fit with threaded mounting and 18 mm thread size
• 4-wire design with pin terminals and rectangular female connector
• Wiring harness included; harness length measures 10.2 in
• Metal housing with high-temperature-resistant construction
• Overall length: 13.5 in; sealing surface to connector end: 12.3 in
• Hex size: 22 mm

Product Details

Bosch 15124 uses a switching-type narrow-band design that measures oxygen content in the exhaust stream and sends accurate feedback to the engine control unit. Bosch developed this sensor family from its early OE oxygen sensor work and later planar narrowband designs, focusing on faster light-off, improved lambda accuracy, and quicker closed-loop operation. For drivers searching for a Bosch 15124 oxygen sensor for Chrysler Sebring, Dodge Caliber, or Jeep Compass, this OE-style replacement is built to match the original sensor layout and electrical connection requirements.

This part cross-references Mopar 56029084AA for the same application.

What It Helps Address

• Check engine light caused by oxygen sensor signal faults
• Rich or lean fuel trim conditions from inaccurate exhaust feedback
• Slow closed-loop response during warm-up or normal driving
• Emissions test failures related to sensor performance
• Rough combustion control from a worn upstream or downstream sensor

Installation Notes and Tips

Verify the sensor position before ordering, since Bosch 15124 is used in upstream, downstream, and upstream right locations depending on the vehicle. Confirm the connector shape, 4-wire layout, and 18 mm thread size against the original part. Use the correct oxygen sensor socket or 22 mm hex tool, and inspect the harness routing so the lead is not twisted, stretched, or routed near hot exhaust components.
