Bosch Oxygen Sensor for Jeep Liberty

Bosch Part Number 13672 is a specific-fit, narrow-band heated oxygen sensor for the downstream right position on 2002-2003 Jeep Liberty models. It monitors exhaust oxygen content and sends air-fuel-ratio data to the ECU for closed-loop fuel control and emissions management.

Key Features

  • Specific fit for 2002-2003 Jeep Liberty, downstream right
  • Narrow-band heated oxygen sensor design
  • 4-wire configuration with rectangular female connector
  • Threaded mounting with 18 mm thread diameter and 22 mm hex size
  • Wiring harness included for direct replacement use
  • Bosch Engineered Oxygen Sensor line built on OE development experience

Product Details

Bosch 13672 is part of the Bosch Engineered Oxygen Sensor line, which draws on Bosch’s long history of OE oxygen sensor development. This sensor uses a heated narrow-band design to provide stable signal response after startup and consistent feedback during normal driving conditions. For Jeep Liberty owners searching for a downstream right oxygen sensor replacement, Bosch 13672 offers the correct fitment and connector style for the listed application.

This part cross-references Mopar 56041953AA for the same application.

Common Problems This Sensor Can Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel ratio feedback to the ECU
  • Slow closed-loop fuel control response
  • Emissions test failure caused by a faulty downstream sensor
  • Rough combustion control from an aging exhaust sensor

Installation Notes and Tips

Verify the downstream right location before installation on your Jeep Liberty. The sensor uses a threaded mount with a 18 mm thread size, so the exhaust bung threads should be clean and undamaged before tightening. Confirm the connector shape, terminal count, and harness routing match the original sensor before final assembly.

Quality Assurance

Bosch manufactures oxygen sensors with OE-level engineering and durable materials selected for high-temperature and vibration exposure. The Bosch Engineered Oxygen Sensor line is developed to deliver accurate signal control and dependable service in demanding exhaust environments.
