Product Details

Denso 234-4228 is part of the OE Style line, which focuses on direct-replacement fit and factory-style performance. For 2002-2003 Jeep Liberty applications, this upstream right oxygen sensor is built to match the original installation point and electrical configuration, helping maintain proper air-fuel feedback for the engine management system. Denso uses precision manufacturing and testing to OE standards, and the sensor design includes an aluminum oxide trap layer that helps protect the ceramic element from silicone and lead contamination.

This part cross-references Bosch 13670 and NTK 23138 for the same application.

Common Issues This Sensor May Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel ratio feedback from the upstream right sensor
  • Reduced fuel economy caused by a worn or slow-responding sensor
  • Rough idle or drivability concerns tied to exhaust sensor input
  • Emission test failures linked to faulty oxygen sensor readings

Installation Notes and Tips

Compatible With 2002-2003 Jeep Liberty, upstream right. Verify connector style, wire count, thread diameter, and harness length before installation. Because this is a specific-fit threaded sensor, confirm the mounting location and routing match the original sensor on the vehicle. Use the vehicle’s service information for proper removal and torque procedures.

Quality Assurance
