Detailed Description

Delphi ES20092 is a front oxygen sensor for 2001-2003 Dodge Ram 1500, 2001-2002 Dodge Ram 2500, 2001-2002 Dodge Ram 3500, 2001-2003 Jeep Wrangler, and 2001-2003 Jeep Grand Cherokee applications listed with front placement. It is also listed for 2002-2003 Jeep Grand Cherokee front for cylinders 1 to 3 only, 2001 Jeep Grand Cherokee front with California Emission System for cylinders 4 to 6 only and cylinders 1 to 3 only, and 2001-2002 Dodge Ram 1500 front without California Emission System, plus 2002 Dodge Ram 2500 and 2002 Dodge Ram 3500 front without California Emission System. Delphi’s OE heritage is built into this aftermarket part for direct-fit replacement needs where the original sensor has failed or drifted out of range. This part cross-references Bosch 13687 for the same application.

What It Helps Fix

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback from the front sensor
• Rough idle or hesitation caused by faulty exhaust readings
• Failed emissions testing tied to sensor response issues
• Reduced fuel control accuracy from a worn heated O2 sensor

Installation Notes and Tips

Verify the front sensor location, connector shape, thread size, and engine/emissions notes before installation. This ES20092 uses a square connector and 18 x 1.5 mm threads, so matching the original connector and mounting point is important for proper fitment on the listed Dodge Ram and Jeep vehicles. Compare the vehicle’s emissions configuration and cylinder-specific notes before ordering.

Quality Assurance

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers. That original equipment background supports consistent design and manufacturing standards in the ES20092 oxygen sensor.
