Detailed Description

Delphi ES20024 is an OE-style oxygen sensor engineered for vehicles that require the specified heated, 4-wire setup and 910 mm lead length. It is listed for rear service on 1995-1996 Dodge Neon and 1995-1996 Plymouth Neon, and for additional Dodge applications including Dakota, Monaco, D100, D150, D250, W100, and W150 where the application notes call for the same overall length. This part number, ES20024, is also cross-referenced to select Bosch and DENSO Auto Parts numbers for the same application.

For buyers searching for a replacement oxygen sensor for a 1995 Dodge Neon rear oxygen sensor, a 1996 Plymouth Neon rear O2 sensor, or a 1992-1993 Dodge Dakota oxygen sensor with 910 mm overall length, this Delphi unit matches the listed fitment details and connector style.

What It Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air-fuel feedback to the engine control system
