OE-Style Replacement Details
Delphi ES10260 is engineered with OE heritage and supplier experience built into the part, giving it the fit and function expected in emission control service. This upstream oxygen sensor is used in the exhaust stream to monitor air-fuel mixture data for the engine control system. It is a direct replacement choice for Mercedes-Benz 420SEL, Mercedes-Benz 560SEC, and Mercedes-Benz 560SEL models within the listed years, and it cross-references DENSO Auto Parts 234-3081 for the same application.
Common Issues This Sensor Can Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel mixture readings from a worn upstream sensor
- Reduced fuel control accuracy during closed-loop operation
- Emissions test failures tied to sensor response issues
- Hard starting, rough idle, or drivability concerns linked to faulty exhaust feedback
Installation Notes and Tips
Verify the connector shape, 3-wire configuration, thread size, and upstream location before installation. Compare the original sensor length and harness routing to the Delphi ES10260, and confirm the vehicle application against the listed Mercedes-Benz fitment: 1986-1991 Mercedes-Benz 420SEL, 1986-1991 Mercedes-Benz 560SEC, and 1986-1991 Mercedes-Benz 560SEL. Use proper oxygen sensor service tools and follow the included instruction sheet for installation steps.
Quality Assurance
Delphi builds this oxygen sensor using OE experience and application knowledge developed through supplying major automakers. The ES10260 is a practical emission control replacement for drivers servicing Mercedes-Benz 420SEL, 560SEC, or 560SEL models and looking for a sensor that matches factory-style specifications.
