Detailed Description

Delphi ES20032 is an emission control oxygen sensor engineered for precise fitment on select 1988-1992 Toyota and Lexus models. It is listed for applications including 1988 Toyota Camry front, 1988 Toyota MR2, 1988-1989 Toyota Celica, 1989-1991 Toyota Camry, 1989-1991 Toyota Pickup, 1990-1991 Lexus ES250, and 1990-1992 Toyota Land Cruiser left.

Delphi’s OE heritage and supplier experience are reflected in the sensor’s design and application coverage. This part cross-references Bosch 15711 and DENSO Auto Parts 234-4051 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings
• Rough idle caused by aging exhaust feedback sensors
• Reduced fuel economy from a slow or inaccurate sensor signal
• Emissions test failure tied to sensor response issues

Installation Notes and Tips

Verify the exact position on your vehicle before ordering, since this part is listed for front, left, and rear locations depending on application. Confirm the 4-wire connector, square plug shape, 18 x 1.5 mm thread, and 375.0 overall length match the original sensor. On Toyota Pickup models, check whether your vehicle uses California emissions equipment or standard emissions equipment before installation. Use the included instruction sheet and follow proper exhaust-thread service procedures during replacement.

Quality Assurance

Delphi builds aftermarket parts using OE experience and application knowledge developed through long-term original equipment supply. The ES20032 is engineered to meet the fit and function requirements of the listed Toyota and Lexus applications.
