Detailed Description

Delphi ES20213 is an emission control sensor engineered for rear exhaust monitoring on vehicles such as the Toyota Sienna, Toyota Highlander, Lexus RX350, Lexus RX330, Lexus RX400h, Lexus LS460, Scion xB, and Scion tC. It is also listed for Toyota Camry, Toyota Solara, and Toyota Venza rear sensor applications. Delphi’s OE background and supplier experience are reflected in the sensor design, helping support accurate exhaust feedback for the engine management system.

This part cross-references DENSO Auto Parts (e.g., 234-4149, 234-4168) for the same application.

What It Helps Address

  • Check engine light related to rear oxygen sensor performance
  • Fault codes tied to slow sensor response or heater circuit issues
  • Incorrect air-fuel feedback from a worn downstream sensor
  • Emissions test failures caused by aging exhaust monitoring components
  • Rougher fuel control behavior from inaccurate exhaust readings

Installation Notes and Tips

Verify the exact position before ordering, since this sensor is listed for rear, rear left, and rear right locations depending on vehicle application. Confirm thread size, connector shape, and wire count against the original sensor before installation. For fitment, this part is listed for 2002-2015 Toyota and Lexus applications, including Fits 2004-2014 Toyota Sienna, rear left; Fits 2007-2014 Lexus RX350, rear left; and Fits 2008-2015 Scion xB, rear.

Additional listed applications include Fits 2004-2006 Lexus RX330, rear right, except Japan built; Fits 2004-2006 Lexus RX330, rear left, Japan built; and Fits 2002-2003 Toyota Solara, rear.
