Help your automatic climate control respond to changing sunlight with the Standard Ignition Sun Load Sensor EFL182, which senses the intensity of sunlight entering the vehicle so the climate control system can adjust its output. It fits many Toyota and Lexus vehicles, among them the 2009-2010 Toyota Corolla, 2001-2007 Toyota Highlander and 2001-2009 Toyota Prius. See the "Vehicles it fits" section for the full list. It is a direct-fit replacement for the listed applications, which use one sensor each.

Frequently Asked Questions
What does a sun load sensor do?
It measures the intensity of sunlight entering the vehicle and sends that signal to the automatic climate control system, which uses it to help adjust its output.
Is this an oxygen sensor for the 2009-2010 Toyota Corolla?
No. EFL182 is a sun load sensor for the climate control system, not an oxygen sensor. It is listed as a direct-fit sun load sensor for the 2009-2010 Toyota Corolla.
What connector and terminals does this sensor use?
It has one plug-in connector with a polygon shape and two male blade terminals. The sensor attaches with a push-in method.
What is included in the box?
The package contains the sensor only. Mounting brackets are not included, and the listed applications use one sensor each.
What are signs a sun load sensor may need replacing?
Signs include climate control that no longer reacts to changing sunlight, or a stored sun load sensor circuit code. Other faults can cause the same symptoms, so diagnose the cause before replacing the sensor.
