What precautions and steps are involved in servicing oxygen sensors, including replacement procedures for both upstream and downstream sensors in Toyota Highlander?

Handle oxygen sensors with care as damage to the attached pigtail and electrical connector can render them useless. Avoid contaminants and cleaning solvents. For replacements, 2008 and later models have the air-fuel ratio sensor which is the upstream sensor, and the oxygen sensor, which is the downstream sensor. For four-cylinder models, disconnect the battery cable, locate the sensor in the exhaust manifold, disconnect the connector, and unscrew the sensor using an oxygen sensor socket. For V6 models, disconnect the battery cable, disconnect the sensor connector, raise the vehicle, and unscrew the sensor. Always apply anti-seize compound to the sensor threads during installation and tighten to the specified torque.

Toyota Highlander Oxygen Sensor

In Toyota Highlander, one of the most important components mainly used for monitoring and regulating the air fuel mixture contained in the engine exhaust is the Oxygen Sensor. Analyzing the amount of unused oxygen and the standard atmospheric level the sensor produces a voltage level that helps the engine control computer to modify the mixture through the fuel injector's pulse width. Generally, Toyota Highlander possess not less than two oxygen sensors; the pre-cat and post-cat ones while the pre-cat is considered as the most essential one due to its ability to provide feedback. These sensors work efficiently at high temperatures but, over time, they can be contaminated and cause higher emission and poor fuel economy. Some of the modern cars may incorporate the air-fuel ration sensors if the their values are to be measured and controlled for improved fuel delivery.
