How many O2 sensors does a 2000 Lexus gs300 have?
Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
What are the sensors on a Lexus GS300?
One of these sensors is an oxygen sensor, which on a Lexus GS300 is placed along the exhaust. If one of the oxygen sensors is reading incorrectly, then the computer won’t know how much fuel or spark to give the engine, and the result will be choppy idle and loss of power.
How to check and replace an oxygen sensor ( air )?
A P1155 or P1135 code indicates you have a bad sensor. This is common in Toyota and Lexus cars and trucks. Learn how to test the air fuel ratio sensor to see if it is bad, and then learn how to replace the bad sensor. Nice O2 Sensor Socket Kit: http://www.amazon.com/gp/product/B005…
How do you remove an oxygen sensor from a ratchet?
Place the oxygen sensor socket onto the end of a 3/8-inch ratchet and place it over the oxygen sensor. There is a slot on the oxygen sensor socket that will allow the wire lead from the oxygen sensor to run out the side and not get damaged. Remove the oxygen sensor and discard it.
What’s the difference between AFR and O2 sensors?
What distinguishes Air Fuel Ratio Sensors from regular O2 sensors is that the AFR Sensor is what is known as a wide range O2 sensor whereas the basic O2 sensor is a narrow range sensor. It can detect a wider range of air/fuel ratios than the basic O2 sensor.
One of these sensors is an oxygen sensor, which on a Lexus GS300 is placed along the exhaust. If one of the oxygen sensors is reading incorrectly, then the computer won’t know how much fuel or spark to give the engine, and the result will be choppy idle and loss of power.
How do you replace an exhaust oxygen sensor?
Remove the oxygen sensor and discard it. Place the replacement oxygen sensor in the bung on the exhaust and tighten it in place using the oxygen sensor socket and the ratchet. Reconnect the wiring harness to the pigtail on the sensor. Repeat the process for any additional sensors on the exhaust.
Where do you place an oxygen sensor on a ratchet?
Place the oxygen sensor socket onto the end of a 3/8-inch ratchet and place it over the oxygen sensor. There is a slot on the oxygen sensor socket that will allow the wire lead from the oxygen sensor to run out the side and not get damaged.
