Research on Oxygen Sensor for Lexus GS300

Fuel efficiency and engine performance can be optimized by constantly measuring the air/fuel mixture. That is what the oxygen sensor does. It measures the exhaust to provide the engine computer with information on how much gasoline to use. A failed O2 sensor can cause a lot of trouble. The newer your car, the more important it is, as more sensors are added in recent model years and emissions regulations get tighter. Fortunately, an oxygen sensor can be easily replaced to keep all of your car's systems in check.

What Does the Oxygen Sensor in a Car Do?

Primarily in the exhaust manifold, the O2 sensor measures unburned oxygen. This helps to gauge the fuel mixture. Your 2006 Lexus GS300 O2 sensor will determine if the mixture is lean or has a high ratio of oxygen (and too little fuel), or is rich, meaning it has low oxygen content and too much fuel. Both are bad for a car's engine. The best ratio is in the middle, so the exhaust emissions are lowest and the engine can run efficiently. The computer determines this by reading the voltage from the sensor; specific oxygen levels can be determined by the voltage produced.

Symptoms of a Bad O2 Sensor

If GS300 bank 2 sensor 2 has gone bad, you may see the Check Engine light. In addition to failing an emissions test, you might notice that the gas mileage has declined, meaning you have to fill up more often. That's because the engine is burning more fuel rather than knowing it has enough air to work with. The engine timing can be thrown off, as can combustion intervals. Your engine might run more roughly than usual, especially when idling. It could misfire as well. Oxygen sensors normally wear out over time, and should be replaced at a maximum of 90,000 miles, especially if the car is less than 15 years old. Aside from normal wear and tear, O2 sensors can fail due to oil or coolant contamination. If such an issue isn't found, it can damage a new sensor soon after the repair.

Cost of Oxygen Sensor Replacement in a Lexus GS300

Parts are generally more than labor for this repair. For the front 2001 Lexus GS300 oxygen sensor location, changing out one unit is $235 to $332. The rear sensor goes for anywhere from $279 to $387 to replace. Given that you may be saving money on fueling up and preventing serious and costly engine repairs, these rates aren't bad. Labor and other charges based on the car and location can add to the total, but a mechanic who knows the Lexus GS300 oxygen sensor location will do the job right the first time. That will save you time and effort. As far as parts go, you can save even more cash by purchasing an O2 sensor from PartsGeek.com. Better prices are offered thanks to low overhead, which we make sure gets passed on as savings. If you have oxygen sensor problems this means shelling out less cash on an important repair.

Oxygen Sensors available for the following Lexus GS300 years: 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1997, 1996, 1995, 1994, 1993, 06, 05, 04, 03, 02, 01, 00, 99, 98, 97, 96, 95, 94, 93.
