If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less exact when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2012 Lexus GX 460's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the right mixture of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a car to fail an emissions test.
• One of the most regular and countless cause is that your 2012 Lexus GX 460 gas cap is loose, damaged or missing. The gas cap for your 2012 Lexus GX 460 serves multiple purposes.

If your gas cap is classical or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive.

If your spark plugs or spark plug wires are harmful or classical, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, big to more expensive repairs.

When your 2012 Lexus GX 460's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t definite, a computer turns on your check engine light. This amber or yellow light is normally labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

This code is read with an electronic audit tool that is used by our Lexus auto repair mechanics at Nalley Lexus Smyrna. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you select that route too.
