Why Your Oxygen Sensor Shouldn’t Be Ignored

9 Oct

If you’ve noticed your car performing inconsisently, can’t pass inspection due to poor emissions performance, with poor fuel economy, or running like a raped ape somedays, and like a 3 legged dog on others, it could be a faulty oxygen sensor. The 02 sensor is partially responsible for telling the ecu what to do and when. When they are new, 02 sensors relay accurate info very quickly to the ecu. When they age, or get contaminated, they act lazy, slowly relaying info, and performance and economy suffer as a result. We offer a full range of direct replacement 02 sensors from Bosch and Denso, 2 of the largest OEM suppliers in the automotive world. In fact Bosch invented the 02 sensor! These are plug and play, not some cheesy universal joint you’ve got to spend timing soldering in. Waterproof connections ensure years of reliable service. No sense paying the dealer more for the same part in a different box!

So why is it important to replace? As the sensors age, they get contaminated. Remember, these sensors sit right in the catalytic converter and the exhaust pipes, so they are forced to live in a dirty, nasty environment. As time goes on, contaminents build on the sensor itself, and it’s no longer able to react with the speed that modern ecu’s demand. These contaminants also can cause false readings to the ecu, causing the car to run significantly richer, or leaner, than it should. This can have systemic results in other areas of the car. Not only will you get poor performance and poor fuel economy, overly rich conditions can clog cats and cause injectors to stick open. Overly lean conditions can wreak havoc on your internals causing knock, as well as potential piston damage.

If you run race gas, methanol or alcohol injection, this can also cause premature 02 sensor failure. Thankfully, these sensors are affordable, and very easy to replace yourself
