Unquestionably the o2 sensor is certainly the most crucial sensor in your vehicle. Whenever this specific sensor does not work properly, or perhaps even becomes degraded, then simply performance, economy, as well as emissions can suffer significantly. Not many people realize that the o2 sensor, in contrast to almost every other sensor in the vehicle, is actually a consumable item. This would mean that the o2 sensor has some limited lifetime relating to service and is also intended to end up renewed in the event it wearing out. However, this is typically the one sensing unit on the motor vehicle which usually is a wear item.
The O2 sensor (from a Chevy)
Folks question how frequently the actual oxygen sensor has to be replaced. I’ve seen oxygen sensors continue to function as originally intended after 100,000 miles, plus I’ve come across completely new o2 sensors go wrong more or less right away as a result of other difficulties because of the car engine. However, on your normal, common-service engine, I personally explain to people to replace the oxygen sensors whenever they begin to change his or her’s auto tires, this also usually means that oxygen sensors usually should be changed between 35,000 to 50,000 miles.
In the event the automobile isn’t driven on a regular basis, I suggest changing sensors between 17,500 to 25,000 miles. Typically the replacement price of a new sensor pales in comparison to the amount of fuel usage wasted due to a deteriorated or simply poor sensor. Often times though, it might take quite some time just before a poor sensor degrades enough to truly have the ECM set any DTC (Diagnostic Trouble Codes) plus light up the MIL, aka the ‘check engine light’. Not to mention the wasted fuel due to the engine not functioning 100% due to a simple o2 sensor.
In my next article I’m going to explain what causes an o2 sensor to fail, & how to have it replaced.
Also if you’re stuck on any o2 sensor trouble codes. I might be able to assist. Just post the code below.
Anyway, I’ve included a video (at the top of this post) for your viewing pleasure on the exciting o2 sensor!
