What should I do if my oxygen sensor goes bad?
More often than not, when an oxygen sensor in your Silverado goes bad, it will throw a diagnostic trouble code. There are many oxygen sensor related codes. These codes correspond with what side of the engine they are on (known as the “bank” for cylinder bank) and how far down stream they are.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
Why is the O2 sensor called the oxygen sensor?
Also known as the (O2) sensor because (O2) is the chemical formula for oxygen. The (O2) oxygen sensor monitors how much unburned oxygen is present in the exhaust as the exhaust exits the engine. So, by monitoring oxygen levels; the sensor provides a means of measuring fuel mixture.
What are the symptoms of an O2 sensor failure?
(O2) Oxygen Sensor, Failure Symptoms: 1 Poor gas mileage. 2 Loss of power. 3 Black smoke from tailpipe. 4 Emissions test failure. 5 Rough idle. 6 Hesitation or stalling. 7 Check engine light comes on.
When does an O2 sensor set a trouble code?
If it’s not switching rapidly, the ECM will set an O2 sensor related trouble code If the upstream and downstream oxygens sensors are both switching from rich to lean, that’s the sign of a dead catalytic converter. An exhaust system leak really screws up the P0420 testing routing.
Do you need to replace your oxygen sensor?
Replacement of good oxygen sensors is one of the common mistakes that both seasoned auto repair mechanics and do it yourself driveway mechanics will make when tackling rich or lean diagnostic codes. I am not saying that these O2 sensor codes never require the replacement of the sensor itself.
