Can a damaged oxygen sensor fail an emissions test?
Bear in mind: A non-functional or visibly damaged oxygen sensor may cause you to fail an emissions test if you live in an area that requires regular emissions testing. Your Emissions System Maintenance Shopping List Here is a list of emissions parts to look at if you have problems passing your local emissions tests: Oxygen Sensor
What happens when you change the O2 sensor?
The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it.
Why are oxygen and catalyst sensors not ready?
Oxygen and catalyst sensors… Just had the charcoal canister replaced, check engine light is now off, but oxygen and catalyst sensors are showing as ‘not ready’ and vehicle will not pass emissions. Car has been driven over 200 miles and sensors still show ‘not ready’ Battery was replaced last summer.
Is it possible to bypass the oxygen sensor?
Bypassing your oxygen sensor is an efficient way to tune your engine. If you’re into off-road racings or are less skilled in tuning engines, then this may be your most effective option. Not only that, as an added bonus, it helps engines revoke casual system errors.

Why is the oxygen sensor not ready for the drive cycle?
These constantly monitor the sensors, the fuel mixture, and the occurrence of misfires. If the oxygen sensor heater monitor is not ready, check to see how many other monitors are not ready. If the oxygen sensor and catalyst monitors are also not ready, the culprit is most likely a weak battery.

What happens if you fail an emissions test?
Nobody wants to fail an emissions or smog test: it means you have to figure out what caused the failure and get it fixed. Then you have to return for a re-test.
What causes a high HC reading on an emissions test?
Let’s start by understanding what things cause a high HC reading. A high HC reading means the test found high HC (hydrocarbons) in your emissions. In other words, too much gas is left in the exhaust after combustion.
What to do if your car fails the NOx test?
If you own a non-EGR equipped vehicle, and have failed the emissions test for high NOx, pay close attention to the Catalytic Converter. Read about Catalytic Converter
What causes a car to fail the emissions test?
More common trouble codes that cause vehicles fail on emissions test and make the Check Engine light coming on can found below. Even fouled or the worn out catalytic converter is the most cause failed on test, based on above data you will get a somewhat different picture, if all of the related codes by system or component to be combined.

What do they look for in an emissions test?
These tests measure the amount of tailpipe emissions produced by car engines, in order to check whether a vehicle meets the regulations that restrict emissions of specific pollutants. They measure levels of nitrogen oxide (NOx), carbon monoxide (CO), particulate matter (PM), non-methane organic gases (NMOG), and formaldehyde (HCHO).
