What does the O2 sensor on a catalytic converter do?
This O2 sensor monitors the operating efficiency of the catalytic converter. If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor, it is a sign that the catalytic converter is not working properly.
When do I need to replace the oxygen sensor?
If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor, it is a sign that the catalytic converter is not working properly. Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter.
Where are the oxygen sensors in a car?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
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.
How do you replace the O2 sensor in a car?
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. Open the fuse panel in the driver-side foot well, under the steering column, by pulling down on it with your fingers.
This O2 sensor monitors the operating efficiency of the catalytic converter. If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor, it is a sign that the catalytic converter is not working properly.
How much does it cost to replace an oxygen sensor?
A new oxygen sensor can cost from less than $100 on some models to $300 or more on others, but that doesn’t include labor, which can vary widely by vehicle because of where the sensors are located. As a result, the full cost of oxygen sensor replacement may vary greatly depending on the type of vehicle you drive.
When did they start putting oxygen sensors in cars?
Due to the ODB-II regulations that apply to cars manufactured in 1996 and after, many newer cars have multiple O2 sensors. In fact, some cars have as many as four oxygen sensors.
Why does the Check Engine light go off on my Hyundai Tucson?
The engine looses power for a while, check engine light comes on, then problem corrects itself and check engine light goes off. Shops never see anything because the engine sensor reset and don’t store in memory why the check engine light comes on.
Are there any problems with the Hyundai Tucson?
It has the locking 4WD which was the last year they offered it with the standard transmission. So far at 48,000 no problems whatsoever except for a leak in the power steering unit which they replaced without a problem. I find the 2 liter plenty powerful with the standard tranny although very steep hills are a problem. I routinely use it to haul.
What happens when an O2 sensor goes bad in a Hyundai Tucson?
Oxygen sensors play a vital role in both engine management and emissions control. When an O2 (oxygen) sensor go bad, it’ll cause your Hyundai Tucson ‘s engine to run less efficiently. Your Tucson can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all.
Why does the Check Engine light come on on Hyundai Tucson?
Oxygen sensors can change the way that your Tucson’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.
What does an OBDII scanner do on a Tucson?
By using a OBDII scanner you can determine exactly which sensor is bad, and what is wrong with it. Your Tucson’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized.
What is the OBDII code on a Hyundai Tucson?
P0130 is a very common OBDII code that occurs in the Hyundai Tucson. It is typically caused when the Oxygen Sensor voltage is not within normal operating conditions. Typically, the only symptom of P0130 is going to be the service engine soon light.

Can a catalytic converter be repaired without replacing the ECM?
Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. A careful search might reveal exhaust leaks that, when repaired, “restore” catalytic converter function, at least from the point of view of the ECM.
What is the diagnostic code for a catalytic converter?
An illuminated check engine light or malfunction indicator lamp (CEL or MIL) with a catalytic converter diagnostic trouble code (DTC) is the most common catalytic converter problem indicator.
What happens if you replace the catalytic converter?
If you spend $900 or more to replace the catalytic converter, you may discover the check engine light coming on again later. Some mechanics will tell you to try replacing the oxygen sensors first, to see if that solves the problem. There are two of them, one before and one after the catalytic converter.
