Where is the O2 sensor on a Jeep Liberty?
If you find the code you can determine the problem location. Then go to the store and buy a O2 sensor tool (any auto store), call up your dealership/auto shop, and have them order you the exact O2 sensor that you found was the problem based off the code. There is a O2 sensor located right under the drivers area.
Can you replace O2 sensor and still get check engine light on?
Replace O2 Sensor and still get Check Engine Light On. Replaced O2 Sensor and still get Check Engine Light On. 2 different shops did reads on my check engine light codes, I even paid $100 for one of them to do a full test of all sensors to identify which one was bad. Their diagnose was code P0141, oxygen sensor heater, o2 sensor had to be replaced.
What should the resistance of the IAT sensor be?
Now, to test the IAT sensor with a multimeter, you should measure the resistance of the sensor. If the multimeter shows a reading of 0 to 47 Ohms, then you have a problem with the sensor. The only thing remaining is to check for a circuit malfunction in the IAT sensor.
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 does the oxygen sensor in Liberty work?
Liberty oxygen sensors work to regulate the amount of O2 coming into the engine, matching the amount to the fuel so that you get the most efficient performance possible. When they fail, your Jeep’s onboard computer system is forced to guess the correct mixture, leading to irregular performance.
What causes a bad O2 sensor on a Jeep Liberty?
This is especially true if the mixture ends up too lean. While a rough running engine can be a sign of a bad oxygen sensor, it is often a sign of a misfire as well. Often enough, there won’t be any noticeable signs of a bad oxygen sensor. You’ll go to get an emissions check done, and your Liberty fails the test.
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.
Where can I buy an oxygen sensor for a jeep?

Where is the oxygen sensor in the engine?
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.
Where are the O2 sensors on a Volkswagen Golf?
Sensor 1- Sensor 1 would be the first O2 sensor in the line of sensors starting with the exhaust manifold and making its way back to the exhaust pipe. An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”.
What causes the O2 sensor to come on?
As mentioned, the ECU will ALWAYS tell you which sensor is showing an error, and give you a good idea of what the error is (generally with o2 sensors, they will come on if the voltage is too high or too low for too long of a period of time). Somewhere between being sane and insane!
Where is the downstream O2 sensor located?
The downstream oxygen sensor is located in the exhaust pipe after the catalytic converter. The role of the downstream oxygen sensor is to monitor the working and efficiency of the catalytic converter. There may be one or two oxygen sensors depending on the number of cylinders. The ECU compares the signal from upstream and downstream sensors.
Where is the rear O2 sensor located?
The rear oxygen sensor is located in the front section of the rear catalytic converter. On the 2.2L engine the front (A/F) oxygen sensor is located in the front section of the front catalytic converter. The rear oxygen sensor is located in the rear section of the rear catalytic converter.
What are the signs of failing O2 sensors?
- Reduced gas mileage
- A bad smell like rotten eggs coming from the exhaust
- The check engine light comes on
- You notice that your engine idles roughly
- The vehicle is suddenly hard to start
Where is the oxygen sensor located on the engine?
Oxygen sensors O2 sensors will always be located in the exhaust system. Their function is to sense how much oxygen remains in the exhaust that is flowing out of the engine, and report that information to the vehicle’s engine control computer.
