What happens when the oxygen sensor goes bad on a Jeep Liberty?
More often than not, when an oxygen sensor in your Liberty 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.
Why does the Check Engine light come on on Jeep Liberty?
Oxygen sensors can change the way that your Liberty’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.
How to relearn the TPMS sensors on a jeep?
Just put the jeep through its TPMS relearn mode and train the sensors using the magnet. Also if your sensors can not be triggered by the magnet have the shop put the truck through its relearn cycle and have the shop trigger the sensors according to the pattern on the EVIC. Click to expand… No magnet, this is the 05+ version. And no evic.
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.
Is there an oxygen sensor on a Jeep Liberty?
Your Liberty packs a lot of power into an efficient off-road design. When that power dips or starts coming and going at odd times, that indicates a problem with one of your sensors. A quick computer diagnostic can tell you whether it’s the Jeep Liberty oxygen sensor or a related component.

Can a faulty oxygen sensor be replaced at AutoZone?
You can easily swap out your faulty oxygen sensor with a new one at AutoZone. 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 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.
Are there any safety ratings for the Jeep Liberty?
According to The Car Connection, while Jeep was producing the Liberty, the safety ratings from both the NHTSA and the IIHS were good at first. However, the NHTSA did not re-test the Liberty after they updated their safety criteria and scoring system.
What happens when your ECM goes bad on a Jeep Liberty?
When the ECM it self goes bad it can be extra challenging to determine that it is at fault. Your Liberty does run self diagnostic checks, so it is worth it to check if there is any error code related to the ECM/PCM currently stored. You very well get one such as P0606 (processor fault).
Are there any problems with a 2002 Jeep Liberty?
One of the doors won’t open from the inside or out and the window won’t open on the other. Minor considering the overall reliability. She still looks good on the outside. Driver side carpet and upholstery are very worn, but that is to be expected.
Oxygen sensors can change the way that your Liberty’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 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.
Is the Jeep Liberty part time or 4×4?
With no snow tires and basically all in part time 4×4 it handled flawlessly. Everything was perfect except for some creak in the driver door but hey. I didn’t much care for the car but time and time again it blows me away. Infinity speakers, roomy and stylish inside and out. and Reliable.
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.
Can a check engine light be an oxygen sensor?
It seems as though the check engine light and O2 Sensor codes have always gone hand in hand. I can’t even begin to tell you how many perfectly good sensors I’ve seen replaced for a rich/lean code, or as a cure to a service engine light that comes and goes. Fact is, when oxygen sensors were first being used, they did tend to fail.
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”.
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.
Are there any codes for an oxygen sensor?
There are a large number of codes relating to oxygen sensor faults. There are also a lot of faults that are often incorrectly thought to be caused by a bad oxygen sensor (also referred to as an O2 Sensor). The O2 codes relating to circuit faults can be tested fairly easily.
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.
Can a bad O2 sensor cause incorrect readings?
A leak in the exhaust system before the O2 sensor will also cause incorrect readings. And always check for after- market modifications. These can throw a wrench into the works! The only other possibilities (however unlikely), are wiring issues, computer concerns or a bad O2 sensor!
