Is the Jeep Wrangler TJ sensitive to oxygen?
Pay close attention to this one so you can do it once and do it right! The Jeep Wrangler TJ is extremely sensitive to all oxygen sensors other than NGK / NTK. Bosch O2 sensors and all the others (including the crappy Chinese brands you’ll buy at your local auto part store) are very well documented as not working properly with our TJs.
What happens when an oxygen sensor goes bad?
When an O2 (oxygen) sensor go bad, it’ll cause your Jeep Wrangler‘s engine to run less efficiently. Your Wrangler can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all. Often enough, the only sign of the problem at all is the service engine soon light being on.
What are the sensor codes for a Jeep Wrangler?

How can I tell if my O2 sensors are bad?
Bad O2 Sensor Symptoms Foul Odor. One of the first symptoms that indicates a bad oxygen sensor is a foul-smelling and strong order that will come from the exhaust. Check Engine Light. As described earlier, this orange flashing light might be the first symptom you notice. Engine’s Efficiency. Fuel Consumption. Emission Test Failure.
What will a bad O2 sensor do?
A bad oxygen sensor can impede the air/fuel mixture of an engine or interfere with the engine combustion, both of which can cause an engine to miss, or run irregularly.
When to replace O2 sensors?
Car manufacturers recommend replacing the O 2 sensor about every five years (one- and two-wire sensors) or 10 years (three- and four-wire sensors). However, silicon or carbon soot may cover an oxygen sensor due to a car repair or engine performance problems.
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.

Can a bad O2 sensor cause a misfire?
Without the proper air/fuel mixture, your engine won’t run as smoothly as it should. 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.

How do you replace an exhaust sensor in a Jeep Wrangler?
Turn the sensor counter-clockwise to remove it from the exhaust. Discard the old sensor. Install the two new sensors into the threaded sections of the exhaust where you removed the old ones from. The two sensors used by Jeep are identical, so either one is fine in each hole.
What is the resistance of an O2 sensor?
At ambient temperatures around 70°F, the resistance of the heating element is approximately 4.5 ohms. As the sensor’s temperature increases, resistance in the heater element increases.
How many O2 sensors does a Jeep Wrangler have?
If you have three cats, two small ones off the manifold and a main cat by the t-case skid then you have 4 O2 sensors. 2000 california models, and all 2001-2006 are like this. if you only have one cat by the t-case skid then you have 2 O2 sensors. only 97-99, and some 2000’s are like this. Thanks for the quick replies.
How to test if the O2 sensors are good or faulty?
O2 sensors for the Jeep Wrangler. How to test if they are good or faulty. O2 sensors basically sniffs the exhaust and outputs voltage between 0 and 1 volt indicating how much oxygen is in the exhaust. The PCM reads the output voltage from the O2 sensor to adjust the rich/lean condition of the fuel mixture.
Is there a heater in the O2 sensor?
I just checked both O2 sensors , both wire connectors are all in tact , no damage. There is a ‘heater’ in the O2 Sensor. Just replace the O2 sensors. The O2 sensor uses a Positive Thermal Co-efficient (PTC) heater element. As temperature increases, resistance increases.
What is the catalytic converter code on a Jeep Wrangler?
Your Jeep Wrangler leaves the factory with a catalytic converter. It can run into problems over the normal life of the vehicle, and is often accompanied by OBDII code P0420. Below we’ll cover the location, price, and symptoms of a bad torque converter in your Wrangler.
How do you replace an oxygen sensor in a Jeep Wrangler?
Install the two new sensors into the threaded sections of the exhaust where you removed the old ones from. The two sensors used by Jeep are identical, so either one is fine in each hole. Tighten the sensors with an oxygen sensor socket and a torque wrench to 22 foot-pounds.
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.
What does rear O2 sensor on pirate 4×4 do?
The rear o2 sensors are there to check that the rest of the system is operating properly, mainly the front 02s and the fuel inj. By figuring out what voltage output the rear 02 puts out when all is working right-all that’s required is to supply that voltage back to the computer.
Can a torque wrench tighten an oxygen sensor?
Tighten the sensors with an oxygen sensor socket and a torque wrench to 22 foot-pounds. Do not use thread locker, anti-seize or any other compound on the threads of the sensor.
Why does my check engine light come on on my Jeep Wrangler?
Oxygen sensors can change the way that your Wrangler’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.

Where are the O2 sensors located on a Jeep Wrangler?
If you had 4 O2 sensors, you would have a Bank 2. Your O2 sensors should be located before the cat, and one in or after the cat. First one (upstream) determines A/F ratio and makes the engine run, the downstream measures the “health” of the cat. I unplugged the O2 sensor for now, and never noticed a big change in the jeep.
At ambient temperatures around 70°F, the resistance of the heating element is approximately 4.5 ohms. As the sensor’s temperature increases, resistance in the heater element increases.

When they fail, your Jeep’s onboard computer system is forced to guess the correct mixture, leading to irregular performance. Fortunately, with Same Day Store Pickup (in most cases) and our helpful Loan-a-Tool Program, AutoZone is on hand to get you everything you need to keep your Jeep Liberty in working order.
How to install O2 sensors on a Jeep Wrangler?
When installing new O2 sensors, be certain to use some anti-seize on the threads of the new O2 sensors! This is important, and will save you a huge headache should you ever need to remove them in the future. In addition, a O2 sensor socket will greatly aide in the installation and removal of O2 sensors. I recommend this one.
