What is the OBDII code on a Jeep Wrangler?
P0153 is a common OBDII code that occurs in many vehicles, including the Jeep Wrangler. The code is triggered when there is an issue with the response time from the O2 sensor when switching voltage levels. The Oxygen sensor is responsible for helping the ECM monitor oxygen levels in the exhaust in order to create the ideal air/fuel mixture.
What kind of O2 sensor does a Jeep Wrangler use?
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. In other words, you plug them in and you assume all is well, until you notice your check engine light isn’t going away.
What causes the p0153 code on a Jeep Wrangler?
Here are the most common issues that cause the P0153 code in the Jeep Wrangler. They are presented in order (somewhat) of most to least likely to cause the problem. Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0153 is triggering your service engine soon light.
What is the knock sensor on a Jeep Wrangler TJ?
320 Crankshaft position sensor reference signal cannot be found while the engine is cranking. 325 Knock sensor (#1) signal is wrong. 330 Knock sensor (#2) signal is wrong. 350 A coil is drawing too much current. 401 A required change in air/fuel mixture was not detected during diagnostic test.
Where are the oxygen sensors on a Jeep Wrangler?
The oxygen or O2 sensors are in the exhaust under the middle of the Jeep, so you will have to lift the entire Jeep to access them effectively. Locate the two O2 sensors in the exhaust system. The first one is near the center of the transmission, and the second is between the resonator and the catalytic converter.

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.
Here are the most common issues that cause the P0153 code in the Jeep Wrangler. They are presented in order (somewhat) of most to least likely to cause the problem. Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0153 is triggering your service engine soon light.

What to do if your Wrangler oxygen sensor is not working?
It is possible to diagnose the P0153 with a multimeter. If you use the multimeter, you’ll know whether or not the voltage coming to and from the oxygen sensor is within spec, this can help you determine if it’s your Wrangler’s O2 sensor, or wiring harness that’s the issue.
Where are the O2 sensors on a Jeep Wrangler?
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…

What does O2 sensor code 08-s-05 mean?
The Ford recall number is 08-S-05. Another thing I would like people to understand is the O2 sensor code does not mean it’s time to replace the sensor. It means that it’s time for some diagnosis and repair. If the diagnosis leads to a replacement of an oxygen sensor that is just fine.
How can I check the O2 sensor on my car?
But after you replace the oxygen sensor take a moment and verify that the repair is complete. You can monitor the data stream or perform an O2 sensor test with the very affordable Actron CP 9580 scan tool. For a full review of this scanner visit my auto scanner reviews page.
