What causes the P0158 code on a Jeep Wrangler?
Here are the most common issues that cause the P0158 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 P0158 is triggering your service engine soon light.
What happens when an oxygen sensor goes bad in a Jeep Wrangler?
More often than not, when an oxygen sensor in your Wrangler 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.
What does the p0058 code on the oxygen sensor mean?
What the P0058 code means. When this code is stored in the powertrain control module it means that the heater control circuit in the oxygen sensor after the catalytic converter on the cylinder bank not containing cylinder one has higher voltage than expected.
What is the OBDII code on a Jeep Wrangler?
P0158 is an OBDII code that occurs in many vehicles, including the Jeep Wrangler. The code is triggered when: The voltage at the O2 sensor remains above threshold for 20 seconds or more; Voltage to the sensor is to high (wiring problem, think short) Bad O2 sensor itself; There are also some less likely problems that can cause P0158.

There are also some less likely problems that can cause P0158. We’ll discuss them below. Bank 2 is the side of the engine with the second cylinder in the firing order. Sensor 2 is downstream of the catalytic converter. Here’s a pretty helpful video from on diagnosing the code:

Why is the O2 sensor on my Dodge Ram bad?
Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0158 is triggering your service engine soon light. Although it is a temptation to replace it right away, it wouldn’t hurt to check out the wiring harness around it beforehand. See directly below. They are relatively affordable at Autozone or Amazon.
