Talking p0158 code, oxygen sensor short?

Done a bit of searching, but haven't found a whole lot around the p0158 code I'm getting.

The code itself is a high voltage reading related to the o2 sensor (thanks to those who put in the effort to list the codes). But I haven't come across anyone who's diagnosed what's actually causing the problem.

Anyone have experience with that code?

THanks in advance.
Bob

Hey Bob, Welcome to the site. I have never had to deal with that code but my first guess would be a failing o2 sensor. What year is the truck?

Code P0158: "Oxygen sensor input voltage maintained above the normal operating range"

You' re definitely right their. I would replace the sensor and hope its that: otherwise your air/fuel mixture is too oxygen rich. No good.

Without doing any testing (using obdII) your possible problems are:
O2 sensor
O2 secsor circuit short
Or
Replace and program the Powertrain Control Module

Hope it's the O2 sensor for ya ;-)

Thanks

Thanks all. Checked for all things obvious (wires, etc.), but didn't find anything. THe warning/code actually went away, but I'm a bit concerned. Probably just replace the sensor as a precaution.

It's a 2003 Durango.

Thanks again for all the responses.
