You don't even need to jack it up. Any suggestions otherwise?

This page is meant to help you troubleshoot the Nissan Murano P trouble code. A failing oxygen sensor or bad catalytic converter are the most common causes of P Catalyst system efficiency is the percentage of these chemicals removed from the exhaust system. Oxygen sensors measure these pollutants. When the readings from the upstream and downstream oxygen sensors show similar readings not enough pollutants expelled from the exhaust , your vehicle will throw the service engine soon light P This can happen for three reasons:. You can ignore this section if your Murano has an inline engine or if the exhaust manifolds merge into one pipe before the catalytic converter. Typically, the first cylinder is closer to the front of the engine. The bank 2 version of this code is P There are rarely drivability issues associated with P

Firewall side I'm guessing I don't have an equipped garage to do this is at the moment, so if possible, I'd rather replace the O2 and leave it at that Doesn't need anything fancy, any of the generic reader out there should let you reset the CEL and erase the code. That is it. For a better experience, please enable JavaScript in your browser before proceeding.

I could see that being the issue but I'm in Cali so I don't know when that would come around anyways. I read some posts where people say it's a pain because you have to remove the wiper cowl to get to it by the firewall First, check for leaks along the exhaust system — along the pipes, manifold, all the way to the catalytic converter itself.
