EVAP system in 2005 Nissan xterra Sign In
I have a 2005 Nissan Exterra, the check engine light went on. I got a code for the emission control valve C short. What are the steps in solving this myself before bringing it in to the shop?

What is the trouble code number? Do you have a volt meter and understand the theory of electrical circuits (including computer circuits and bias voltage) and how to diagnose them?

P0455 doesn't have to do with any valve circuit being shorted.

P0455 is a large leak code. Means there is a big leak in the system between the fuel tank and EVAP canister purge volume control solenoid valve.

You need to find a shop that has an EVAP tester/smoke machine to find the leak.

Hello,

Thx, your right I have, I looked at code wrong..so could this be a muffler issue or is it internal? I want to diagnose problem as much as possible before calling a mechanic..
