Brandonros Posted March 12, 2023 I have a 2014 Nissan NV3500 van with a CEL showing codes P0446 and P0447 evap codes. I’ve replaced the evap solenoid and confirmed with 12v that it does open and close as it’s supposed to. I’ve bought a new evap canister, and then replaced the fuel tank filler tube assembly and nothing fixed the code. Finally, I checked the harness connecting to the fuel vent solenoid and found it only outputs 8-9volts and I believe this is not enough voltage to open/close the solenoid. Can you help share a wire diagram or info on if the solenoid gets its voltage directly from the ECU or if it could be a bad ground causing low voltage? Thanks Quote Share this post Link to post Share on other sites

radin2son Posted March 20, 2023 Best bet is to go to Titan forum by googling 2005-16 Titan evap codes. There is a Nissan Titan TSB bulletin for P0448. There may be other evap TSBs as well. Try electrical as well. There are several Titan forums… They are a better resource than NV for engine and transmission issues. The problem with this forum is too few users and reluctance to report ? results. Nothing to do with you being new. Quote Share this post Link to post Share on other sites

I understand and I appreciate it. Quote Share this post Link to post Share on other sites
