Hello everyone, I'm new here and I hope you all can help me out a bit:)

I'll give you the specs first

1999, v6, 4x4, ext cab long bed

My truck is throwing 3 codes at me and I'm hoping you guys can help me fix this problem.

I only have 69003 miles on the clock

First is P0325, knock sensor of course...I decided to buy a new one and see how long it lasts, if it goes bad again I might just do the bypass mod.

Second is P0400, says an error with exhaust gas recirculation flow, how do I go about fixing this?

Third is P1444, Canister purge volume control solenoid valve probable cause, again how do I go about fixing this?

any help is greatly appreciated

thanks!

Does the truck have driveability problems?

Inspect the systems that are indicated as having faults. Look for loose, damaged, or broken hose and electrical connections.

I'd reset the light and see if it returns. Make note of the conditions under which it returns.

Get a manual, e.g. Haynes or Chiltons (Nissan is best), and perform any additional inspections or measurements that it advises for the affected systems.
