Stormtrooper Code - 401 (Help?)

[yondermeister88]

I have a 2003 PR5 with 95,000 and need some help troubleshooting a code I keep getting.

P0401 - http://www.obd-codes.com/p0401

I regularly remove, clean and grease my EGR valve which I have had problems with before. That has been the culprit of misfiring and a poor idle.

I am unsure of where to continue troubleshooting. I can't drive for more than 20min before it throws the code again. I do not sense any symptoms that would suggest there is something wrong.

Any help would be greatly appreciated! Cheers

Check your vac line going to the MAP sensor, as well as proper operation of the solenoid that is in line with the MAP sensor. It is on the passenger side of the engine bay near the firewall. This monitors manifold vacuum and can sense the minor change in vacuum from the egr opening or closing.

Thanks!

I will check that tonight, and let you know what I come up with.

After way too much investigation....Turns out it was a faulty connection on the plug for the ERG valve.

Thanks for the Direction though
