vr8520 Posted July 26, 2014 Share Posted July 26, 2014 06 cxn613 has an active 4-5 code. From looking on the internet, it's a turbocharger waste gate problem? Anybody had this problem before? Any input is appreciated! Quote Link to comment https://www.bigmacktrucks.com/topic/36470-engine-code-4-5/ Share on other sites More sharing options...
Macktech689 Posted July 26, 2014 Share Posted July 26, 2014 The 4-5 blink code is pretty a common problem, there are several things that will cause it both electrical or mechanical. Finding the failure mode identifier is the first thing I would do, you will need to use Mack diagnostic software to determine the FMI.

vr8520 Posted July 26, 2014 Author Share Posted July 26, 2014 Thanks macktech689! The trouble I'm having is it's very weak while pulling any kind of load. I'm not a mechanic by any account but it seems like it takes a few seconds for the turbo to pick up and it still isn't pulling like a 410 should. The Mack before the this one only had a 350 and it would handle the same loads like a champ.

Macktech689 Posted July 27, 2014 Share Posted July 27, 2014 The 4-5 will always cause low power because the turbo is not functioning correctly and the boost pressure is low.

vr8520 Posted July 27, 2014 Author Share Posted July 27, 2014 Thanks again macktech689! I guess I'll bite the bullet and get the checkbook ready and head for the local Mack dealership.
