Jim Warman Posted July 10, 2011 Share Posted July 10, 2011 I have one that has, amongst several other concerns... NOx sensor, DEF heater, P0405 included.... a problem with hoses going to the EGR cooler bypass actuator and solenoid. The rubber elbows at the ends are all swollen and don't grip the nipples (for some reason that didn't sound real right). Nothing obvious under the hood...

Brad Clayton Posted July 10, 2011 Share Posted July 10, 2011 Has a concerned customer been under the hood degreasing the engine? Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted July 10, 2011 Author Share Posted July 10, 2011 This is a fleet truck (drilling rig tool bit salesman) - his worst sin is visiting Kwikee-Loob. I would doubt he even knows how to open the hood. Quote Link to comment Share on other sites More sharing options...
sweeneynathan Posted August 9, 2011 Share Posted August 9, 2011 Ive gotten 3 trucks like that so far and they all turned out to just be a really clogged air filter hope that helps. Quote Link to comment Share on other sites More sharing options...
