asylum Posted August 2, 2016 Share Posted August 2, 2016 I have a 2004 Mack Vision that is throwing a code 3-1 which comes up to exhaust temperature. Will this cause the truck to cut back on rpm and loose power. It will only do this once in a while otherwise it runs good with no problems but when it does it wont hardly move off the spot. It makes no difference hot or cold engine temp. Quote Link to comment https://www.bigmacktrucks.com/topic/46296-mack-vision-code-3-1/ Share on other sites More sharing options...
steeler Posted August 3, 2016 Share Posted August 3, 2016 Yes, if the derate is turned on in the programming then it will cut power. Quote Link to comment https://www.bigmacktrucks.com/topic/46296-mack-vision-code-3-1/#findComment-341180 Share on other sites More sharing options...
