Jeffrey Baker Posted July 2, 2013 Share Posted July 2, 2013 For SPN1127It says in the book that boost pressure is too low in the turbo charger and likely sources are air leaks in the hoses, pipes or cooler or the EGR failureFor SPN102Deals with the Intake Manufold Pressure - Pressure sensor output is too low. Likely causes are a fualty harness, intake manifold pressure sensor or inlet air leakageI am not very mechanically inclined so that is all I have for you coming from their Codes book Quote Link to comment https://www.bigmacktrucks.com/topic/31644-engine-fault-codes-2013-granite/#findComment-192249 Share on other sites More sharing options...
