jimbo@2006 Report post Posted April 4, 2014 Hey Gang, Anyone know how to get the fault codes on my 06 cat7 engine? Tried the cruise control trick - key in on position engine off, cruise in off position, press set button until codes come on and nothing happened. Reason I ask is I had check engine light come on while pulling a grade. Thanks Share this post Link to post Share on other sites

Assume you have checked the fuel filter(s), as this is where a clogged fuel filter will first exhibit symptoms. Also, check the air filter minder reading to make sure you don't have an intake restriction. Share this post Link to post Share on other sites
