I've unplugged the dreaded DPF killing EGR valve, but now the CEL light is on all the time. I've heard that certain code readers can also turn the CEL off, but that the CEL will soon come back on again...
Short of plugging-back in again the EGR harness, is there a scanner that will keep the CEL light off with the EGR unplugged??
Any scanner should, with ignition in the run position engine off, clear codes and then start, but do you really want to do that every time you start the truck? Not to mention it might mask a real fault from triggering the CEL.

If you are just wanting to read the codes, you can do that with just the ignition key.
Turn the ignition on (without starting the engine) and off three times quickly (leaving it on the last time) and write down the numbers that scroll across where your odometer is. You can then use this forum to find out what the codes stand for.
