CEL with straight piped exhaust

BIGJED · #1 (**permalink**) 07-18-2009, 04:25 PM

Just straight piped my truck, now I have a CEL. I havent had
the code read yet, but if the exhaust is causing the light is
there anyway to prevent it. without putting muffler or cat
back on. Any advice appreciated.

I've never heard of an exhaust change causing a CEL...Maybe another sensor was bumped? Or maybe its pure coincidence, good luck!

Just got the code read,was coincidental I guess. The code was
P2285,ICP sensor.

Did you let it warm up before you got on it. My 05 excursion will show a icp code if I don't let it warm up.

The light did come on shortly after start up,so that is a possibility.
Had the dealership check it out, they replaced ICP but also
reprogrammed PCM which I didnt understand, but everything
seems to be working fine now
