The CEL comes on when the PCM detects that the MAP sensor voltage is more than 4.9v for more than 4 secs. rhadiesel 02-11-2008, 04:03 PM so is this a bad idea to keep running it? sound like a big deal i only get the code when at high speeds getting into the gas THE TECH 02-11-2008, 04:30 PM Not sure. Maybe you want to clean the MAF? rhadiesel 02-11-2008, 07:24 PM what do you clean it with??? BHoward6.6 02-11-2008, 07:46 PM MAF cleaner, what else?:D THE TECH 02-11-2008, 09:14 PM MAF cleaner, what else?:D Funny but true. CRC makes a MAF cleaner. If you can't find that, then use a non-chlorinated brake cleaner or electrical parts cleaner. rhadiesel 02-11-2008, 11:04 PM so start with that to fix the problem you think Twister773 02-11-2008, 11:57 PM efi tune...im gonna say its the tuning...i had a tune that set it too...can always just program it not to come up | ||
