| Post subject: | CEL without P-code? |
Hi everyone. My 05 KJ Sport just started showing me its CEL. The Odo Reset + Ignition On trick isn't showing me a code. Has anyone seen a CEL with no code? Also, in either 4 Hi or 4 Lo, the "Part Time" and "4 LO" indicators aren't showing (sometimes briefly), though the lights come on during the dash diagnostic. So would a loose transfer case position sensor plug cause a CEL? I crawled under, found and wiggled the plug at the transfer case, but no change. Where's the other end of that wire so I can wiggle it, too? Thanks in advance! Eric Edit: My mistake. I just tried the On-Off-On-Off-On trick, which returned three codes, P0456, P0839, and P0837. At least now I have something to work with. These codes aren't on any of the OBDII code lists I've found. Googling the codes helps a little: P0456: Evap sys leak or maybe gas cap. P0839: Transfer case position switch P0837: Transfer case position switch This list: http://www.autoxuga.net/cursos/averiasp.htm is more complete than other lists of ODBII codes I've seen, but I had to use Google to translate it: http://translate.google.com/translate?u=http%3A%2F%2Fwww.autoxuga.net%2Fcursos%2Faveriasp.htm&langpair=es%7Cen&hl=en&ie=UTF-8&oe=UTF-8&prev=%2Flanguage_tools At least now I know where to start looking. If anyone has any other input on these codes, I'd appreciate it! Thanks, Eric |

That transfer case switch is kinda common. Its nothing to worry about unless you like the lights showing up. Should be easy to change out but Idk about the $$. |

Thanks Jeepjeepster. That's good to know. Interesting that the onboard computer knows and cares about the transfer case position switch. My only concern about that is that when you're in 4 LO, the onboard computer ups the idle speed (which kind of annoyed me anyhow) and automatically slows you going down a steep hill (doesn't it? Seems like it did to me, but maybe that's just a result of using Low range). In other related news, the CEL has gone out. Perhaps it was just the gas cap after all. I also changed the air filter, since I had a new one sitting around. So couldn't say what that was about, but I guess the transfer case switch doesn't trigger the CEL, even though the onboard computer knows about it. Thanks! PS, I looked up the parts. To get a new switch and its O ring would be about $70 for the parts. Doing the work seems to me just to be a matter of doing the under-car yoga and not letting dirt get inside the transfer case. |
