Baja Stories
 

Just about to roll 190k on the 08. Closing in on the 200k mark. Since covid I've had even more free time to roam Baja and on this particular adventure, I get the 02 sensor check engine light every 600 miles now. What is weird is that it always comes with a C1405 - Transfer Case Range Position Sensor Circuit High. Why do both of these codes come on at the same time? They would seem like they have nothing to do with each other. Transfer case is covered under lifetime power train and I would like to get it to the dealer with the code but I also have the super chips 87 octane tune running. Can I reprogram to stock settings while the check engine light is on? or will it clear it anyway once I restore it back to stock?

Drove about 2 hours off the main road to check some good surf spots last weekend. Instrument cluster says I'm in drive, Transmission shifter says im in Park. Cant move it out of park. Climb underneath and notice the linkage was off and just laying there. Pushed it up and back onto the transmission and relieved the heart attack I was having in the middle of nowhere by myself. lol I'm going to climb underneath tomorrow and take a closer look and do a tire rotation and hose down the undercarriage. Is there anything I should be looking for that could be broken on this? I didn't really look at it when I re connected it I was just thankful to get my truck outta there and back to base camp.https://cimg5.ibsrv.net/gimg/www.jk-...ba486f4e7b.jpg

Ok so same problem tonight in a parking lot. This time the bushing that is inside the cable that hooks to the pin on the transmission is missing. I remember buying a plastic bushing as a spare but I think it was for the transfer case and not the transmission.

First I would love to have this covered under lifetime powertrain but I don't think external parts of the tranny are covered? Would this be covered or is it dealer discretion since its the cable?

2. When I reset the superchips to stock tune it deleted the codes so that answers that question for anyone wondering.

3. Any ideas about the C1405 - Transfer Case Range Position Sensor Circuit High?

Wanted to get that post up since Im headed for another adventure on Sunday. Would this be the cable for a full replacement? $65 on rock but its a doorman? or is there a $10 bushing. The one I got is for the transfer case and it was $3 from rock before they sold out. I've seen some you tube videos with them using some kits from AutoZone and such. Im willing to bet there isn't a mopar part number for the bushing but rather you have to do the entire cable assembly.

Below are the possible causes from the manual. First thing I'd try is removing the connector from the transfer case sensor, inspect the wires, and then clean it with some plastic safe 'tronics cleaner. That fist possible cause (below) could be simply a bad connection at that connector. It must be intermittent otherwise the dash indicators for 4WD would not work.

Regarding the O2 sensor code coincidence, maybe an intermittent C1405 DTC doesn't turn on the CEL, so the only time it gets noticed is when the CEL turns on for another reason???

Mt. T always the electronic expert! Thank you. The transfer case is pretty small so Im assuming there is only one sensor going to it? or is that sensor actually on the transmission before? It makes "sense" (had to) too because when I shift into 4x4 sometimes it takes 20 seconds or 20 feet to kick the light on. I can feel being in 4x4 but its a delay popping it up on the dash. TC is covered under warranty but I'd rather not bring it to them if I can change a simple sensor.

There is only one sensor on the tcase, it's on your driver's side, up above the shift linkage. There's a large nut with a connector dropping into it. I don't recall if there's a red safety catch on that switch or not.

Anyone with any ideas on the transmission shifter linkage bushing? I think I have a good game plan set for the T case.

Those plastic bushings are known to fail. I had one go on the tcase shifter and the dealer wanted to sell me the whole linkage instead of just the bushing. I've seen online where folks drill a hole in the end of the shaft and run a cotter key through it to keep the linkage in place, but I've not been brave enough to attempt that.

Ok I'm gonna look around for a bushing and I guess at worst case I can get a new cable and install that. It doesn't look too difficult. Would rather just pop in a plastic bushing however and be done with it.

I'm going with this one and I will report back with the results.
