Hello

I have a 2005 jag x type that always seems to act up in wet weather. It snowed here yesterday and on a short drive I got the gearbox fault message with a red light, the battery light and a check engine light.

The codes are P0915, P1642 and P0443, any help om this subject would be greatly appreciated

Regards
Jim

 

Jim,

Saw your Intro post and it sounds like you need this info fast. I've zero direct knowledge on X-Type but can give you the code details from the Jaguar DTC Manual:

P0443: EVAP canister purge valve circuit malfunction
P0915: J Gate signal failure
P1642: CAN circuit malfunction

Until you have 10 posts and 3 days forum membership, you can't download files from the forum. No point in me putting an attachment here because you can't access it yet so I've put the full DTC details for these three codes on my MediaFire account. You can download this PDF from here:

Copy and paste this link into a new browser page. No registration requirement (and no charges!) to download from MediaFire.

Hope it gets you started identifying the issues and experienced X-Type owners will pitch in with further information.

You won't find much at all on the P0915, so I'll give you my story.

I started getting this same code shortly after I bought my X. It was definitely more prevalent in warm/humid weather, and I know there was a secondary code too which could have been a P1642, I can't remember exactly. I was resetting my OBD codes every 2 - 3 days during this period.

I went down so many paths to fix this, tore apart the J-gate and tested the switches, tested the hall effect sensor, thought maybe cell phone could be interfering with the 5-to-4 hall effect sensor so tried keeping it away from the shifter, readjusted the linkages per JTIS, pulled the TCM and inspected all the connections, ziploc baggied the unit anyway. At some point during all that I went crazy enough that I made the error message my avatar here.

It wasn't until I started pinning out the harness from the J-gate to the TCM (and elsewhere) that I discovered a wire that was being pinched by the tilt steering column. All I did was move the steering column up a couple of inches and I got continuity again. I spliced the break and have not seen the Gearbox Fault since, about 15 months.

At first I was mad at the dealer for selling me a car that very clearly couldn't go more than 25 miles between CEL resets with this code, but then I realized it was most likely my fault when I bought the car. What's one of the first things you do when you buy a new car? Play with all the controls and get everything the way you like it, right? I am sure that as soon as I moved the steering column, probably on my very first drive from home, I caused the problem myself.

 

Hey I see you have had the same code I have! I have been driving with the P0915 code on as well as the red exclamation point light! Car runs beautifully just light will not go away many places have said the code doesn't exist in 03 x-types so wanted to get some of your opinions! Don't wanna go to the dealer and say its a "dummy code" for $129 an hour! Would greatly appreciate the input!
