Hey DFlinstone,
Cheers for that. I have a '99 TD. The part I ordered was for a '99 4.0 ltr petrol.

The photos don't show it but there are three (moulded) wires into the actual magnet/sensor but only two pins.

I had half a thought to butcher/solder the new sensor onto the existing TD CPS connector and plug it in, but I figure that I'll wait for the dealerships to open (all local dealerships' parts departments are closed on the weekend - here in AUS) and get a price.
Monday again is a public holiday here, so I'll call them on Tuesday and see what the go is.

Regarding the metal bracket, it is definitely untampered with - it's moulded into the sensor.
- I was thinking if I cut it up I could flip it around and epoxy it back together. It would bolt into the bellhousing 'as is' but that would have the effect of moving the sensor further away from the flywheel.. Which I imagine is undesirable?

In the previous post there is a link to a French website that has the CPS for the turbo diesel listed; it looks identical to the one I have etc so suggests untampered with etc.

As an aside, I cleaned everything with electrical/contact cleaner and reassembled and redid all of the grounds & battery terminals (dash now reads ~14.2V when running - was bang on 14V before).
Drove the car like I was trying to make it stall and could not (for a bit). After about a half hour when it was super warmed up, I could drive in a manner to make it stall ( as described in the initial post by the OP).
This suggests (from what I've read) that it is likely to be the CPS as it malfunctions (randomly) when the engine/components is/are nice and warm..?

I'll stop rambling and post back any useful info that I get once I speak to dealership and hopefully install the new & correct CPS and *hopefully* resolve my issues. I'm a bit uncertain that this will fix my issues as it turns out that the CPS that I pulled out is a 2nd hand replacement (there was a sticker on it identifying it as thus). This makes me think perhaps this was an issue previously (I only recently bought the car). Still I think I will replace the obvious culprit (with a brand new sensor) and rule it out as a possibility then if issues persist I'll concentrate on fuel system.

Cheers :-)

Sorry, just wanted to add - with the TD motor, the block is much shorter so you can actually see the CPS from the engine bay.

I found that if I removed the fuel filter I could stick an arm through the space and reach down to the bell housing to feel for the bolt heads and guide my left hand which was reaching down from above between motor and firewall.

Doing this I could undo the bolts easily and quickly using an 11mm ring spanner.

I tried the socket extension method first and was able to get one bolt out, but could not get a socket onto the second bolt as there was a hose in the way (seems to be the transmission breather hose that has a plastic clip to hold it in place right near the CPS clip. - this can be moved\unclipped from above too.

Hope this helps. Took me a good hour to work out I was in the right spot and get first bolt undone using sockets. Took me another 30 mins to work out that I could not usefully get a socket onto the second bolt. Once I realised I could get to everything from above it took 15 mins to remove everything and once cleaned up about 15 mins to put it all back together..

Here you can see the CPS connector and the breather hose. Both have little black prong things that fit into holes to keep them in place, just wiggle them out with your hand, teensy bit of force required.
Cheers.
top left is the CPS connector, bottom right is the CPS sensor, you can see the two bolts to be removed.

it's not a good picture but just shows that I temporarily unbolted the fuel filter to push it out of the way to leave a gap to stick my hand/arm through (yes it's a non genuine Racor filter and assembly - had some Nissan job there when I bought it..) all fuel lines can remain attached so only takes a minute.


Just illustrating that the metal bits are inverse..

For once I am glad I have been a little lazy working on my Jeep, and STILL haven't gotten around ordering a replacement CPS!
I was all set to order the 4 ltr petrol one.

Many thanks for all the incredibly useful information you supplied in your earlier posts in this thread. I read the other forum listing the TD engine with much interest!

Whenever you pulled out the CPS. Did you find the tip of the sensor to be very dirty? If so, it might be worth cleaning and placing back in?

Your photos were very helpful too! I'll probably move the fuel-filter out of the way, and do the same. However, if it is really a 30 min + job, I might just give cleaning the sensor a go later today (Time to stop being lazy!)

Will update later.

Thanks again for the effort you put in to post on this thread!

Geez! 120 Euro's.. That's 3/4 times as dear as the petrol version!

Cheezel

Unsure if I updated the thread, but yes I cleaned it before putting back together. Photos are how it was 'pre-clean'. Not much dust, it looked a little brittle/heat affected perhaps..?
I used electrical contact cleaner and sprayed a bunch around where the sensor sits too but expect that to be futile as any dust/gunk would likely get circulated by the flywheel itself.

Anywho, still stalls after the clean, curious to know how you go with the bolts. I'm 6'4" and could just reach it all with my feet on the ground. If you can't reach it then might need a knee on the radiator/battery and the other on the rocker cover :-)

This is a pic of the new vs uncleaned sensor:



Cheers.

FYI. I called the local jeep dealer whom advised none in stock and apparently none at any of the dealers in the country. Thus have to get from jeep US which will take 5 weeks and cost $AUD278 which is about $270US.
Seems ridiculous.

I'm thinking I might cut up the petrol one that I ordered ($22) flip the bracket epoxy it back on and swap end connectors (cut and solder). If it does not work then will solder the original one back together and order a new replacement..

If you find them cheaper anywhere please keep me posted!

Cheers.

So, I've still not replaced my CPS as I really think its good - this is based on it being replaced already as previously mentioned. I just realised that Chrysler voyagers from about 95 to 2000 with the 2.5td motor are also the same as the xj 2.5 TD jeeps - eg vmmotori.

Read this thread here: http://www.chryslerforum.com/forum/c...voyager-10937/

And seemingly the same thread on a different forum here: http://www.honestjohn.co.uk/forum/po...ex.htm?t=87373

I'm going to look into the 'fuel quantity actuator' and see if this can be adjusted or if it needs to be replaced. The pump is Bosch so I'll see what I can dig up. Cheers.

Hi Cheezel,

A bit of luck for the two of us?
For the first time since I started looking, eBay is showing a seller with the correct TD CPS (56027963). He has two of them for £20.- per CPS + shipping. Granted, they are second-hand, but at that price it's worth trying.
Should you want one as well, then I'd be happy to purchase one for you too and ship it to you if the seller won't ship to you.
Here's the link:
http://www.ebay.co.uk/itm/Jeep-Chero...#ht_1278wt_967
Please note there's only one left since I purchased one of them ;-)

Hi aakkermans
I always read you posts with interest and was hoping you may be able to help me with a problem I have with my XJ 2000 VM 2.5 tdi B59 engine. It appears to have suddenly gone into "limp" mode. Turbo boosts till 2000rpm then no more boost. It will continue to rev but as if no turbo. I have had a boost gauge on it (at the turbo) 15psi. Filters are new, no air leaks (starts well). I had it to a Jeep dealer, but no fault codes. I did try to start it with the main plug (behind the fuel filter) disconnected after work on the A/C. I am finding it impossible to find any info on this system from Jeep or Bosch. could you or anyone out there help me on this.
Many thanks
David

Cheezel

Sounds like limp mode for sure. I believe you may have a cooked #1 injector. There is a good XJ 2.5 VMMotori TD community at http://www.ausjeepoffroad.com , plenty of discussion around this, and on the parts sticky people often purchase them from Lithuania (very, very expensive in AUS otherwise).. Best to start a new thread there

Cheezel

Excellent - thanks for that. I'm going to be a fence sitter for the moment though as believe that my issue will be the injection pump, so when you get and install yours please keep me posted

aakkermans

Hi Cheezel,

Thanks for the reply to Rustic's post. Not sure why he referred to me, as I'm certainly not qualified to help him. (I actually have a similar problem with limp-mode, but only intermittently... must check the Aus forum on that, haha)

Regarding the CPS, yeah, I'll (hopefully) be able to report back after the weekend...

Regards,

Anthonio

Cheezel

Hey Anthonio,

Wondering how the change of sensor went?

Cheers :-)

aakkermans

Lol... It didn't...

Got lost in the post (Promptly refunded by seller)
So, now I'm waiting for a new chance on eBay, or enough spare money to buy one from that French web-site you posted...

Just my luck!
