Title: Another CRD with issues
Post by: jay140285 on December 20, 2011, 02:03:15 PM
Mother in Laws 2003 WJ CRD is stuck in limp home mode, it has done this a couple of times over the last few months but they ignored it and when turned off and on it was ok.

Now it is in limp home mode max 30mph and wont come out of it.

I am at work so havent had a go at re setting the codes but will do later on my ODBII.

Nat has done the key code finder and got P1130 to do with the 02 sensors, which I cannot see been linked personally but maybe you will say otherwise.

Cheers all.

P1130 is not O2 sensor, it is fuel rail pressure sensor. Does not necessarily mean you have a fault with that sensor as I have the same fault code. But the sensor has checked out ok. Mine had a prob that causes the motor to die on wide open throttle. I think this momentarily causes the rail presure to rise causing that fault code.

Yet to find the real cause....see my post!!

Use below link for fault code meanings for jeeps and wjjeeps.com for loads of WJ info

Got that link saved on my phone!!

But couldn't see P1130 so googled it.

Yes I have seen your post, does the CRD have a Throttle position sensor?

I only ask as I had mine (V8) failed and it would cut out as yours is?

Its due a service Rob, would that cause it to be in limp home mode?

does it need to go to Jeep?

I mate has a full blown diagnostic reader at his garage, would that read as it whether its this or something else?

Surprising really, in my case the gearbox wasn't talking properly with the rest of the truck.

Two coffee's, a car wash, scan & download for £32 squids.

Wolvohampton Jeep want £95 + vat!!!!
Title: Re: Another CRD with issues
Post by: tedthefed on December 20, 2011, 05:13:40 PM
Had that problem with mine earlier this year and it turned out to need a Auto Gearbox ECU unit.  At friends garage used the DRB unit and then tried another ECU from another car prior to putting the new one on worked since , but dont tell the jeep .

Title: Re: Another CRD with issues
Post by: jay140285 on December 20, 2011, 06:15:16 PM
Going to get it booked in for Mother in law at wolvo as she cannot drive it much further at 30mph.
Title: Re: Another CRD with issues
Post by: jay140285 on December 28, 2011, 06:14:17 PM
Well, they ended up going to Kings Jeep Cheltenham and Gloucetser as Wolovo couldnt get them in.

Looks like the Transmission Control Unit is goosed. So Jeep want £700plus to sort it out.

Had a look on ebay and no used ones about that I can see, loads for a V8.

Carlos doesnt have any either, so the search continues. 
Title: Re: Another CRD with issues
Post by: tedthefed on December 28, 2011, 07:36:48 PM
Thats the part i had replaced on mine, (467.34 + vat from the dealer) as dealer supply only.But had a bill from auto elect of £150. for sourcing the problem. Have the old one stuck on the shelf in the garage going to dismantle and see what little is inside.
Title: Re: Another CRD with issues
Post by: jay140285 on December 28, 2011, 07:41:46 PM
Yes I recall you having the problem as well. No way around it I guess, was yours plug and play?
Title: Re: Another CRD with issues
Post by: tedthefed on December 28, 2011, 07:59:18 PM
Yes plug and checked with the DRB machine and fine. But we did also try one from another jeep to confirm it was that part.
Title: Re: Another CRD with issues
Post by: jay140285 on December 28, 2011, 08:08:59 PM
There is one on ebay, £99. Think I may take the punt on that.

Waste of moolar that - go main dealer for fix.
Title: Re: Another CRD with issues

They are struggling with the cost at main dealer. Mother in laws partner hasn't worked for 12months and money tight.
Title: Re: Another CRD with issues
Post by: tedthefed on December 28, 2011, 10:59:46 PM
2nd hand one more than likely may have same problem and still may need main dealer to check with the DRB thingy.

Title: Re: Another CRD with issues

Any ideas Kev, spending £500 plus just isn't an option for them at the moment. Its not like we can lend it them at the moment as I need the scooby funds for its replacement. 
Title: Re: Another CRD with issues
Post by: Bubba on December 28, 2011, 11:31:59 PM
no i dont have any experience with such trickery     i take it you cant buy the part and self fit  ? is it somthing that has to be fitted the programmed in to the jeep ?
Title: Re: Another CRD with issues
Post by: jay140285 on December 28, 2011, 11:35:10 PM
Yes the part is nearly £500 plus vat, and I would fit it.

Hence thinking of trying a second hand one. I put a used gearbox ECU on mine when I was trying to fault find.

How much does the dealer DRB reconfig cost??
Title: Re: Another CRD with issues
Post by: Bubba on December 28, 2011, 11:37:00 PM
no idea paying a dealer is a religious taboo for me like eating health food

Think your backed into a corner here Jay.

Remember my ABS ecu woes ? Got a replacement from Carlos that was faulty (not his fault and dealt with professionally) plugged it in and the truck went into limp home mode (which wasn't the case before).  So moral of this story...truck is fine with totally busted ECU....truck is effed up with partially working one or the other way round.

Ended up @ dealer with recovery truck, left the car there,  fortunately found one on Fleabay, delivered to dealer, dealer fits and works some DRBIII & laptop magic......ecu good and accepted by truck.....happy days.

Only difference was when everything was said and done it cost 350'ish in stead of 700 new off the shelf.

Funny to hear that all ecu's on the bl**dy car cost 700 notes  :icon_rolleyes:
Title: Re: Another CRD with issues
Post by: jay140285 on December 29, 2011, 09:33:18 AM
If it was my car, I would take the risk of a used on without a moments thought,

As its not mine I want to help and save them money but don't want it to not work and cost them more in the long run.

What did the dealer charge you dutch for the DRBIII and laptop magic?

The letters at the end of the part number are the revisions and updates from  my experience of oredering parts. The replacement could be an older one with only minor differences.

You will still need to go the main dealers for the gearbox adaptations - they will not guarantee the work - catch 22 I'm afraid.

I think im in the exact same place as your mother-in-laws truck, ive been getting the mil light on, and ive noticed that it happens when i start up and put the car into gear, and as I do the jeep "jumps" into gear, mil comes on and then its in limp home mode. If I turn the car off and back on, it comes out of limp home mode, but mil stays on until i get to about 43mph, and then it goes out. This might not happen again for the next few startup times, then for no reason that I can tell it does it again.

Would you mind reporting back when you've had a bash at changing the part and letting us know the outcome?
Title: Re: Another CRD with issues

Oh shitttttt, its happened to me now too....

Now it is in limp home mode max 30mph and wont come out of it.

I'm stuck in limp home mode (it did this to me on the way to getting the MOT done  :011: )

How did you get on with changing the TCM?

Brother-in-law is a mechanic, and he thinks one reason might be a low oil level in the gearbox (although no visible signs of leaking), and suggests draining and replacing the oil.  Now Jeep say that the gearbox is a "sealed unit" and that to change the oil, guess who are the only ones that can do it....yep the stealers themselves because they are the only ones who have the dipstick to measure the level.  I've got the manual for the car, and it says:

(5) Add following initial quantity of Shell 3403 to the transmission
(a) If only fluid and filter were changed, add 5.0 L (10.6 pts.) of transmission fluid to transmission. (b) If transmission was completely overhauled, torque converter was replaced or drained, and cooler was flushed, add 7.7 L (16.3 pts.) of trans-
mission fluid to transmission.

Our thinking on this is, measure how much oil comes out, and if its less than 5l, it was too low, then fill up with 5l of new fluid and see if its fixed.

Jeep are telling me there is no drain plug on the transmission, but I was under the car the other day, and it bloody looks like there is one, can anyone confirm if this is right or not?  Jeeps way of changing the oil is to drop the pan, fit a new seal etc and then fill through the filler which is under the bonnet.  I didnt dare ask how much they wanted for doing this.

Anyone got any thoughts or suggestions on doing the transmission oil replacement and not getting the main dealer to do it?

The part has arrived today, going to the mother in laws the weekend to install and go from there. Will let you know how things go. Will PM you mate.

Its fixed, TCM located under the transmission tunnel drivers side, need to remove the centre console.

Un plugged the old TCM and put the replacement one in.

Powered car back up and job done. 1mile up the road the engine management went off and now running perfectly. All in all £100 to fix.

Title: Re: Another CRD with issues
Post by: gregwho on January 16, 2012, 04:40:48 PM
Awesome result!  Glad you got it sorted for the same price as getting the car plugged into the computer at Jeep   :icon_super:  Did you not have to get it connected to a DRB to do some sort of pairing with the new unit?  Was the centre console easy to get out?

I've just started the search (no hits on ebay) for a TCM through the spares parts network and see if there is one out there somewhere.  I'll post a message up on the wanted boards here too, fingers crossed for a £100 fix.
Title: Re: Another CRD with issues
Post by: Panic mechanic! on January 16, 2012, 04:44:38 PM
make sure if you are using ebay to search , you put in jeep 2.7 crd breaking, I have seen a few on there under that.

It was plug and play I beleive.
Title: Re: Another CRD with issues
Post by: jay140285 on January 16, 2012, 04:47:32 PM
You are correct Rob, plug and play.

Yes search for the CRD not the TCM, as there are no results under TCM.
Title: Re: Another CRD with issues
Post by: gregwho on January 16, 2012, 05:46:08 PM
Good plan guys, did an ebay search for the 2.7 breaking, and voila, a few came up.

Jay, I need to ask a favour - the guy at one of the breakers yards thinks he's got a 52 plate TCM, but the Jeep's been dismantled, so its all just bits in the back of his van at the moment.  He needs a picture to make sure he's got the right unit - would you be able to take a picture of the unit that came of your MIL's truck and send it to me so I can send it to him?  I havent looked into how to take the centre console out of mine yet, and i'm away with work for a few days, and dont want to miss this unit if its right!
