Burning Smell, High Rpm, Very Slow Movement Forward.

[peterdemski]

Vehicle: 2005 Voyager 2.8 CRD

 

I got a call that on a short trip my wife noticed a burning smell right before she stopped.  Thinking it was another vehicle she went inside did her shopping and came out.  On the way home there was a burning smell and the van would go very slowly at 3K rpm's.  I assume the transmission was in limp mode and only in first gear.  Something like this happened to her one before when the alternator pulley came apart however once the alternator was replaced it did not continue so I had assumed it may have been related.  

 

No warning lights on the dash.  The fault codes are a P1130 and P0113 however I'm not sure if they are current.  I haven't pulled codes before as no CEL was lit.

 

The P0113 fault code appears to be a high input voltage to the ECM from the intake air temp sensor.  The P1130 appears to be a fuel rail pressure sensor fault.  I will of course rectify this however would this cause the behaviour noted above?  The engine appears to be running smoothly and my wife was driving around 3K on the tach.  My first instinct is to call it a transmission and or torque converter issue due to the lack of check engine lights and slow movement however as stated above when the alternator went and the serpentine belt was out a similar issue was noted and when corrected went away.

 

Any help would be greatly appreicated.

And just got a call from the wife that the vehicle is running normally again.  I'm guessing I'm in for another go at some point so I will try and rectify the fault codes and if anyone has any advice I would greatly appreciate it to try and track down the cause before we get stranded somewhere.

Hi there,

Same engine/year here.

 

I don't think the codes will be related, P1130 is a very generic fault and can be from almost anything that caused a stall or cut out, check the forum and you'll find loads, especially over winter. P0113 can be another transient fault, so again probably not connected to this issue.

 

The bit here I think I'd concentrate on is the burning smell, what type, hot engine oil (sort of normal on these big diesel beasts in hot weather, high mileage, etc) or electrical. If it's electrical then it may be worth checking the wiring looms for damage as an issue there would put the box into limp mode but it's self correcting.

And of course do absolutely make sure that you check the atf fluid level in the gearbox. If it smells burnt, and isn't pinky red it's got a problem.

 

Because in limp mode (2nd gear I believe, my old 3.3 is in it) at 3000rpm you'd still be doing a reasonable speed!!

Just a quick but very late update.  This hasn't happened again and I haven't been able to see this first hand.  While my wife has a much better nose than I do I didn't get a better description than burning.  Gearbox fluid has been checked and was at the proper level.  I appreciate the replies. 

 

As for the engine codes I believe I found the cause of P1130 which is a faulty pressure relief valve which I hope is also causing the harder starting at times.  Based on the amount of fuel coming out of the overflow for the injectors I may have a faulty injector as well but will have to do further testing when I have more time.

Sounds to me like you need to change the ATF and the filter in the transmission.

[peterdemski]

Thank you for the reply.  I will add a trans filter/fluid to my backlog.  Also haven't had this happen again.  I have read somewhere this could be caused by one of the connectors to the gearbox being loose but that seems unlikely since it hasn't happened again.

[andyb2000]

If the connector to the gearbox was loose/disconnected, it would cause all the gear selector lights to come on and a gearbox fault code (You'd need a proper reader though) to be generated, so I don't think that's the case here.

 

Hopefully it's gone away for you then, fingers crossed. An ATF and filter change are never a bad thing, don't flush or anything like that, just suck out the previous and/or drop the pan and do the replacement.

Just to let you know i had the same problem. In my case it was the 62TE gearbox running low on ATF+4. Did a flush and replaced the filter and detached the battery for a cuple of hours. Much better now and gets better and better every day.
