Recurring P1119 error code on 2005 2.9 CRDI

Has anyone here had the same problem as me with a Intake pressure monitor fault - P1119?

So far I have not managed to find the sensor on the engine (J3) my favoured garage (none - franchise) who are engineers not module swap monkeys have failed to nail it down also, but at £60 per hour I would rather try to do something about it myself if I can!

It happens intermittently, or regularly depending upon the journey. It is driving me nuts!

The symptoms are a cough from the engine and a plume of smoke from the exhaust - sometimes - then sluggish running until I turn the ignition off for 15 seconds then back on, a right pollava when my hands are full of steering wheel trying its best to wrestle me to a standstill!

Hope someone can give ma a pointer or two!

If you can take it to a genuine hyundai garage they will be able to either reset the fault code or replace the sensor entirely.

You're like a Terramagnet Jas!!!

Lol, i admit that's a possibility.

I just realized my Terracan FAQ has a just done 10,000 views. Thats crazy lol.

But it might also be the head gasket. The engine was used my Mercedes, they used it in the sprinter and made the 5 cylinder in to a 4, some Google searches relating your description to the Mercedes engine is head gasket failure.
Its a long shot but might save you that money if your looking at it yourself.

10,000 views??? I had no idea ... wow!

This may well explain it. I just Googled "Terracan problems" and your FAQ popped up at No.7

I suppose that means I have to remove the injectors and do a compression test? If I can fine the correct adaptor for the injector holes!

I keep getting exhaust fumes in the cabin too, do you think I should just shoot the old girl and have done with it?

Helllpppp!

No need to kill it off just yet.

As for the compression test my knowledge on doing it with the terracan is limited as ive not had personally needed to do one. But a faulty head or gasket could be the reason to the smell.

Regarding the cabin fumes all i can think off is its either the Turbo seals, which have been known to perforate and/or erode and when the cabin fan hot or cold is on it puts some of the exhaust fumes in ti the cab.
Or in some European parts of the world where its cold alot they fitted as standard a auxiliary burner. I have only come across 2 vehicles with this, this burns fuel to heat the air up quicker, providing hot warm air quickly. If the seals around this are faulty or if the unit is damaged then the unit will need to be replaced, or removed and then the A/C computer if you have climate control needs to be reset because after removal of the burner there will be a fault code that will restrict the user if the A/C system. Its is possible your vehicle could be fitted with one.

But i would check the turbocharger first &/or the seals on it. Check the jubilee clips surrounding the joining pipes as well.

Nice advice Jas!
Minor problem is that this ia all due to a blocked EGR and transfer tubes and cooler.
The fault - now I have the correct codes for my J3 engine - is in fact showing as a pressure problem in the fuel rail!
BUT - that reading is due to comparitive circiutry trying to tell the ECU that the EGR is positioned properly and allowing more unburned gasses back into the intake manifold. I f the EGR is jammed - as mine is the cycle continues until there is nowhere for the gasses to go as the pipe is clogged solid, so they are vented into the engine bay!
Clever huh!
There are three vacuum operated valves on the J3, plus the phasing sensor, pressure sensor on the fuel rail and pressure sensor on the HP Fuel pump, unless all are fully working this fault occurs.

The techies at Hyundai were very short with me to start off with, only calming down once they realised I am a qualified Mechanical Engineer. However because there is no mention of the EGR cleaning process as part of the regular service listing, they had to admit it is a problem, not just on the Terry but on all diesel cars with EGRs fitted. High mileage evhicles usually are OK, it is the town drivers who suffer most, the pipes clog up and the EGR jams, leading to exhaust gasses in the cabin! Very dangerous indeed!

I can upload the error codes for reference should they be required for the J3 engine.

:shock:
