Post by: Y26SE on 16 September 2013, 16:26:12
Hi all. ive now changed from a petrol to a diesel omega and i come with a couple of fault codes if i may

51 plate 2.2 dti with the following codes

P1635 – Glow Device Circuit General Error
P0400 Critical malfunction 2 refer to checking procedure
P1590 – Engine Running Signal High Input not present.

car runs like a bag of poo but once warmed up its seems ok.

any help in where best to look first.

Thanks

What the relative resistance of all  your glow plugs. I forget now what the codes were, but both on the Astra G TD of mine & that of my s-in-law's Astra H a code referring to glow plugs lead to me a failed glow plug.

Check to see if the resistance of all the glow plugs is more or less the same .... the one that isn't is the duff one!  :y :y

no idea on the other codes  ::) ::)

No, just stick a multimeter on resistance from the contact on top of them to earth (or for Mark zero volts - the block)  ;) ;) As said, you're looking for an odd man out reading of the four  :y

Be aware that sometimes these plugs tend to seize in the head :(

I'd also fully clean out the inlet system, to allow all the inlet sensors to work

Is there a correct procedure for this?

Ill get my meter out  :)

Any other hints on the other codes. I tried clicking on the malfunction 2
 but I got no further details and the high signal missing?

HID level sensor is upset. Sometimes it's as simple as the front sensor's arm has popped off

is the P1590 code a battery or alternator voltage issue? and the critical malfunction 2 is related to this

P0400 means maf sensor reading out of operable limits. Usually caused by an egr malfunction. Check vacuum rubbers.

P1590... check your alternator output voltage.

Just a quick question on this arm. Is it easy to see the arm on the headlight or am I looking at the fabled plastic adjusters that go

ok. Glowplug changed and found some of the nib missing and it stated ok then lumpy idle and grey rubbish smoke from the back and it wont stop being lumpy until some heat gets in the engine. would the small section of nib that's missing be an issue for my piston only a few mm missing but you can see the inner core

voltage on laptop is 12v when engine off. 13.9 idle. 14.1 at 3000 rpm. still got the 1590 signal high present

The arm is on the sensor on the front near side wishbone  ;) There's another identical sensor on the rear nearside radius (suspension) arm. They both talk to a suspension ECU somewhere to keep the headlamps level  :y



or am I looking at the fabled plastic adjusters that go
Different animal   ;)  ;)

I didnt even know they were there  :o
 thank you

Is there a sensor else where that tells the ecu the voltage output as the active data on my laptop suggest there's nothing wrong with the alternator
