Is this a dv6 econetic model (vaporiser) front lh corner of the dpf cat assy? The vaporiser is only fed by a very low pressure lift pump , I'd be looking for a restricted vaporiser ,see if you can create and hold vacuum on the vaporiser fuel line connection at the vaporiser if you can it's blocked!!...

Are you sure this is a hall sensor and not magneto resistive .
Just a thought before you get two bogged down

Check the connectors on the underside of the gem module or as you call it bcm .
Sounds like he has knocked one of the snail cams than secure the connectors latched this would give you the symptoms described and usually an implausible ambient temperature reading .

The egr is quite common to short the reference voltage in these engines in fords , it usually spikes the frp giving a code respectively for the fuel pressure deviation and bloody never gives an egr code or ref voltage code in my opinion poor calibration of the dtcs . But well done for your persisten...

Hi ,a can communication error wouldn't result in hunting at idle and no throttle response.
So lets start again have you any dtcs stored?
Id be starting with basics air leaks on the intake , but let me know on the dtc,s etc and il try and assist.

Ok koeo 0.49v At idle servicable dpf around 0.5 to 0.6v At 2000 rpm if your seeing 0.8 it is loaded but requires regen If over 1 volt it will log the soot accumulation dtc with different failure mode and status this impeads drive to regen and service regen. If you want a matrix for the sensor I have...

Apologies a12xel is the engine code .
The pcm is acdelco e78.
Thanks

Im hoping someone with Vauxhall product knowledge can help me out. I have an adam with a reference voltage failure requiring a pcm . I have access to aribtes commander which will read,reset and program the pin code. I sourced a replacement online assured it had been reset with mdi so had no code pre...

Your quite right the vaporizer glow plug is supplied with battery voltage via the relay , my advice is to bridge pins 3 and 5 at the relay and volt drop the circuit using a 21w bulb to load it in place of the vaporizer. It shouldn't be to hard to prove your therory of there being a load in the wirin...

Tech all you need to do is check the negative battery terminal for presence of a bms sensor this will verify if the vehicle runs normal smart charge or smart regenerative charging. The up to 15.1v is for deep cycling only when the soc is lower than a predetermined level all this management of batter...
