Trying to get my X reg (same as profile) back on the road

Started it a couple of weeks ago, first time, no probs, drove it around the street EML came on but expected due to not running for 9 months.

This is full of detail so forgive me but go a story to tell and someone might get a better idea

Yesterday went to start and move so as to work on for MOT and as title says it stalled, straight away.
Tried a good few times and at one point stayed running but rev's hunting. Assumed it was low on fuel, got a can full, but still the same
Brainwave, low fuel, cr@p from tank blocked fuel filter. So forced it to start on LPG

Struggled at first, engine cold, but eventually got it to go and it ran but very "lumpy".
Then suddenly the EML comes on and it ticks over and rev's as normal 
Switch it between LPG & petrol, no probs, filter OK then, but EML still on. Move it as planned and turn off.

So let's get the codes read  . Borrow reader and have another go today

First codes
P0747 Transmission Pressure Control Solenoid Stuck On
P1781 Turbo/Compressor malfunction (didnt know I had one )
P0706 Transmission Range Sensor Circuit Range/Performance
Well let's ignore these as it's been stood, reset

Start's but stall's on petrol, force start on LPG and eventually runs, but lumpy, EML comes on runs smooth, with petrol as well
Leave running to warm engine/transmission up
Read codes
P0047 HO2S Heater Control Circuit High (Bank 1 Sensor 3) 
P1781 CAN data bus ECM actual torque signal malfunction detected, WTF 

This time reset codes with engine running (dont know why but just did). Engine immed runs lumpy and stalls WTF WTF 
Start on LPG, runs lumpy, EML comes on runs smooth
Read codes again
P0043 HO2S Heater Control Circuit Low (Bank 1 Sensor 3)    (yes diff code same error  )
Ignition off, start on PETROL, stalls, start LPG, runs lumpy, EML, OK. You get the picture 
Read codes
P0747 Transmission Pressure Control Solenoid Stuck On 

Running reset, lumpy, stalls, start LPG, lumpy, EML, OK, codes
P0343 Camshaft Position Sensor Circuit High Input
P0047 HO2S Heater Control Circuit Low

Off, Reset, start LPG, lumpy, EML, OK, codes
P0343 Camshaft Position Sensor Circuit High Input
P0047 HO2S Heater Control Circuit Low

Had enough, got same prob twice, so therefore it the Cam Sensor 

Yes I know they can be "iffy" so best off swopped.

Anyone got any other idea's, One being ordered from AndyC ASAP

wow lot of information & codes there 

drove it around the street EML came on but expected due to not running for 9 months.

My 2.2 started fine after a similar amount of time   

A goosed cam sensor will cause it to crank like mad, but it should start. Its a myth about low fuel and crap in the tank, having dropped fuel tank on a 140k 2.5TD, it was totally clean.

It should run however with faulty cam sensor, think LPG is adding confusion here. I would concentrate on getting it running on petrol, as LPG will be a little lumpy when engine is cold. So lumpy running from cold start is to be expected on LPG.

Have you turned off LPG? I'm wondering if its trying to switch too early for some reason

Had the same thought, but, LPG switching to early to make it stall didnt seem to fit as it eventually started on LPG when cold, although lumpy. When the EML came on it ran perfectly ok on LPG and petrol, cold and warm

I did switch to petrol when it was cold and lumpy on LPG but it just stalled again, confused, so am i

drove it around the street EML came on but expected due to not running for 9 months.

I added this as just like your's it did run fine and the EML codes at the time where probably those strange first ones. that's why I ignored. But it might be pertinent so I mentioned it

Thanks for the suggestion anyway. Will keep it in mind when I have another go

What are you using to decode the faults?
0047 codes are for diesels, 0037 are 02 sensor codes...

[tunnie]

Was it garaged when off the road? Might be worth stripping down to cam sensor, make sure area is clean, worth checking belt tension while you are there, as its been left for some time.

As cam sensor does appear to be common code, might be worth doing the above before ordering a new one

It's one of these.


I know it can be wrong on code interpretation but normally the actual code is right

I used this website as reference just to make sure

If necessary I can call on AndyB to borrow/use his/him. If he is up for it

No it has been on drive, well covered in green algae.
Will be doing cam sensor no matter what.

Just wondered if I had come to the right conclusion

[Andy H]

When EML light comes on it is probably switching to 'limp home mode' and substituting default readings for the input it has decided is out of range.

The cam sensor has a reputation for triggering unrelated codes so it is the likely cause but I don't understand how 'limp home mode' could substitute a default value for a pulse/timing input 

I hope you don't have rodents nesting in your wiring loom...............
