Hi
I changed crank sensor and all ok for 2 days then it stopped again TC light on and I can't read codes as spanner car symbol will not flash at all ..just stays on..I am wondered if ecu has had it..has anyone had this problem before ??

how are you doing the pedal trick 

[darren757]

Or could it be cam sensor ??

[05omegav6]

Replace the spanner light bulb, redo pedal trick and report back

To add, cam sensor on the 3.2 will always throw a code and is rare to say the least...

[darren757]

Hi

I am doing pedal test as I have done in past brake pedal and accelerator pressed and turning ignition on but not starting ..just stays on no flashing .

When I crank engine tacho needle moves so new crank sensor seems ok..I had same problem before I cleaned gear selector switch and put new Vauxhall gem crank sensor on ..ran fine for a few days then same fault with TC light on !!

Is the spanner light  on  when you turn the ignition on?

If not, it needs a new bulb before you do anything else...

Hi EML light stay on at anytime until  I crank engine then it goes out but engine doesn't start
Thanks

The SPANNER light is the one that is required for the pedal trick... Without this working you're simply pissing in the wind...

[darren757]

Hi I know spanner light is needed and I have used it this many times but it will not flash just stays on..the last time this happened eventually engine started after being left for a while then EML light worked normally again for fault reading

[Jimbob]

Hiya. Did I look at this once before a few years back?

Are you still local?
Want me to plug in and see what we can see?

[darren757]

Hi Jimbob yes you did used to be in hoole now in Wrenbury would you mind plugging in and see what the hell is going on!!when could you come over kettle will be on!!

[Jimbob]

Ahh yes I remember. As it happens I work in Crewe so can pop in on my way home?

[Jimbob]

Right, Popped over and had a look at this, without success unfortunately.

First of all, the pedal trick does not seem to work on this car currently, although historically it did.

When I arrived we had the following fault codes

Engine
P0420 - Catalyst System Efficiency Below Threshold (Bank 1)
 (01) - Present

P0430 - Catalyst System Efficiency Below Threshold (Bank 2)
 (01) - Not present

P1700 - Service Vehicle Soon Request from Transmission Control Module
 (08) - Not present

P1700 - <Unknown DTC>
 (00) - Not present

P0560 - System Voltage Malfunction
 (08) - Present

P0335 - <Unknown DTC>
 (04) - Not present

P0230 - Fuel Pump Primary Circuit Low
 (02) - Not present

P0560 - <Unknown DTC>
 (0D) - Not present

P0340 - Camshaft Position Sensor Circuit High Input
 (01) - Not present

P0340 - Camshaft Position Sensor Signal Missing
 (04) - Intermittent

Gearbox

P0730 - Gear Ratio Incorrect
 (08) - Not present

P0705 - Automatic Transmission Range Sensor Circuit Malfunction
 (08) - Not present


ABS

C0256 - <Unknown DTC>
 (00) - Present


Cleared the codes, gearbox remained clear - As expected, the car neither started or moved, happy they are historic given the selector switch issues, the lights were working perfectly today.
The ABS Code remained thoughout

Engine
P0560 - System Voltage Malfunction
 (08) - Present

P0340 - Camshaft Position Sensor Circuit High Input
 (01) - Intermittent

Live data did reveal the engine is in reduced power / limp mode/

Right, we had voltage problems, so most the starting was attempted using jump leads
I had a spare cam sensor with me, was from a 2.5, but using that nothing changed at all, same cranking, same codes afterwards
I put on the cam sensor from my 3.2, and the cranking was identical, however the codes didnt pop back, although this may be due to less cranking as it was using my battery without the car running.

I also unplugged the MAF to generate another fault code while trying to get the pedal trick to work, strangely this didnt log a code at all?

Thoughts anyone?

The only code apart from voltage which is persistant is the cam sensor, but im fairly sure weve ruled this out given they are bulletproof, and we tried 2 spares.
Crank sensor is another possibility, but im sure Darryn has a spare and has tried it, as we know these dont always give a code, and there was a historic 335 (crank sensor code) logged initially, although this didnt come back
And given the pedal trick not working, and maf removal not generating a code leads us to the last possibility that the ecu is malfunctioning to a degree, although this could be voltage related i guess.
i cleared codes, and reset learned values etc, and once the battery is fully charged, Darryn is going to try disconnecting the battery for a bit and will try again.  clutching at staws, but thats where we are.

Any other / better ideas anyone?

[Andy H]

Any other / better ideas anyone?

How much fuel is in the tank?

Did you pull any spark plugs? Any sign of petrol? Were the plugs wet with fuel? I seem to recall someone saying/writing that the V6 uses a lot of enrichment when cold so can be prone to flooding if it doesn't start first turn of the key.

[darren757]

Just to say thanks to Jimbob disputed the horrific weather kept trying to get the old girl going ..thanks

There's quarter tank of petrol even though jimbob a computer said less..again power??

I am wondering if there's a cell out on battery ..this would give under voltage dispite jump leads?

I  am charging battery ..have had all electrics on a lot and maybe it's just not enough to run all engine electrics and crank ..will advise

[Jimbob]

Just checked the ABS code in TIS,
its just limp mode.  I think thats ABS in Limp because engine is, rather than other way around.

computer reported 2 litres in tank, yet guage was about 1/4 of a tank, thought this was likely due to low voltage. I suppose chucking a few more litres in wouldnt hurt...  Guess the wet spark plug trick could help here too.

Remind me, you had tried your other crank sensor hadnt you?
