My new car of Joshs' has taken to lighting up the Spanner Light intermittently ::)
Only code is 0340 x3. Car is an '03 ex plod manual with 130k. No history from 100k.
Is the camshaft sensor a reliable code, or just a red herring :-\
-
Only time I've seen mention of that code on here is in relation to a trapped wire or as you say, a red herring in relation to crank sensor, but usually with a load more red herrings, and no 0335
-
Double check the cable/plug is sound, and also check the cambelt timing.
Sensors should be OK 2nd hand ;)
-
:y
It had a selection of codes including 0235 and 0300 :-\ Not sure what might have been historical so left the ECU unplugged over night. The only code to come back so far is the 0340 :-\
Had a quick look, though didn't see anything out of sorts :-\
Will be servicing it in the next couple of weeks so shall proper look see :y
-
The Motronic ECUs are non volatile, so should retain codes after removal.
Its probably worth getting all systems cleared via Tech2, and then see what comes back after a few days. Not sure how far that Wood fella is from you - worth a trip?

Agreed, especially as you have no other symptoms. Had a cam sensor go on the 2.6 Estate when we first had it - symptoms stalling on idle and difficult to start, codes 0340 x 3 - Vx fitted new crank sensor (as cam sensors do not often fail) which didn't cure, then fitted new cam sensor which cured immediately. (All done under warranty)
HTH :y
-
Will try and sort the service next week, and try to see Kevin the week after :y
-
Light back on again, although still intermittent :-\
Codes via pedal trick are :
0340 x3 from yesterday
0335
0340
No trapped wires, light first came on on Christmas eve.
Could it be a sign of a dicky tensioner :-\
-
Ooooo, the 0335 made my buttocks clench.
-
Somebody shout HOUSE!
Crank sensor. :y

Sure there's a cream for that ;D

Crank sensor. :y
Need one of them then ::)
Guessing gen vx/bosch only :-\ any idea of price? Been a while since I bought one...

iirc £45 , but MUST be dealer only. Check the plug is the same in the car park before you leave though, they can't tell from the computer for some reason.
Although TheBoy said it IS the £45 One, when I got one for a late 3.2.
-
Ta muchly :y
Another job for the service then ::)
-
Bought one a few weeks ago, just under £50 on TC, iirc

Seeing as the P0340 seems to appear more often than the P0335 , it wouldnt be a case of the cam sensor causing the ecu to throw up spurious other codes, would it :-\

Crank sensor almost causes the spurious codes more often than the 0335 code itself, it seems.
It's a bit like the 2.2 cam sensor throwing auto box loopy on the 4 pots.
Crank sensor most common on the v's
Cam sensor most common on the Desmond's.

If crank sensor - would expect cutting out/difficult starting as well as code. See my post above re cam sensor ;)
-
It does take few seconds to fire :y was firing as the key turned

Well if you swap crank sensor and no improvement, you know where to look next ;)
-
Aye :y
-
Having slept on this, I think I'd be inclined to pop in a 2nd hand, known good cam sensor.
That said, being a V6, its always worth having a brand new crank sensor in the boot...
-
Manflu permitting, will swap the cam sensor from my clutchless car to try in Joshs'.
Is it on the front inside face of the 246 head, as per The Book of Blocks?

yup

:y
-
Finally got around to swapping the cam sensor from mine ::)
Driven to work and back, no lights as yet, so hopefully sorted :y
-
Cam sensor fault, not convinced, what state was the wire in.
Remember also that the cam sensor can throw a wobble if there is a timing belt issue (e.g. some slack)
-
Covered in sealant from a cover gasket change.
Did wonder about the belt side of things, as it tended to put the light on during upshifts, as the revs dropped :-\
But once on it would stay on, rather than flashing with the gear changes :-\
Changed the 246 coilpack as it was soaked and covered in orange mush, which won't have been helping...
