I wouldn't have thought any car COULD run without crank sensor - if the ECU etc doens't know where the pistons are and when to provide the spark, surely it won't go! I may stand corrected....

Once it's seen a couple of pulses from the cam sensor it can have an educated guess at where the crank is and what speed the engine is rotating but it does need both to really know how the timing is set.

On both sides of the engine block, the passenger one is very near the oil filter, the driver's side is in the opossite postion.

Its on the passenger side just behind the oil filter.

Mines been playing up for a while, but different syptoms !

Sometimes car will crank a few times before firing, but little engine electrics light comes on !
Turn car off, re sart and its fine !
Car will always start, and even exceed 3000rpm, with light on , so from what i have been told the car isnt in limp mode !

This fault only occurs at random intervals, as i'm not in a hurry to replace the crank sensor, after Taxi Drivers description of its removal etc ! on a 2.2

Yeah my initial thought would also be crank sensor had the same problem myself strangely enough on a '94 3.0L v6. From what i remember the crank sensor is near the oil filter and not hard to replace i think there is a how 2 somewhere. From memory the sensor was about £40 from VSC. After it was replaced i havn't had any problems with the car starting. I got the sensor off fleebay nearly bought the worng one though!.

Most of these cars won't run at all without crank sensor.  2.2 petrol seems to be the exception...

I really must change mine!  ::)
Think yours was cam sensor iirc?

would the crank shaft sensor stop the spark then, when the car started the engine management light went out as normal.


Yes, because it is this that "tells" the ecu that the engine is turning.  The Ecu then uses this information, couple with the cam sensor, to fire the plugs at teh correct moment.

Yeah, it's called a distributer and rotor arm.... :D
Though no meeg'a I know off have them, well I think I saw an 8v once with one, but that may have been an Astra... I really can't remember...
My EFI V8 had one, a distributer that is, and a Rotor Arm...with plug and leads that required only one tool too.... but it only pushed out 134BHP.... :(

I'd place my bet on the C/S though....

Cheers.

OK, well that turned my knowledge of the V6 Upside down.. i thought it was, the one at the bottom of the block, at the front, below the lower pulley...  :-?
What is that one then - I assumed it was there, as it's near the CRANK, not the CAM..... :)

Cheers.

Total waste oil system! Saves changing the oil on a timed interval.  ;)
