Vectra Crank sensor error  
Vectra Crank sensor error - Big Vern
Hi

I had a After 5 min of start stop driving and 3~5 min of steady 50mph when accelerating up to 70mph on the motorway my Vectra gave a bit of a cough, lost some power for 10-20 seconds, Engine management light came on, engine power came back ok, drove to next exit approx 2 miles with light still on but car driving normally. Turned engine off, had a look under the bonnet, where all looked ok, all belts intact levels fine no smells or leaks. Started car again, no warning light and it drove fine for the next 5 motorway miles to work.

Using the ever so technical paperclip I found that the ECU has stored a crank sensor error code (0335) however in my list of error codes acquired from www.topbuzz1.carenthusiasts.co.uk/info/fault_codes...m there is another error code called Camshaft sensor (0340) which I do NOT have.

I guess I am concerned that the sensor detected a fault as opposed to the sensor becoming faulty itself, as such I am in no immediate rush to replace the sensor. So what would cause the crack sensor to log a fault (also bearing in mind the cough symptom) Would the timing belt jumping a tooth cause it?? and if so would the car appear to continue to run normally with the belt out ? Is this an early indicator that my tensioner pulley is on the way out? (Timing belt etc replaced ~25k miles ago.) Or something completely different??

Car is a 98R Vectra GLS 1.8 16v Ecotec(with Aircon)

Any ideas gratefully received.

Big Vern,

What makes you think that you don't have a camshaft sensor?

From a previous thread:-
www.honestjohn.co.uk/forum/post/index.htm?t=15600

Weshly cleaned the contacts of his cam sensor and thus solved his problem.

I would guess from your symptoms that crank sensor is faulty.(continual problem with vectras).It does what it says,senses crank position,not cambelt.Your car def has cam sensor which sits between two cam drive cogs.
Vectra Crank sensor error - Big Vern
Sorry, let me rephrase that, I do not have a Cam sensor error code logged in the ECU, I am quite sure that I do have a sensor just no fault logged from it :o)

Apologies for any confusion

UPDATE:

I have not had the problem since, I was changing the oil & filter at the weekend and had a good look for the Crank sensor. I could not find it, so I will pay somebody else to sort it out. On a side note I had a read at an article on Vectra diagnosis in Car Mechanics monthly or whatever they call it. It talks through the ISCV issue (which coincedntly I cleaned and checked for the modified x marked part only 2 months ago) The issue with the Cam and crank sensor and an issue with the Valve stems gunking up. I have been running the car on Vx fully synthetic changed every 5k miles since I got it so did not think this would be an issue, but on the advice of the article I used a double dose of Redex in the fuel and Wynns oil flush treatment when doing the oil change and the car has perked up quite a lot. Seems to have got rid of the annoying hesitation at 3000 -3200 rpm. Will reserve final judgement until I have run a couple of tanks of fuel through the car.

So I cured a problem I didn't know I had, the Crank Sensor issue hasn't reared it's head again and if it does I now know it's something I couldn't be bothered to fix myself, so off it will go to the local Mechanic :o)

If your ecu has given that code that is the prob.as a matter of info a one tooth slip on cambelt wont harm your engine but if that has happened get it checked out.the ecu only tells you if there is a problem.whether you have the correct code is another but I would heed it

Hi Vern,
Crank sensor failure is very common. Southern Carbs (0208 540 2723) are about the cheapest around. It is a fiddle to fit as it hides behind the PAS pump and the cable has to pass between the pump and block. Dont be tempted to run the cable by the exhaust.

I have a 2.0 16V Vectra CDX - 1999.

Had a similar sounding issue with mine soon after I bought it.

The rev counter was bouncing and the engine died a few times with the EMS light coming on. Sometimes it would lose power, then recover. Once it died whilst I was scooting down the M4 at about 75 ! Not funny.

Took to the local vauxhall dealer, diagnosed as faulty Lambda sensor that sense the crankshaft position. It was replaced and the garage gleefully handed it back - cost £125.

That was not the issue - the problem persisted. Eventually they took it back road tested it but found no issue. Late in the afternoon a mechanic took it out and it failed. Stalled at a junction. Got it back.....had a play, replaced the Idle Air Intake Valve. Spot on.....no problems since. That was six months ago at least - only reason it stalls now is my driving.

The Camshaft sensor was red herring. Bonus for me - I didnt pay the £180 bill to replace the IAIV.

Get them to check it out.
Vectra Crank sensor error - Andrew Moorey (Tune-Up)
Sorry, I am now confused, the lambda sensor is in the exhaust and nothing to do with the crankshaft. Your symptoms are correct for a crankshaft sensor which as they did not replace it left the original problem in place. Faults with the idle speed control valve wont affect the revcounter, crank sensor failure will. I think possibly you have been misled slightly but as the problem is solved- what matter!! £125 for a Lambda or Crank sensor from a main agent is about right so you havent been ripped off! And are they really charging £180 for an ISC valve- must put my prices up!!!!
Andrew;)

Just for info universal Lamda sensors under £40 at Cafco, and a few minutes to fit on my Carlton.

A £40 universal lambda sensor will not work on a Vectra ,system runs at a different voltage.

Hi
I have got vectra 1.8lt 16v 1998 petrol engine. I have recently had a problem with ecu light comes up while I am driving. and when I switch off the ignition and turn it on again it goes and drives allright. I took the garage and they plug it in the computer. I had 3 fault codes come out.
P0335 Crankshaft sensor
P0335 Crankshaft Sensor incorrect signal
P0351 ignition coil 1 and 4 high voltage
They said its most probably Crankshaft sensor so I bought New sensor and just get fitted by somebody I know. Which it was much cheaper than what I quoted by garage. But It didnt solved the problem. I still get ecu engine electronics immobiliser light comes on dashboard Occasionally. Could it be they didnt clear the codes.
Could you help me please? I dont know anything about using paper clip for finding codes. If anyone could explain to me how it is actually done? I dont want to pay all the time £35 for plug it in computer.
And if its not crank shaft sensor what could it be? Any detailed solving problem explanation will be very much appreciated and I will try to do it myself if I could..E mail is u.alcin@ntlworld.com
And Could it be dirty fuel injector because sometimes car is droping power while driving. Looks like it will stall but it doesnt happen yet.
Regards
Leo

As per the link Big Vern posted at the top of the page.

www.topbuzz1.carenthusiasts.co.uk/info/fault_codes...m

ALDL connector is under a cover by the handbrake. You need to short out pins 5 and 6.

And if its not crank shaft sensor what could it be?


Camshaft sensor?

Vectra Crank Cam Sensor 1996 1.8 LS Fault - Ifitaintbroke

OK, so I had this problem too, after reading various threads from around the web I was lead to belive varying things such as crankshaft sensor, camshaft sensor, air mass meter, throttle body or throttle control sensor.

Annoyingly after replacing the Cam sensor and Air mass sensor I find it is neither.

Just in case someone else happens upon this thread at a later date I recommend "if like me your not keen on spending money"

1. take the air mass sensor off, clean the small platinum pins very carefully, I used 2 cotton buds sticky taped together with some nail varnish remover as carb cleaner was not cleaning it properly due to not being able to get through the mesh grill properly.

2. check your air pipes ensure they are all tight and sealed, ensure there is no hissing noise, its very slight and you can barely hear it.

On the back of the throttle body there is a pipe fits to the side of it from the right hand side, inspect the pipe clean if needs be and ensure this is on properly, this was my fault that dam pipe had a very minor split in it and the car ran like a bang of hammers on tick over, yet drove fine with the odd jerk in normal driving, please do look at these things before you go spending £100 on new parts.

hope it helps someone :)
