19 Crank shaft sensor knackered...other code will probably go away when you fix the 19

19 is definately Crank sensor mate... there are two types for a V6 one with square edges and one which they call Oval with radiused corners. Oval one is around £50, square one around £70 from Vx.

Have a look at this link

What way would the car be if the sensor is knackered???

Er don't you mean knackered?

When mine was breaking down it would not rev over 3000 rpm and was missing terribly.
When they go completely the car will turn over but not fire.

A 19 will give starting problems, rough running, low power etc etc ... it is the signal to the ECU of the engine speed and crank position, these 2 are used to direct the fuel injection and the spark activation ...

If fuel and/or spark are at the wrong time then the engine has serious problems running, other sensors detect this and think other faults are occuring, so more codes are produced.

If it fails completely the ECU thinks the engine is stationary, so gives no sparl/fuel at all .. so it won't start !!

Fix the 19 with a new sensor, the fuel/spark occur at the right time, the other sensors become "happy" and all the codes magically dissapear ..  :y :y :y

Mine is not doing that!!! I know when the crank sensor went in my 2 litre thats what happened but at the moment all thats happening is SOMETIMES the engine management light gos on and off and the car cuts out!! But restarts after i turn off and on the key!!

Would recommend mate if you have a code 19 to change it.
Else you run the risk of being stuck somewhere

That plus a 19 indicates the sensor is starting to fail ... it will very soon fail completely .... and then you won't bwe able to start the engine ..  :(

Change it NOW ....   :y :y

Change it at the 1st hint of a 19.

Next time you may be at a very busy roundabout, or in a rush and it just wont restart!


There have been more than 1 car on here brought home on a low loader due to crank sensor!

Mine is 1 (with previous owner) , theboy is another, from the south of France!

£30 something quid on tradeclub, and 10 mins tops to change.

Just dont follow the original cable route, poke it through the pipes by the abs module away from anything hot from improved longevity  :y

i bought my mv6 with a naffed cranksensor for £200!

anyway i bought a cheap and nasty fuel parts one as an experiment to see if that fixed it yes it did but the cheap and nasty sensor lasted till the end of may! buy a genuine VX Bosch sensor as it will last 100k+

also it is dangerous driving around with a faulty sensor

often get erroneous maf code (73) when car cuts out due to 19.

Fix 19. It will shaft you. Been there, done that, always carry a spare crank sensor now ::)

Tried it again lads and i got a 73 and 31

If its the crank sensor why has she not gone into limp home mood like me 2 litre one??
Title: Re: Paperclip test shows up codes!!
Post by: Darth Loo-knee on 06 June 2008, 10:46:59
I am pretty sure 31 is because your doing the paperclip test without the car running....
Thought you said there was a 19 code?
Are you sure your reading them right mate?

Must the 2.5 be running???

To be conclusive yes...your getting a 19 when running...take the very good advice, regardless of symptoms your crank sensor will fail completely soon and then your stuffed...change it while you can before you end up stranded somewhere...

If you are getting a warning from your crank sensor think yourself lucky when mine went a couple of months ago i got no warning at all and of all places to break it chose to do it in the main entrance to the headquarters of Devon & Cornwall Police.
Never before have I wanted to be somewhere else so badly.
So was I you i'd change it right now. Also Iv'e done the same as TB and keep a spare in the car just in case.

Right lads i DID NOT have the car running when i first did the test!!! Now ive tried it with the car running and all im getting is 73

Firstly, if you have a V6 and have a 19, your crank sensor is fubar, and must be changed. No ifs/buts/it works, its knackered, end of.  It will let you down without warning.  Secondly, if you are a v6 owner, keep a spare crank sensor. When it fails, the car will cut out.  It may or may not start again (often will start after a while, but cut out again).


Right, 73, MAF.  Before condeming MAF, check for air leaks - if the engine is getting unmetered air, ecu detects this extra air and assumes low reading from MAF is a failed sensor.
