Hi,can anyone advise as to what these codes are and how serious or not.
13 o2 sensor open circuit
19 incorrect RPM signal
135 telltale(checklight)voltage low.

Test done with engine running.
Thanks

I would replace the crank sensor asap (code 19) or it could leave you stranded. Oh and only get a genuine Vauxhall one  

[dbug]

Yes - code 19 is duff crank sensor - I'd replace asap with a genuine Vx one!

change the crank sensor (code 19) or very shortly your car will start stalling in the most inconveient of places

Ok thanks,checked maintainance bit,got hotel 21's pic of crank sensor,now,it looks like it might be fairly simple to replace but no doubt someone will post back saying "whoooaah there young fella me lad....you have to........" and it'll turn out to be complicated.

Is it or am i right thinking it doesn't look too bad.
Any ballpark figures on price?

[Richard A]

Yes as said: crank sensor only from a Vauxhall dealer, £55 or £90, the shape of the plug connector denotes which one you need, there are two for 3.0/2.5 petrol.

threppence - where are you based? Might be worth filling out Location section of your profile

Are there any symptoms of a dodgy crank sensor other than whats been mentioned......for example, a slight variation in idling revs now and again.

A couple of easy things to check and free too Check in the plug wells for any oil, this can lead to weak sparks causing a missfire and can eventually kill the Dispacks. Clean out the IACV (silver cylinder front right of the plenum) with some brake cleaner and oil with a little 3in1 or duck oil. See if that stops the missfire. Still order yourself a crank sensor though

might be a daft question but what the heck,when fault codes are stored are they cleared automatically when the problem is fixed,like the alerts to coolant level,brake lights etc, or could you have a situation where the problem is fixed but the fault code is still stored.

It is this way just incase you have an intermittent fault that doesn't require you to have the codes read at the exact second the fault occours, not everyone keeps a Vx (and I use the term loosely (although not all I might add!)) mechanic folded up in the boot So the ECU keeps them for 20 or so start-ups like a short history folder does on your PC.

Thanks,that does help,although I'm no good with computers either,I guess i could be called a modern day Luddite!!
