Title: Crank sensor
Post by: mrjimbo on 24 March 2008, 13:11:49: I changed my crank sensor 10 days ago but i didn't notice any difference, the starting was still quite rough/lumpy. I've just been and done a paperclip test to see if the code 19 had gone but it's still showing 19. It's done in excess of 50 starts so i'm at a loss as to whats wrong........

Anyone got any ideas ?

:(

Post by: albitz on 24 March 2008, 15:26:51: i fitted a new genuine crank sensor in jan. it started playing up last week,the only advice i could offer would be to try and beg,steal,borrow another sensor from somewhere and try it,to at least help with elimination . btw this is assuming engine is running while checking fault codes ?

Post by: mrjimbo on 24 March 2008, 16:00:48: Is there any way to test the original crank sensor ?

Although all the signs pointed to crank sensor none of the symptoms have been cured, I'm still getting code 19 and it's still not starting smoothly but it drives smooth enough so i'm not convinced that the crank sensor was the fault in the first place even though i was getting code 19. No other codes are coming up.

I've done the paperclip test with the engine running.

Post by: albitz on 24 March 2008, 16:16:30: i dont think there would be any way of testing it at home.my original one made the car difficult to start and the eml kept flashing up,did the paperclip test,got code 19.last week the car started to become slightly difficult to start and would not idle.i tried all the known things which would cause idling problems (including changing icv) and did paperclip test again and was very surprised to find code 19 again.i put the original crank sensor back on this morning and the car has started running fine.so it would appear that 2 faulty sensors wont always give the same symptoms and that a new sensor could be a duff one.it may be worth getting one from a scrappy just to see if your symptoms change by putting a different one on the car,before you try for a refund or buy another new one.

Post by: mrjimbo on 24 March 2008, 21:24:43: I need to find out if it is the crank sensor before i start paying Vauxhall labour prices. The new sensor came from LMF Vauxhall Parts, it's a pattern part but is identical to the genuine Vauxhall one that came out so i'll have a chat with them in the morning.

Post by: tmx on 28 March 2008, 19:11:42: the sensors dont last long because the exhaust manifold heats em up

i encased my sensor wire in copex tubing and filled that up with fire cement and then silicon sealant and covered it in tin foil to stop the heat eating it away!
Title: Re: Crank sensor
Post by: mrjimbo on 29 March 2008, 15:25:54: I changed the crank sensor again this morning and i've been using the car for most of the day and done well in excess of 25 starts and i've still got fault code 19, no other codes, just 19. It's begining to do my head in now.

Yep, sensor and loom connector on the other end, all in one.

Although i seam to recall some replacement ones don't have the heat reflective cover?

Which way did you route the cable, did you cable tie it away from the exhaust? If not it could touch that, melt, and cause problems :y
