Assuming it's a V6 then your crank sensor needs replacing..... Urgently!

code 19 is crank sensor.

change this ASAP, it will let you down at worst time!

dead crank sensor  = dead car!

Easy to change, follow this guide and make sure the cable is routed as suggested.

I paid about £50 but you need to identify which one you require.

is it worth getting a 2nd hand one From a Breakers?
Title: Re: misfire code 19
Post by: VXL V6 on 12 April 2008, 23:42:49
No, you won't be able to extract the cable from the loom (fitted at factory), It's usually the routing of the cable (near the manifolds) that causes the failure.

A new sensor and the routing suggested in the guide is the best solution.

No - the routing of tyhe cable makes the cable go brittle.  Buy new. Sorry.

Hence (like a few V6 owners I suspect), I never go on a long journey without a spare in the boot ;D

When replaceing make sure you cable tie the cable away from the exhaust.
