Sorry C.Rocket haven't been able to track down the email of the UK owner who may have had a similar problem. As regard to sensors inm general, have you visited the website www.myisuzuparts.com ? It covers the US VX but there are lots of pics, a search engine and part lists which might help with tracking down sensors (if that is the problem) but remember the US TOD is slightly different to the JDM versions.
