I purchased a used 2006 lly Dmax and shortly after I kept throwing a code for "Turbo Charger Position Not Recognized". I took it to the dealer and they replaced the turbo charger sensor and said that is where the problem was. Well I got the same code about 2 weeks later. After spending about a $1,000 they found nothing. The truck runs fine but the light still comes on intermittantly. I was wondering if anyone could help. Truck is completely stock...as far as I know. What would cause this?
