Hi there need some help with this one. It has got a fault the mill light is on and no rev counter at idle but when you lift it of idle up to 1300/1400 rpm rev counter works and stop light and mill light goes out. Van runs fine, starts okay, but occasionally goes into limp mode on the road. It's has a cam shaft and crank shaft sensors but still does it. The codes are: 70 coherence between cam shaft sensor/engine speed sensor no engine speed 61 preheater circuit faulty or open circuit I have scoped the cam and crank shaft sensors but can anyone tell me if this is good? I have scoped cam shaft pictures which i can post/email if needed. thanks
