Engine light on and no rev counter

[Martinez]

mentioned this in another post. Van runs ok but light on. Rev counter not working. 
Having searched YouTube I found a vid with same symptoms but engine running rough. Turned out to be crankshaft sensor. 
Anyone have experience of this fault/problem ? Any ideas ? Sensor is cheap enough so may just go n buy one anyway

search in the search box for  crankshaft sensor   and you'll get hints on what to do and where it is.
easy to change if you know where it is on your model

It’s not crankshaft sensor. I’ve had Lexia on it and it’s the tachometer that’s knackered. Engine light was mass air sensor so got one from breakers £20 and light is out. Still working on the van though, lots still to do. Now I’ve got a problem with the headlights I bought
