I had a very erratic rev counter, particularly at low revs. On investigation the wires were frayed coming out from the sensor. It was irreparable. Very easy to see the fault. I bought one off ebay with a good part number that looked the same. It’s on the passenger side, RHS as you look from the front. On mine the wire damage was obvious and too close to the sensor to fix. My first fitting gave no signal and then I screwed it in one turn and it was OK. Adjustment needs care because it needs to be screwed in close to the flywheel without hitting it. IVECO 4861291 The first one up on eBay is £43 and looks like mine. Bear in mind that my engine is a 2.8ltr and my clutch housing and clutch is from a 6.5 t
