Maintenance/Repairs

When I’m doing short daily trips, the speedometer seems to be normal. When I go on a long trip, the speedometer starts saying I’m going faster than I’m actually going. As the trip gets longer and longer, the reading gets higher and higher. On my last trip a couple days ago, the needle maxed out and stay there for the remainder of the trip. When I stopped it would drop down to 100km/h, but one I got moving it would soon be maxed out again. Now that I’m back home, doing short daily trips, it’s back to normal again. I’m hoping to get some ideas from others on where to start with this. I suspect there’s nothing wrong with the x24 Crankshaft Position Sensor (CKP) behind the crankshaft pulley/damper because the speedometer needle still changes with the speed. I’m suspecting that there might be a problem with the speedometer itself, but I don’t know. I did hear a clicking sound coming from the instrument panel area when I first bought the van earlier this year. The clicking seems to be gone, but now this problem. The cruise control is working good. Everything else on the instrument panel is working normal. Only the speedometer has an issue.
