hi everyone, i have moved over from the cruiser world to safari land, i have a lwb high roof 1990 td42 but need some help with TPS sensor wiring, brought the wagon after previous owner put add blue in the tank, i have just changed pipes injectors and pump and all running fine apart from auto gear change i have set the tps postion how it was on the old pump, its a 24v system 6 wire sensor, every where i have read shows 5v on the top right pin( clip at top) but im getting 7.38 without tps plugged in, with tps plugged in and moving it goes from 7.38 up to 12.36, is this just because its a 24 v system ?
