Thanks for the reply I’ve fitted the new sensor and checked wiring this morning all looks ok apart from the plastic top part of the plug is detached so going to buy new plug + tail but still have a code for n/s/r sensor linkage and drops the rear to the floor a garage in the town is going to plug it in on Monday for me
Thanks again

Thanks I’ll have a look tomorrow I’ve picked up a sensor (copy) the code is for left rear sensor
On the maxi ap200 the volts are all around 4.91 and 4.93 so hopefully it’s the sensor and I can hook the caravan up on Thursday and go
Thanks for your input
