Road speed sensor fault testing
Discussion
My speedo and odometer have stopped working, rovergauge also shows no road speed. I've got a 2 pin sensor on the differential type setup that is as close to the teeth as I dare.
Never tested one before so I just wanted to make sure that I'm not missing anything as I've no idea what signal these send out. Stuck the car up in the air, wired up my multimeter to the sensor and run the car in 5th gear at idle. That's fast enough to get a signal from the sensor isn't it? Flicked around the dial and no ac/dc or ohm registering. Dead isn't it?
I've just checked the grey and black wires going from the sensor plug to the box under the dashboard and they showed fairly good continuity considering it was a 4 meter run involving speakerwire to make a circuit
Any way of testing the little black box of bodge with zero electrical skills?
Thankingyou
