Title: AR35 / Autobox Sensor
Post by: JamesV6CDX on 19 April 2024, 13:27:05

The small, 2-pin sensor at the rear of the autobox. Please can someone tell me what job it does, and the consequence of it not being plugged in?

I’ve heard it called a “speed sensor” but I’m guessing that relates to sending the speed of the gearbox shaft to the TCM for shifting purposes, as I’m pretty sure the speedo is fed from the ABS system?

Finally - does anyone have or please know where I’m could buy a plug for the speed sensor and a short length of wiring? Maybe someone has an old loom in the shed? I can’t find one anyone and the plug on my loom is damaged.

Thanks chaps :y

Many thanks

Same as the oil level sensor?

It measures output shaft speed. It gets input shaft speed from RPM signal.  It compares these 2 figures, and knows what gear it thinks it is in, and if things don't correlate, throws a P0730 Incorrect Ratio  and dumps the box in limp.
