Hi one and all,

Does anyone know where the speed sensor is on the 1.4 APQ engine?

My speedo has been goofing around for a day or two and has now totally given up. Ive seen posts on here from Boo saying he had the same problem and it was down to a dodgy earth. Following his instructions, i believe the earth point to be just by the distributor.

This was cleaned and reconnected but has made no difference. The wiring diagram on the sticky shows that the speed sensor goes to ground. It would be ideal to locate where the sensor earths out, and make sure the connection is good.

I have since found the speedo sensor. For those that may want to know in the future, it is located on the rear of the gearbox(bulkhead side) inline with the driveshafts and sticks straight up.

The cause of my speedo failure was caused by severe corrosion of the '+' terminal.

Before and after using contact cleaner..
