This morning i started my 300zx, took off towards work as usual, and about 300 yards down the road, my speedo needle went dead and i lost my power steering. I pulled over and turned the ignition off, then on again and hey presto...a working speedo and power steering. This happened again as i pulled out of Morrisons at lunchtime....please help :(

Sounds like a loose connection or a dying fuse maybe?

 

Possibly the speed sensor connection needs cleaning?

 

What do you think guys?

Because of the HICAS the power steering is related to the speed you are doing. This is why when you get no signal to the speedo the power steering goes.

 

I agree with bantam that it could be the sender connection or if it has a converter chip fitted it may be that.

If you have a kph/mph convertor diconect it and put the circuit

back to factory this will get rid of the problem more than likley.

If this dose not work or your car is a UK then look at the speed

sensor conections on the wireing loom at the gearbox. clean

this connector, if it still is not working run temp wires to the

spedo cluster to check that you dont have a wire earthing out

on the loom. If this is not the cause then it will be the speed sensor,

only remove this as the last resort! putting the sensor back in the gearbox appeture incorrectly will dammage the pinnion gear and possably the

speed sensor it self. The pinnion gear on the end of the speedsensor

is only plastic and can easly strip if not alined correctly.

 

Hope this helps
