Message First thing to try is bleeding the system following the procedure in the FSM. Put the front end on jack stands to get the tires off the ground. Turn the steering wheel all the way to each side and hold it there for no more than 15 seconds at a time while at 2000 RPMs. Keep the PS reservoir topped off. Do this about ten times, five for each side.

After you go for a drive and if it feels good this may be a sign that you need to purge all the ATF out of your PS system and replace it with new ATF. Yes, ATF is used in the Zs PS system, not PS fluid.

It could be your still having a problem with the speed signal getting to your ECU and more needs to be done with your gauge cluster/speedometer gauge than what you've done. My info I post regarding the speedometer board repair is mostly general info. I have a process for repairing the speedometer board that goes way beyond that info. If you feel you may need my help send me an email. Thanks.
