OK, was having gear change issues so thought I should check the TPS settings.

 

Was sitting on 11.21v :eek:

 

When turned fully anti clockwise would go to 13.4v and fully clockwise will go to 7v at the lowest.

 

New TPS needed???

Anyone?

Dont have a real answer for you, other than that I have seen this before while watching somebody else test the TPS voltage.....similar figures to what your got...although once hooked up to conzult it was actually showing correct figures...........my "guess" would be that your testing it wrong ?

get a new multimeter,as im pretty sure this is the problem,theres no way it can read 13volts,unless it was getting a surge from somewhere,try a decent multimeter

Er, 0.4 to 0.5 volts according to my info. measured between pins A & B.

Anybody got a link on how to set this up ???

Was setting it up using this way http://www.300zx.co.uk/forums/showthread.php?t=42646&highlight=tps+setup

 

I know the multimeter is good.

 

When the Plug is taken off the TPS, the middle pin on the loose connector reads 11v. Should it?

plug stays connected with engine running place live probe to middle white pin,then earth the negative probe to the battery,then ajust it idealy 0.44v- 0.48v

Yup thats what ive been doing. and getting the readings as per my first post. :confused:

odd,if your sure your multimeter is fine,try another one just incase,or and borrow someones TPS as a try out

OK problem solved. Sort of.

 

I was taking the reading from the middle pin on the FRONT of the TPS not the connector a few inches back down. fecking idiot I am. lol

 

Now the least I can get from it is 0.50v when fully anticlockwise, so still same issue that it wont go low enough. damn it! Can the throttle bar thingy that turns (and make the voltage on the tps rise) be adjusted?

new TPS needed by the sound of it,if you have loosened both screws to it and still cant get a decent reading then id change the tps

 

0.5v should be ok,although on the autobox a slight change in TPS readings can incur slow gearchanges and hamper performance
