To test TPS... very difficult to do on engine as you cant get at with meter. What i used to do is go to ECU unplug socket... being carefull you can un-screw the block which hold all the wires...pull out..[ carefull]...plug back in to ECU. This now allowes you to put + of your meter into pin 17...neg of you meter to earth. Ign on you should see 5v/4.5v....slowly open throttle..reading goes down to 0.5v on full throttle. Before doing this....WHEN SOCKET UNPLUGED you looking at the 35 pins, there is a longer line to the right, shorter line to the left. Pin [1] is the first in the longer line at the loom end...ie ..then pin [18] lower one...back to loom end again for pin [19] [ shorter row ] down to pin [35] so that will tell you where pin 17 is. Hope helps. While there you might as well check CTS, pins [29] and [11] you need.. with ohms only..
