Hello,
My first post.
I need some info on setting up a throttle pot. I have access to a CD repair manual but it says that the pot need be set using JDS equipment. I assume this is Jaguar Dealer Service equipment. I figure that it may be possible to set using a multimeter with some instruction. I appreciate any help offered.
edit: I was able to find this infor from a post on an 85 XJ-12
[QUOTE]You want to probe the red and yellow wires while leaving them connected....so you'll have to tuck the probes under the wiring insulators.
With the key "on" you should show .32-.36 volts with the throttle closed. When the throttle is *slowly* opened you should see a very *smooth* increase in voltage, all the way to about 5 volts or so at full throttle. If the voltage "falls out" or is erratic, then the sensor is kapoot and/or the connector terminals are dirty/loose.
Remove the four nuts which hold the top of the throttle turret in place and lift off the throttle wheel, after disconencting the t/cable. The TPS will come with it. You'll see three tiny screws which can be loosened so as to allow the TPS to be rotated/adjusted. This is a bit frustrating as the adjustment is minute and merely tightening the screws will alter the setting. Be patient :-)[QUOTE]
Is this accurate info for the 94 XJ40 also?
Thanks,
Nick
