Ok, ill try that today, ill use the 100k i think. If that works out, how to i go about correcting the readings? Thanks vl400.

You wont be able to correct it with a resistor in there, its just to help protect the wideband in case of a wiring fault. Can measure the current and if none reduce the resistor to 10k and measure again - at 10k you should see something in TP too. Also try measuring (with the PCM off) the resistance from the now wideband input of the pcm to ground.
