The manuals do not specify the overall resistance of the TPS, however yours would seem OK. Make sure you adjust the sensor position with the throttle fully closed, to 0.45 - 0.55 volts. I have had no trouble in achieving the mean of 0.5 volts. Refer the how too section if you have a problem with this.
