Sorry for the delay
My pals tach was all over the place. Can't remember the exact patterns of reading but 5k and 3k came into it and his TPS was way out of spec. As the TPS works by varying VOLTAGE to the ICU then the tacho can do strange things with a TPS that is offering up increased resistance and thus varying volts
Looks like you have been advised several times above to replace the TPS , I'm surprised you haven't done this and still wondering what the problem is. If it is the clocks then you won't know until you have fitted a new TPS as if TPS doesnt work (unlikely but theoretically possible as per unfazed comment) then the clocks are far more expensive and you could easily sell on a new unused TPS
Get on with it mate !
