TPS- Throttle Position Sensor
Have just fitted a 65mm TB today and had EML light come on. Scanned and got Throttle Position Sensor out of range and low input.
To sum up: TPS is stuffed isn't it?
However, I just read in Haynes that rotating it damages it so I presuming thats why it got messed up in the first place. Car is a bit lumpy/hesitant as expected with a disfunctional TPS.
When I put the new one on it should cure the problem shouldn't it? And also any tips for putting it on and NOT stuffing this one up?
Thanks

Used TPS on my TB as the 65mm TB did not come with its own TPS. I wasn't aware that they have their own TPS but the new throttle body has 3 different mounting positions for the TPS so that you can achieve the right travel (hopefully).
If worst comes to the worst I'm going to take it off again. The throttle certainly feels more alive and car has a deeper roar at WOT since its a larger TB. Also pops and bangs a lot more now. But if the TPS issue isn't resolved its coming off
Car in sig, 1.8 Zetec E focus

What car is it on?
Providing the TPS is set in the right position, I dont see why you would have a problem, the TB is still handed the same way is it? as obviously if its handed back to front you will now be showing WOT when at rest and zero throttle when its nailed.
Pics of both would be useful, or at least some slight clues about what car its from or what TB it is, as its kind of hard to make any useful suggestions while you are keeping that sort of thing secret despite beign asked about it

I'll try and get some pics up but I didn't mention before the car was on a scanner when the MIL light came on for the error codes and went into diagnostics and the TPS was correctly identifying C/T, P/T and WOT. The reference voltage was also correct, around 0.5V at idle and 4.6V at WOT which is about right. The throttle body is made particularly for the focus zetec engine 1.8 and 2.0 which are both in essence exactly the same engine bar the displacement and a few other things. same head, throttle body, inlet etc etc.
Because of the correctly identified positions of c/t, p/t and WOT I am assuming its just the TPS needs changing but I do have a slight doubt that it cannot see the full range of travel that is why it is throwing up out of range since the TB will not allow it to be mounted properly, in which case the 65mm TB is coming off.

yes there are 3 different position as I said above and I am sure that the mechanic I did it with, did it correctly. Another mechanic also came and had a look and said it was in the correct position also so I am sure of that.

well i've put a request for a TPS from Allen Fords so when that is confirmed I shall be ordering.
If it still throws up the same fault after a new TPS fitting then I may consider to look into it more, if not then the old TB is going back on.
