Throttle position sensor

Throttle position sensor
2002 XKR
While driving car displayed code and went to idle. Disconnected and reconnected battery and car ran normally
shows Code P-1121 - pedal sensor range performance
checked PP1 and PP2 with meter
.93V @ idle to 2.87 at full throttle
.60V at idle to 4.53V at full throttle
duplicated this 2 times.
Question:
is this correct PP1 and PP2 span?
If not what is correct?
Thanks for the help

You are almost certainly living on borrowed time with this TPS.

Throttle Position Sensor
I am going to try Steve's advice and remove the unit and clean it with electric contact cleaner. It might help and at this point it can't hurt. After cleaning I will check PP1 and PP2 again and post the readings. In any case there appear to be two places on the web that rebuild throttle bodies. I will check them out. Has anyone had experience with a rebuilt TB?

This procedure might help

Also a little information on my TB trouble and rebuild

Let us know how you get on.
There'd be no harm in giving the wipers a bit of a bend to increase contact pressure.
Put it back together with sticky tape (Micropore is very good!) and check volts before re-installing it.
I found a WallWart in my box of them that gave 5V regulated so I used that.
If the output is still not near 5V at WOT then clean more aggressively - you could use chrome polish or even a very fine wet + dry.

It can only be deliberate.
I can get a non-contact programmable version made but the setup costs are around £1000 and it has proven impossible to get a bulk buy sorted.
I suggested to the manufacturer they could make good money by offering them but no interest.
I'd imagine a bit of tinkering with an op-amp could derive the second output from one linear pot.

Others have Cleaned and re-installed the TPS with mixed results, but it sure is the first thing to try.
