Default Using a resistor to cure high TPS resistance?
EDIT: Did the math wrong... a resistor ADDS 800 to the 7,000 ohm value, not subtracts it... doh.

-Max.


I've been mucking around with my car a little, and found out that my TPS maxes out at 7K ohms. I checked the curve with a manual volt meter, and its nice and smooth, the only problem being that it has high resistance during full throttle....

I was wondering about wiring in a 800ohm resistor to the curcuit and resetting the RPM to cure this problem? A new TPS is $220, so I would love it as a temp fix for this problem. This would put my tps at 6200 ohms at full throttle, which is alright. All I would need to do is adjust the tps if this works correctly.



-Is the resistance curve on a TPS sensor linear? Will wiring in the resistor somehow skew the curve?
