Sorry for resurrection... I'm have a similar issue with my setup. However, I don't see just 5v; I see a very short voltage range. Fully retracted it's reading 4.63v and fully extended it's reading 5.01v. I've mapped it out to 5 points (left to right: -360, -180, 0, 180,360) but RaceCapture seems to ...

I looked into this more and didn't like some of the things I found. The reason there are two sensors is for fault tolerance. The two sensor readings are active in the ECU, an algorithm calculates/compares the increasing voltage and decreasing voltage to find the position of the throttle, and if ther...

Throttle Position when there are two sensors?

My engine is drive-by-wire. The throttle body contains two separate TP sensors. Direct from the manual: There are 2 individual TP sensors within the throttle body assembly. The TP sensors are used to determine the throttle plate angle. The TP sensors provide the engine control module (ECM) with a si...

Used a calculator and it showed a 22 resistor would be 180+mA. So I'll stick to a 220 resistor. Thanks.

I'm about to tackle this and just want to make sure I'm on the right path. And I don't see that this was answered. This might be a dead thread so I might just be checking my own sanity. The Miata fuel level sender is just two wires in which resistance is measured; one grounded and one straight to th...
