Homemade TPS Sensor

Throttle Position Sensor (TPS) could be quite expensive, so, why not DIY It? :)

The stock TPS worn out due to ageing issue, so I'm keen to mod it.
In my case, I just use a 10kR pot, then, atteched it directly to the stock TPS.

Resurrected... :)

Another angle.

Yet another angle...

Testing on O'scope...

The throttle rotate fully to about 90 degrees, the pot is about 270 degrees. Hmm...
According to the o'scope, the output is about the third of the input.
So, I need to add some sort of an amplifier to it, I'm planning to use an opamp with the gain of x3.

To be continue...
