If I tap the Throttle Position Sensor signal line to read it from A0 on the Arduino with a 5 feet 20ga wire, will the original voltage be compromised and if so, is there a way I can add a diode or something to my tap to solve this? TY!

Tapping a TPS sensor signal voltage - will it reduce the voltage to the ECU?

Is RPM linearly proportional to TPS
