have a completely custom C5 engine and transmission control harness and ECM.

The C5 drive by wire throttle position sensor is actually 2 sensors one from 0-5 volts and the other 5-0 volts.

Does anyone know if you unhook the sensor 2 wires should you still see TPS signal.

Maybe someone can do a test for me....They will need HPtuners or EFI live...this will not harm the wiring or computer.

At the TPS connector on the throttle body remove wires D,E,F which are Yellow with black strip, White, Pink. These control the internal #2 sensor.

Once they are removed hook up the scanner and turn the key on .....I am looking to see if you still get a TPS 0-100% signal. You will need to push the gas pedal to see if the TPS value changes in you scanner.

If no signal...start the car and do the same.....

I know this is a pain but maybe someone in the middle of a project could do this for me....it would be greatly appreciated...

Thanks.......oh please do not quote any GM service Manual info....I have the manual.......I need real live testing

THANKS Tom
