Yes, I still have the L6 ECU

I thought that to test the TPS, I'd need the ECU connected and the ignition on but engine not running as otherwise the TPS circuit wouldn't be energised and I wouldn't see any voltages?

If so, do I make the test with the ecu connected, and test on the pins on the inside of the ecu with the cover off and ignition on?

Appreciate the info BTW
