With the ignition on, have you got 12V on one of the connector terminals?

Have you checked for continuity between the second terminal and the ECU terminal 34?

Also, check your TPS setting:
(for a PF09)
1. With the ECU multi-plug plugged into the ECU, turn on the ignition.
2. Connect your negative probe to ECU Pin 1
3. Connect your positive probe to ECU Pin 17
4. Adjust the sensor to read <0.35volts at idle position.

If TPS setting is OK, may be worth trying a different TPS if you've got a spare.
