Default P2100 and P0222

I have P2100 open circuit to the throttle control actuator and P0222 low voltage to the TPS. I have check resistance on the control motor at 2.5 ohms, Checks ok. On my connector with ignition on I have 5v on the first 2 leads and then zero volts on the other 4 leads. I do not have 12v on any of the leads which leads me to believe I have a ground open and the reason I have P2100. I could really use a link to a wiring schematic or any helpful hints where to look, other than wires inbetween fuse box and ECM. Thank you for your help. 2008 Mazda CX7 2.3 Turbo 133K Fixer rebuilt engine.

DTC P2100
Throttle actuator circuit open

DETECTION CONDITION• PCM monitors the electronic throttle valve motor current. If the PCM detects that the electronic throttle valve motor current is below the threshold current, the PCM determines that the electronic throttle valve motor circuit has a malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• DTCs are stored in PCM memory.

POSSIBLE CAUSE
• Poor connection of throttle body connector or PCM connector
• Short to the ground between throttle body terminal F and PCM terminal 2A
• Short to the power supply between throttle body terminal F and PCM terminal 2A
• Open circuit between throttle body terminal F and PCM terminal 2A
• Short to the ground between throttle body terminal E and PCM terminal 2B
• Short to the power supply between throttle body terminal E and PCM terminal 2B
• Open circuit between throttle body terminal E and PCM terminal 2B
• Throttle actuator malfunction
• PCM malfunction

DTC P0222
TP sensor No.2 circuit low input

DETECTION CONDITION• If PCM detects that the TP sensor No.2 voltage is below 0.2 V after the ignition switch to the ON position, the PCM determines that TP circuit has a malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• DTCs are stored in the PCM memory.

POSSIBLE CAUSE
• Connector or terminal malfunction
• TP sensor malfunction
• Open circuit between throttle body terminal B and PCM terminal 2AO
• Open circuit between throttle body terminal C and PCM terminal 2AL
• Short to ground between throttle body terminal C and PCM terminal 2AL
• Short to ground between throttle body terminal B and PCM terminal 2AO
• PCM malfunction

Months go by and still working on it. I replaced the TPS, it was bad. Now I have codes 222 and 123. One side is high and the other is low. I checked the electric gas pedal. It has 6 wires: 2 wires have 5v and 2 grounds and 2 outputs that read 1.6v and 1.06 With ignition on I depress the pedal and the output is 3.9 and 3.4 respectively. I found my connector on the TPS will not click into place. It will go all the way in but not click and lock. I did check for opens/ shorts from TPS connector to ECM and found nothing. Engine will start but TPS is non responsive. Idle is rough.
