Keep having those codes

[crazy_canadian]

For the second time since last month, pretty much all the same codes appear with a check engine.
First time The engine was a bit too cold and I forgot the heater ON.
But today I checked everything to be sure that's all okay.
I got these codes :
KOEO Test:
111 System checks OK
121 (O,R,M) Throttle Position (TP) sensor out of range - TPS
173 (R,M) Oxygen sensor not switching - system is or was rich - Single, Right or Rear HO2S - Fuel control
177 (M) Oxygen sensor not switching - system was rich Left or Front HO2S - Fuel control
528 (M) System shows voltage at pin 10 (is A/C on ?) or pin 30 (PNP, CPP switch) - PNP
542 (O,M) Fuel pump open, bad ground or always on - - Power / Fuel Pump Circuits

The 542 code is because I stalled the car going very uphill last night (and last month the CE light turned ON maybe the day after I stalled it too)
Both O2 sensor were replaced with new motorcraft ones last year. K&N is clean, engine runs smooth and flawlessly. EATC and radio was OFF.
Thanks!

So have you tried checking the TPS with a volt/ohm meter?

With the key off and the ohm meter connected you should see a smooth change in the ohms as you cycle the throttle through it's entire range. Any skips or jumps means a bad one.

With the key on the voltage should steadly increase from ~1v to just shy of 5v at WOT. The problem here could also be the wiring on the return signal.

You should always tackle the first code you get as this may be causing other problems. A bad TPS may throw off the logic of the PCM which may then cause O2 problems.
