Replaced throttle position sensor.
Replaced throttle accelerator at intake.
Performed swith on 2 sec and off 10 three times to clear system and relearn.
Tried another ECM from another lift.
Unit will not complete fast tas
Voltage at pin 5 is now.63 vlts
Showing 100 % at Throttle and Accelerator angle
Blowed out VCM and ECM connectors.

of course the one thing i should have suggested first is just letting it dry out
sometimes compressed air still wont get in the right places, you just have to let it air dry out. get a heater and a fan and let it blow on the truck. That might help.

the ETC relays can cause this problem also

ETC23 fault- Throttle sensor or wiring circuit is open or shorted. This malfunction occurs in the relation
between throttle position
sensors 1 and 2.
These sensors are internal to the TPS and are not servicable.

The most common issue causing this error is a broken wire at the TPS harness plug, usually finding the white/orange wire broken.
Also check the EGI relays in the relay box.

You can also try a TPS closed position learn
Turn ignition switch on and off
listen to the TPS and see if it is operating, you should hear it calibrate itself.
you can also try this learn proceedure
key on for 2 secs
key off for 10 secs
key on for 2 secs

this will calibrate the pedal position sensor also to the TPS
