New throttle body and accelerator pedal. After car reaches operating temp. engine slows down and p2138 code is on.
TBW blues, THROTTLE BY WIRE
NEW PARTS FROM gm OR AFTER MARKET STUFF.
THAT IS P2 OEM FACTORY ONLY CODE.
well did you use the scan tool after all those new parts
TB and pedal
and reset all DTC then drive plenty ? to see it fail again
if yes,bad wiring. or using wrong parts.
no engine told at all
no VIN told, no RPO codes for engine. told.
lacking that it be super easy to get wrong parts, on 3 _+ engines
2,8L , 3.6, and 5.7L V8
none told. and is a pure engine EFI question
to work on any car not knowing what is there, we read the RPO tag
shows engine codes. and we buy parts only ON THAT>
all 3 TB ARE DIFFERENT.
Most of these parts have connector that lock, some are double locked, and if forced are broken.
try re-seating all TB and pedal connectors, with due care.
fully re-seated.
and wire damage.
THE SM STATES AND I QUOTE
Trouble Code: P2138 (3.6L V6 VIN 7 Auto)
Accelerator Pedal Position (APP) Sensor 1-2 Correlation
Print this code data
Trouble Code Conditions:
The battery voltage is more than 7.0 volts. The ignition is ON or the engine is operating. DTC P2138 run continuously once the above conditions are met for more than 1 second. This DTC set when one of the following conditions occur: The ECM detects that the voltage difference between APP sensor 1 and 2 is more than 0.21 volt. The ECM detects that the voltage difference between APP sensor 1 and 2 is more than 0.27 volt with a partially pressed pedal. The ECM detects that the voltage difference between APP sensor 1 and 2 is more than 1.07 volts with a fully pressed pedal. The ECM detects that the APP sensor 1 voltage is more then 1.17 when leaving the idle range and the voltage difference between APP sensor 1 and 2 is more than 0.04. Any of the above conditions exist for less than 4 seconds.

ALSO ARE YOU USING MODERN SCAN TOOL 2008 OR NEWER
SO YOU CAN SEE RELATED TRANSMISSION ERRORS./
p07XX Errors?

Have someone handy to press the gas pedal for you after the engine has warmed up well; best if driven.
While you listen at the exhaust pipe, have your helper increase the revs slowly and note whether the exhaust note changes to a hiss, instead of the sound of an engine firing.
You may have a decayed catalytic convertor and when they come apart inside, they can clog mufflers and resonators (the second, smaller muffler).
I've had this happen on more than one car and when it happened on a Fiat Strada years ago, since the routing of the system was fairly straight and made of heavier gauge stainless steel, I fired two shots with a .357 magnum into the tailpipe.
Never had another problem with it.

may be it the problem of another throttle body.also check the ignition switch.
Check all of the battery terminals and cables and check the wires on the starter/selonoid, start from the battery and follow the cable out and check all conections , clean and tighten them and if it still does it the starter/selonoid is bad and needs replacement...
SOURCE: engine temp not reaching normal operating temp
thermostat that controls coolant flow is not working properly. it is probably stuck open and needs to be replaced
Ok if you changed the idle air control and there are no certain vacuum leaks and your sure. This only means the intake intake manifold in the area of the IAC has A.carbon plugging it. B.A chunk is lodged in side the channel. I recommend cleaning your intake manifold with the best cleaner with AMSOIL or Seafoam and lets not forget the old trusty air compressor hose to to force the stuff out.
Also do the IAC reset procedure maybe the IAC was disconnected while the engine was running and this has made the PCM and the IAC out of sync.
Also the throttle position sensor needs checked as well to make sure it is idleing back and the butterfly is actually closing all the way in the throttle body. Carbon build up is common around the butterfly valve which causes it to stay open further.
Also lets not forget the Intake Air Temperature sensor.
All these items need checked and completed and eliminated from the list of what else it can be.
If I can assist you any further let me know
