Throttlebody replacement issues

[David1027]

So I have a 2013 Dodge ram 1500. I’m getting two error codes.

The first error code is low reference voltage circuit B

And the other error code is throttle

The actual code is P2127 and P 0652

I changed out the throttlebody and hooked it up to a scanner to relearn. The throttlebody would not relearn. This leads me to believe that the old throttlebody may not have been the problem either. The low reference voltage I would have to say is got something to do with the whole problem.

I have looked for loose connectors. I have looked for damaged wires. I have not found anything. The truck will start an idle just fine, but there is no acceleration whatsoever. If anybody has any ideas on this, please fill me in or point me in the right direction.

Check the connector itself over very close for a bad pin,or reciever

P2127. Possible Causes:
Faulty Throttle/Pedal Position Sensor: The sensor itself may be malfunctioning and sending incorrect signals.
Wiring Issues: There could be a broken wire or a short in the wiring harness connecting the sensor to the Powertrain Control Module (PCM).
PCM Issue: In rare cases, the PCM itself might be faulty and not interpreting the sensor signals correctly.

P0652
Possible Causes and Solutions:
Failing Alternator:
The most common cause is a failing alternator that isn't charging the battery properly.
Weak or Failing Battery:
A weak battery may not be able to hold a charge or deliver the necessary voltage, according to Edmunds.
Loose or Corroded Battery Terminals or Cables:
High resistance in the cables can prevent proper voltage transfer.
Failing Voltage Regulator:
The voltage regulator controls the alternator's output, and a failure can lead to low voltage.
Defective Wiring:
Issues with the alternator wiring or connections can also cause low voltage.
