Hi there:DTC P1779 - Engine Torque Delivered to TCM Signal
Engine torque signal below lower limit delivered to TCM. I've read these occur when there is a communication problem between ECM and TCM (Transmission Control Module).
DTC P1791 - Transmission Control Module LoopThe P1779 and P1791 codes set as a result of the other DTC (P0128). When the ECM sets certain trouble codes, these codes will set in the TCM (Transmission Control Module). The TCM will also increase tranmission pressures, which results in the harsh shifting.


DTC P0123 - Throttle/Pedal Position Sensor/Switch "A" Circuit HighTP sensor signal circuit is shorted to sensor ground. TP sensor signal circuit is open (except 1996-1998 models). TP sensor VREF circuit is open between sensor and PCM. TP sensor is damaged or it failed (it may be shorted).


DTC P0222 - Throttle/Pedal Position Sensor/Switch "B" Circuit LowThe Throttle control module contains two throttle position (TP) sensors with a common 5 volt supply, a common ground, and two independent signal circuits that vary resistance according to changes in throttle plate position. The ECM measures the signal voltage from each TP sensor, which is a reduced value of the ECM 5 volt reference. As the throttle plate opens from 0% throttle to wide open throttle, the voltage on the TP sensor 1 signal increases from 0.6 (+/-0.2) volts to 4.3 (+/-0.2) volts, while the voltage on the TP sensor 2 signal decreases from 4.4 (+/-0.2) volts to 0.76 (+/-0.2) volts.

If both P0122 and P0222 are set, circuit 486 may be either open or shorted to ground.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Error code P0123 and will not shift into OD


IDK if you have more than one problem. Code P0123: throttle position sensor/switch a circuit high input. Plausible causes would include, TPS not mounted correctly, TPS not properly adjusted, Wiring to the TPS is damaged (ground wire touching another wire), or the TPS sensor is defective. Your symptoms could be caused by an electrical or a mechanical failure. First repair this code and see if it fixes your driveability issue. Please write back and let me know how you are making out, good luck.

Multiple codes on 2002 dodge durango


This many codes sounds like a wiring issue. You need to inspect all the wiring. If you have rabbits in your area, they eat wires. If not then it is likely to be a corroded or loose ground. You need to get a wiring diagram etc.

Dodge durango p0123


A P0123 code means that the computer has detected that the TPS (throttle position sensor) is reporting too high a voltage.

A code P0123 may mean that one or more of the following has happened:
  • TPS not mounted securely
  • TPS circuit short to ground or another wire
  • Faulty TPS
  • Damaged computer
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
