Hi there:
Sound like a electrical problem 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.

P123 on chrysler 300


Hi Marcos:
We are assuming that you are talking about DTC (Diagnostic Trouble Code) P0123 Code.

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

Symptoms may include:
- Rough idle
- High idle
- Surging, other symptoms may also be present

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 (PCM)

About the solutions, if there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, carefully inspect all wiring and connectors that lead to the TPS. More than likely the problem is with the TPS wiring. Check the voltage at the TPS (refer to a service manual for your vehicle for this specific information). If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem. Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc.

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.

P0123 Just put new Tps and it is showing this code now can adjust the TPS?


DTC P0123 - Throttle Position Sensor/Switch A Circuit High Input
This code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too high a voltage. Were codes deleted after this job? This is a code for TPS voltage high.

The sensor voltage should never be greater than 5volts. It normally reads .5 to .8 volts at idle (closed throttle). The orange and dark blue is the signal wire, black and light blue is the sensor ground, and the violet and white is the 5volt supply wire. You will need to back probe the signal wire to find the value. It is possible the signal or ground wires are open. Or the PCM is faulty.

Please can you give me the code of TPS of Chevrolet Epica 2004


There are 3 DTC codes related to the TPS....

1. P0121 - Throttle Position (TP) Sensor Performance

2. P0122 - Throttle Position (TP) Sensor Circuit Low Voltage

3. P0123 - Throttle Position (TP) Sensor Circuit High Voltage

If there is any further assistance, please let us know

GM service engine code P1870/2000 GMC Sonoma 2.2 cylinder


you jave a biggie here.
here is some info
CIRCUIT DESCRIPTION
The Powertrain Control Module (PCM) monitors the difference between engine speed and transmission output speed. In D3 drive range with the TCC engaged, the engine speed should closely match the transmission output speed. In D4 drive range, with the TCC engaged, the TCC slip speed should be -20 to +60 RPM .

When the PCM detects excessive TCC slip when the TCC should be engaged, then DTC P1870 sets. DTC P1870 is a type B DTC.

CONDITIONS FOR RUNNING THE DTC
  • No TP sensor DTCs P0122 or P0123.
  • No VSS assembly DTCs P0502 or P0503.
  • No TCC solenoid valve DTC P0740.
  • No 1-2 SS valve DTC P0753.
  • No 2-3 SS valve DTC P0758.
  • No 3-2 SS valve assembly DTC P0785.
  • No TCC PWM solenoid valve DTC P1860.
  • The engine is not in fuel cutoff.
  • The engine torque is 40-400 lb ft .
  • The TP angle is 12-50% .
  • The vehicle speed is 56-112 km/h (35-70 mph ).
  • The speed ratio is 0.64-0.95 (the speed ratio is the engine speed divided by the transmission output speed).
  • The engine speed is 1500-3500 RPM .
  • The gear range is D4.
  • The commanded gear is not 1st gear
  • The TFT is between 20-130°C (68-266°F) .
  • The shift solenoid performance diagnostic counters are zero.
