This is a code relating to the throttle position sensor. MAke sure the plug is connected tight. In most cases this code sets when an internal TPS issue is present

P0123, p0155, p0306


Well it really doesn't matter much. I would probably clear the codes and see which ones come back first.
Code 123 is for the throttle position sensor signal being out of range. Could be the sensor or a wiring problem.
Code 155 is for a problem with the heater circuit going to O2 sensor bank 2 sensor 1. Thats on the side with cylinder two if you have a V6 engine. Could be the sensor but its usually the lack of power for the heater.
Code 306 is for loss of power from cylinder 6 which could be mechanical, fuel, or spark related.
The three codes are not connected to each other. And trouble codes are not a statement to replace parts, only what to test.

Code P0123-THROTTLE POSITION SENSOR 1 CIRCUIT HIGH and code P0068-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION. Without having the vehicle to properly test, and based on the information I have it sounds like your throttle position sensor has kicked the bucket. Replacing the sensor with a new one should solve your problem.

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.

98 passat code # p1565 p0123 p1425 p1472 now the car will turn over but will not start. Throttle body and fuel pump are new. I have a repair manual. I do not know what the codes are telling me to fix....


1998 passat these codes are generic platform 1565 speed control command switch is out of range
P0123 Throttle position sensor/switch"A" high input
P01425 EGI glow plug secondary failure
P01472 Electro drive fan 2 operational failure

P0123 for this it means TPS is basically diconnected, and po1425 glow plug secondary failure, Why all these codes if you attempt to start the vehicle and you disconnected the Throttle body then disregard code po123 po1565 that speed control you probable stalled out and if so disregard this code. Here is what I am trying to communicate to you clear the codes.theses are not true code of the condition of the vehicle. They cannot contridict each other. If you believe these are true then trouble shoot po1425 and make sure the TPS has no broken connection and is fully seated look in the male to female connection and the harness. concentrate only on 1425 that is the reson it wont start.
