Drivetrain malfunction with codes P11c5, P2138, P11cf, and U11e7?

The last three codes you listed indicate a problem with the accelerator pedal angle sensor.

Fault text
Throttle/Pedal Position Sensor/Switch 'D' / 'E' Voltage Correlation

Fault description
Diagnosis monitors the voltages of both pedal position sensors with
respect to each other.
Malfunction monitoring conditions
The fault is detected when the voltages of both pedal sensors deviate
too far from each other.

Condition for fault

identification
Voltage precondition
- Vehicle voltage between 9V and 16V
Temperature condition
- None
Time condition
- None
Other preconditions
- None
Terminal status
- Terminal 15 on


Condition for fault memory

entry
The fault is entered immediately.

Action in service
- Replace accelerator pedal module.

Fault effect and breakdown

warning
- The engine operates in its emergency program

Driver information
Emissions warning light and engine warning light
The "U" code is a network message relating to the same sensor. In most cases, replacement of the accelerator pedal assembly resolved the issue.
The P11c5 code is related to the evaporative emission system and will not usually cause any driveability concerns.

I hope this helps.

I cannot seem to find the part number for differential pressure sensor, can you locate it?

The Venturi nozzle pressure sensor is a differential pressure sensor installed in the tank ventilation line near to the intake manifold in the engine compartment.

This differential pressure sensor in the tank ventilation line is used for diagnosis of the second discharge point of the tank ventilation system. The Venturi nozzle pressure sensor is only required in the US version.

The part number I came up with is 17137448091. After a short search, it seems this part has been discontinued by the manufacturer.

So, what am i supposed to do if that is the problem? Any TSB?

Most of the parts stores have access to part interchange information that can offer aftermarket options. Ebay is also a good place to locate hard to find parts.

I replaced the pedal with the sensor and still getting one code which has nothing to do with it. Only code i get when i drive it a bit and get the message is attached. I can tell the turbo boost is not there. I also replaced the harness to the tank vent sensor. Only thing i did before installing any parts was adjusting the waste gate length as these always get loose. Do you think its possible that this adjustment could be what is causing this boost code? Maybe i adjusted it too tight or too lose?

Yes, if the actuator rod is not set correctly it could hold the wastegate open a bit and open too much. This would affect boost performance.

Ugh, back to adjustments.

Hi,

I noticed we haven't heard from you for a few days. Have you been able to make any progress? We're interested in knowing.

Take care,

Joe
