have you tried at all to reset the program of the automatic transmission ? Always remember that even a simple connector been removed for second and re connected always needs adaptation before starting the car VW. Try to do the automatic transmission with adaptation.

Promblems P0340 P2105 P2106 P2110 P161B???? vehilce has limited power and slows down while driveing due to limited power vehicle has not ever shut off i believe it s the actuator on the throttle...


Diagnostic Test Code (DTC) P0340 is a Camshaft Position Sensor (CMP) fault. This can be caused by several things including faulty CMP sensor wiring, a defective CMP sensor, a shorted Voltage Reference (VREF) circuit or interference from high voltage ignition system problems.

The Camshaft Position (CMP) sensor is used to correlate crankshaft to camshaft position so that the Engine Control Module (ECM) can determine which cylinder is ready to be fueled by the injector. The CMP is also used to determine which cylinder is misfiring when a misfire is present.

Conditions for Setting the DTC

> CMP sensor pulse is not detected at the correct interval every 4 cylinders.
> Engine is running.


DTC P2105: Throttle Actuator Control (TAC) System - Forced Engine Shutdown
Conditions for Setting the DTC

> Ignition ON.
> The ECM detects the system is in Forced Engine Shutdown Mode.

DTC P2106: Throttle Actuator Control (TAC) System Performance - Throttle Limitation Active
Conditions for Setting the DTC

> Ignition ON.
> The ECM detects the system is in Limit Performance Mode

DTC P2110: Throttle Actuator Control (TAC) System - Forced Limited Engine Speed
Conditions for Setting the DTC

> Ignition ON.
> The ECM detects the system is in Power Management Mode.

PLEASE NOTE that these codes DO NOT NECESSARILY mean that you have a defective TAC. They DO NOT NECESSARILY mean that your TAC is malfunctioning. (although they COULD mean these things) These codes are mostly for informational purposes to let you know that the throttle system is being overridden by the engine control computer. The REASON that this override has taken place must be DIAGNOSED.

DTC P161B: Control Module Torque Performance:
The actual explaination for this one is pretty long and drawn-out. But to put things in simple terms, the trouble shooting charts pretty much say to inspect the engine for hardware problems that could allow excessive air flow. If there are no such problems found, replace the ECM.

WITH ALL OF THAT BEING SAID:

There is a Technical Service Bulletin (TSB) that addresses ALL of the codes listed above and involves replacement of the Manifold Absolute Pressure (MAP) sensor to fix the vehicle.

Here is a brief description of the bulletin:

FORENZA
Section Title: Engine
TSB No. TS 18 02228

Division: Automotive
Category: Technical

SUBJECT:
ENGINE HAS NO POWER, HESITATES, STUMBLES ON ACCELERATION, CHECK ENGINE LIGHT IS ON WITH MULTIPLE DTCS WITH P161B (CONTROL MODULE TORQUE PERFORMANCE) AS THE PRIMARY DTC

See table below for possible accompanying DTCs.
