Check Engine Light - Tcode P2106

My Check Engine light came on and registered a Tcode P2106 which stands for Throttle Actuator Control System - Limited Power. At the same time my ABS Light and my Brake warning light came on. Also, my information center reads "Engine Failsafe Mode". The truck runs like garbage, (surges, hessitates, jerky). The truck runs in Open Loop continuesly which I beleive is causing an occasional Rich Code and poor fuel economy. I've checked all the sensor output values and they seem to be in lne with factory specs. I was wandering if the ABS system could be triggering some kind of Limp In Mode causing my Check Enging Light and drivability problems. Suggestions?

    I Have a 2004 Ford Explorer 4.6L. I have a similar experience.I have Code p2106 and p0102, so i put a new tps [throttle position sensor]on it ,didnt help.I still dont know if i had to calibrate it before installing,if not,does it need a throttle actuator motor??Maf says not getting enough air volume.Still drives in fail safe mode but didnt have the power like it used to. Need Help!!

    I get the same thing on my2004 f150 5.4 with a check engine light on and when i barely release the throttle it sounds like it is going to die out but idles at about 5 or 600 rpm.

What do I need to do with the code p2106


P2106 - Throttle Actuator Control System - Forced Limited Power

Engine power and RPM's will be limited and cruise control will be disabled due to a throttle fault. This occurs when one or more throttle positions sensor readings are out of range or do not agree with each other. Sometimes this code is also set if the throttle plate cannot return to the idle position due to carbon buildup in the throttle body (you might try cleaning it). The code can also be caused by a bad mass air flow, output shaft speed, turbine speed sensor, or crank position sensor. If the throttle body is clean, operates smoothly, and no other sensors are failed, then you might have to just replace the throttle body.

P2106 P2110 P2135 P1516


Here is what meens those codes:

P2106
Throttle Actuator Control System - Forced Limited Power

P2110
Throttle Actuator Control System - Forced Limited RPM

P2135
Throttle/Pedal Position Sensor/Switch "A"/"B" Voltage Correlation

P1516
Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance

I beleive that there is, specifically for chevrolet aveo 2006 a technician service bulletins.

You should have it checked at gm dealer!!!

Start and dies, codes p061f, p2106,p2104,p2111


code p2106 refers to throttle actuator control (TAC) system--limited power mode===causes ---wiring---TAC motor---APP sensor---ECM

code o2104 refers to TAQC systems ---forced idle mode===causes wiring---TAC motor--APP sensor--ECM

code p2111 refers to TAC system --actuator stuck open ==causes ---throttle body--throttle valve tight/ sticking

code p2111 also refers to TAC system --circuit malfunction==causes wiring---short to positive--short to ground---TP sensor---ECM

code p2111 also has a 3rd section---brake vacuum---implausible signal===causes---wiring---vacuum sensor--mechanical fault

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.

This is what the code reader tells me. P161B, P0496,P2110, AND P2106 can you help me


P161B = Engine Torque Control - Limit Reached = the torque delivered by the motor has exceeded its rated value
P2106 = Throttle Actuator Control System - Forced Limited Power
and
P2110 = Throttle Actuator Control System - Forced Limited RPM = the engine overrevved , pumped more power than it was rated for and it had to be forced to slow down by closing the throttle.
All this is caused by P0496 = Evap Emmission high--- purge flow fault = the evap valve got stuck in the fully open position, pumped a lot of fuel in the motor and acted like a fully opened throttle; have it cleaned and if that doesn't fixes, replace it.

P061B, P2106, when vehicle was in drive i steped on the breaks and the car continued to roll.


Those codes have NOTHING to do with the abs system. P061B is internal control module torque calculation performance, and P2106 is throttle actuator control system - forced limited power. The issue is a dirty or failing throttle body.
