2006 impala 3.5 LT check engine and service traction control? Code: P2138


DTC P2138: Accelerator Pedal Position (APP) Sensor 1-2 Correlation
Electronic throttle control problem .
The throttle actuator control (TAC) system delivers improved throttle response and greater reliability and eliminates the need for mechanical cable. The TAC system performs the following functions:
• Accelerator pedal position sensing
• Throttle positioning to meet driver and engine demands
• Throttle position sensing
• Internal diagnostics
• Cruise control functions
• Manage TAC electrical power consumption
The TAC system includes the following components:
• The accelerator pedal position (APP) sensors
• The throttle body assembly
• The engine control module (ECM)

Accelerator Pedal Position (APP) Sensor
The accelerator pedal contains 2 individual accelerator pedal position (APP) sensors within the assembly. The APP sensors 1 and 2 are potentiometer type sensors each with 3 circuits:
• A 5-volt reference circuit
• A low reference circuit
• A signal circuit
The APP sensors are used to determine the pedal angle. The engine control module (ECM) provides each APP sensor a 5-volt reference circuit and a low reference circuit. The APP sensors provide the ECM with signal voltage proportional to the pedal movement. The APP sensor 1 signal voltage at rest position is less than 1 volt and increases to more than 4 volts as the pedal is actuated. The APP sensor 2 signal voltage at rest position is less than 0.6 volt and increases to more than 2 volts as the pedal is actuated.
Search P2138 on youtube ,will show diagnostic steps .

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!!!

Check engine light sensor


DTC P2138: Accelerator Pedal Position (APP) Sensor A/B (Throttle Position Sensor D/E) Incorrect Voltage Correlation.

Accelerator pedal position (APP) sensor A and accelerator pedal position (APP) sensor B are potentiometers, and they are installed in the engine compartment.

The APP sensors A and B are operated via the throttle cable to determine the accelerator opening value when the driver presses the accelerator pedal. The accelerator pedal opening value is converted to a signal in APP sensors A and B and transmitted to the engine control module (ECM)/powertrain control module (PCM) to compute the target position. The target position signal is then transmitted to the throttle actuator control module.

APP sensor A is for the primary control, and APP sensor B is a back-up of APP sensor A in case it malfunctions. Both sensors compare their output voltage to each other for malfunction detection.

When the voltage difference of APP sensor B is out of a fixed range for a set period of time, the ECM/PCM detects a malfunction, and a DTC is stored.

What does check engine light P2138 code mean and how to fix it?


P2138 Throttle/Pedal Pos Sensor Voltage Correlation

Potential Causes of P2138 DTC It's been my experience that the wiring connector or "pig tail" on the throttle body gives problems in the form of a poor connection.The female terminals on the pigtail corrode or pull out of the connector. Possible bare wire on pigtail shorting to ground. The top cover on the throttle body distorted preventing the gears from turning properly. The electronic throttle body is faulty. The accelerator pedal sensor or its wiring failed. The engine management computer has failed. The TPS sensors were not correlating for a few seconds and the computer needs to be cycled through its relearn phase to restore active response to the throttle body, or the computer needs reprogramming at the dealer.

My Santa Fe loses exceleration and when diagnosed got code p2135. I was told there was a recall by hyundai for this. Is this right


Thanks for the inquiry.
P2135:
Throttle/Pedal Position Sensor/Switch "A"/"B" Voltage Correlation
P2106:
Throttle Actuator Control System - Forced Limited Power
I would replace the throttle pedal position sensor

Best regards,

Code p2138


P2138 is Throttle Pedal Position Sensor/ Switch D / E Voltage Correlation. Replace the Throttle Pedal Position Sensor/Switch.Remember to have the set code Cleared from the cars computer, this will turn off the check engine light and reset it. Good Luck and have a good XMASS.

01 camaro drive by wire reduced engine speed


This is what I find from other webpost..

Condition:
Some customers may comment on an MIL/SES light Illuminated with the" Reduced Engine Power" message or indicator displayed. A technician may find two or more of the following DTCs stored in the ECM:

P060E : Control Module Throttle Position (TP) System Performance

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

P2135 : Throttle Position (TP) Sensor 1-2 Correlation

P2138 : Accelerator Pedal Position (APP) Sensor 1-2 Correlation

Cause:
A battery voltage drop during the cranking cycle may cause the codes to set and place the vehicle into the reduce engine power mode.

Correction:
Test and charge the battery using the steps below.

Important: A low voltage condition may cause at least two of the following DTCs to set.

P060E : Control Module Throttle Position (TP) System Performance

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

P2135 : Throttle Position (TP) Sensor 1-2 Correlation

P2138 : Accelerator Pedal Position (APP) Sensor 1-2 Correlation


Perform a Diagnostic System Check. Refer to Diagnostic System Check - Vehicle in SI.
Check for DTCs and review the Freeze Frame/Failure Records to determine if sufficient ignition voltage was present when the DTC set.
- If the ignition voltage was low, then check for a possible battery drain. Refer to Battery Electrical Drain/Parasitic Load Test.

- If the ignition voltage was sufficient when the code set, proceed with normal SI diagnosis for the code(s) set.

Test and recharge the battery using Bulletin 02-06-03-009 or latest version on "Battery Charging Tips'.
Clear all DTCs.
