SOURCE: Check the accelerator position sensor on the pedal!

If this is what I think it is, on the 3.5 Lit V6, you have an APS (Accelerator Position Sensor) and a TPS (Throttle Position Sensor). The accelerator pedal cable is NOT directly connected to the throttle body plate, it's connected to the APS. The APS sends its signal to the ETSCM (Electronic Throttle System Control Module) which in turn activates the ETS Motor located on the throttle body which opens/closes the throttle plate/butterfly. It's a very sofisticated electronic system. Both the APS and the TPS are known to go bad and simply replacing them is no guarantee of fixing problems in this system (often times it does, and frequently it doesn't). You should first verify there is a problem with these sensors (APS and or TPS). They are basic potentiometers (two circuits in each) which provide data to the computer regarding throttle opening for LOAD calculations (ignition timing, fuel injector pulse width, cruise control operation, etc). Best you have this system diagnosed by a professional technician who knows the system.

SOURCE: Throttle/Pedal Position Sensor/Switch B Circuit Range Performance

there is no adjustment on these tps's it's a drive by wire system. If you don't know the vehicle, dont post!
there's 2 sensors contained in the pedal sensor, and one on the throttle plate shaft, more often than not, it's the pedal sensor, and if you replaced that, it's the other one or a loose connection. did you reset the computer after replacing the pedal?

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.

P0122 is TPS signal low, which could mean you have a bad TPS, or a fault in the wiring or connector. I suspect a bad Throttle Position Sensor.

REDUCED POWER
Refer to:
• Powertrain Control Module Description for the 2.8L engine
• Powertrain Control Module Description for the 3.5L engine

Throttle Actuator Control (TAC) System
Throttle Actuator Control (TAC) Overview
The throttle actuator control (TAC) system uses vehicle electronics and components to calculate and control the position of the throttle blade. This eliminates the need for a mechanical cable attachment from the accelerator pedal to the throttle body. This system also performs the cruise control functions as well.
The TAC system components include, but are not limited to the following:
• The accelerator pedal position (APP) sensors
• The throttle body
• The powertrain control module (PCM)
Each of these components interface together to ensure accurate calculations and control of the throttle position.

Accelerator Pedal Position (APP) Sensor
The accelerator pedal position (APP) sensor is mounted on the accelerator pedal assembly. The APP is 2 individual APP sensors within one housing. There are 2 separate signal, low reference, and 5-volt reference circuits. APP sensor 1 voltage increases as the accelerator pedal is depressed. APP sensor 2 voltage decreases as the accelerator pedal is depressed.
Throttle Body Assembly
The throttle body for the throttle actuator control (TAC) system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the throttle position (TP) sensor. The TP sensor is mounted in the throttle body assembly. The TP sensor is 2 individual TP sensors within the throttle body assembly. Two separate signals, low reference, and 5-volt reference circuits are used to connect the TP sensors and the powertrain control module (PCM). TP sensor 2 signal voltage increases as the throttle opens. TP sensor 1 signal voltage decreases as the throttle opens.

Reduced Engine Power Mode
When the PCM detects a problem with the throttle actuator control (TAC) system the PCM enters one of the following Reduced Engine Power Modes:
• Acceleration Limiting--The control module will continue to use the accelerator pedal for throttle control, however the vehicle acceleration is limited.
• Limited Throttle Mode--The control module will continue to use the accelerator pedal for throttle control, however the maximum throttle opening is limited.
• Throttle Default Mode--The control module will turn OFF the throttle actuator.
• Forced Idle Mode--The control module will perform the following actions:
- Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned OFF.
- Ignore accelerator pedal input.
• Engine Shutdown Mode--The control module will disable fuel and de-energize the throttle actuator.

Have you had it checked for DTC'S - diagnostic trouble codes ?

DTC P2176
The commanded throttle position (TP) is compared to the actual TP. Both values should be within a calibrated range of each other. The powertrain control module (PCM) continuously monitors the commanded and actual TPs. If the values are greater than the calibrated range, DTC P2176 sets.
--------------------------------------------------------------------------------
DTC P2138
The accelerator pedal position (APP) sensors 1 and 2 are located within the accelerator pedal assembly. Each sensor has the following circuits:
• A 5-volt reference circuit
• A low reference circuit
• A signal circuit
This provides the powertrain control module (PCM) with a signal voltage proportional to accelerator pedal movement. The APP sensor 1 signal voltage at rest position is near the low reference and increases as the pedal is actuated. The APP sensor 2 signal voltage at rest position is near the 5-volt reference and decreases as the pedal is actuated.
DTC P2135
The throttle actuator control (TAC) assembly has 2 throttle position (TP) sensors mounted within the assembly. The powertrain control module (PCM) provides individual signal, ground, and 5-volt reference circuits to each sensor. Both sensors operate within a voltage range between 0.35-4.65 volts. When the throttle is opened from 0-100 percent, one sensor signal voltage increases while the other decreases. The signal circuit for TP sensor 1 is referenced to ground, and the signal circuit for TP sensor 2 is pulled up to 5 volts within the PCM.

I have an 2006 lincoln navigator and i had 2 codes p2104 and p2112 i changed #2 spark plug and coil then i got a fail safe mode turned truck off then back on then went away then i got the two codes p2104...


Hi, there is a post here on this issue: http://www.fordf150.net/forums/viewtopic.php?t=50060&highlight=p2104

Since you have already changed the TPS, I assume you also cleaned the throttle body? Is the throttle actuating smoothly? If not, make any repairs needed to make it smooth and easy to rotate the throttle.
If the throttle is good, then test the accelerator position sensor per the procedure below.
Please let me know if you have any questions, and thanks for using FixYa.
OperationThe APP sensor is an input to the powertrain control module (PCM) and is used to determine the torque demand. There are 3 pedal position signals in the sensor. Signal 1, APPS1, has a negative slope (increasing angle, decreasing voltage) and signals 2 and 3, APPS2 and APPS3, both have a positive slope (increasing angle, increasing voltage). During normal operation APPS1 is used as the indication of pedal position by the strategy. The 3 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. There are 2 reference voltage circuits and 2 signal return circuits for the sensor.
Removal & Installation
  1. Disconnect the battery ground cable.
  2. Disconnect the accelerator pedal position sensor electrical connector.
  3. Remove the 3 bolts and the accelerator pedal assembly.

To install:
  1. Install the 3 bolts and the accelerator pedal assembly.
  2. Tighten the mounting bolts to 18 ft. lbs. (25 Nm).

Fig. 5.4L APP sensor connector

  1. Checking the VREF voltage to the Accelerator Pedal Sensor

    Turn the ignition switch to the off position. Disconnect the Accelerator Pedal sensor connector. Measure the voltage between pin 6, 7 (ETCREF+) and 1, 3 (ETCRTN-). The voltage should read between 4-6 volts, If not repair circuits in question.
  2. Checking the Functionality of the APP sensor.

    Turn the ignition off. Disconnect the Accelerator Pedal sensor connector. Refer to Resistance Chart:
