If it says Throttle Control Motor than it is not your Positioning sensor. obviously this car of yours does not have a throttle cable, it's 'fly by wire'

SOURCE: 1997 dodge dakota v6 engine wont start replaced

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.

When the throttle control light comes on what could be one of the problems?


electronic throttle control , Gas pedal sensors , throttle body position sensors , DC motor that controls the throttle , wiring , computer ! Should have DTC's - diagnostic trouble codes stored .

Reduced engine power message


You don't say what make an model vehicle ! But with most vehicle makes it has to do with the Throttle Actuator Control (TAC) System , electronic throttle control ! are you having reduced engine power ? There are probably DTC'S - diagnostic trouble codes stored in the PCM - engine computer .
The throttle actuator control (TAC) system is used to improve emissions, fuel economy, and driveability. The TAC system eliminates the mechanical link between the accelerator pedal and the throttle plate. The TAC system eliminates the need for a cruise control module and idle air control motor. The following is a list of TAC system components:
?€¢
The accelerator pedal assembly includes the following components:


-
The accelerator pedal


-
The accelerator pedal position (APP) sensor 1


-
The APP sensor 2


?€¢
The throttle body assembly includes the following components:


-
The throttle position (TP) sensor 1


-
The TP sensor 2


-
The throttle actuator motor


-
The throttle plate


?€¢
The engine control module (ECM)


The ECM monitors the driver demand for acceleration with 2 APP sensors. The APP sensor 1 signal voltage range is from about 0.98-4.16 volts as the accelerator pedal is moved from the rest pedal position to the full pedal travel position. The APP sensor 2 range is from about 0.49-2.08 volts as the accelerator pedal is moved from the rest pedal position to the full pedal travel position. The ECM processes this information along with other sensor inputs to command the throttle plate to a certain position.
The throttle plate is controlled with a direct current motor called a throttle actuator control motor. The ECM can move this motor in the forward or reverse direction by controlling battery voltage and/or ground to 2 internal drivers. The throttle plate is held at a 7 percent rest position using a constant force return spring. This spring holds the throttle plate to the rest position when there is no current flowing to the actuator motor.
The ECM monitors the throttle plate angle with 2 TP sensors. The TP sensor 1 signal voltage range is from about 0.5-4.25 volts as the throttle plate is moved from 0 percent to wide open throttle (WOT). The TP sensor 2 voltage range is from about 4.45-0.7 volts as the throttle plate is moved from 0 percent to WOT.
The ECM performs diagnostics that monitor the voltage levels of both APP sensors, both TP sensors, and the throttle actuator control motor circuit. It also monitors the spring return rate of both return springs that are housed internal to the throttle body assembly. These diagnostics are performed at different times based on whether the engine is running, not running, or whether the ECM is currently in a throttle body relearn procedure.
Every ignition cycle, the ECM performs a quick throttle return spring test to make sure the throttle plate can return to the 7 percent rest position from the 0 percent position. This is to ensure that the throttle plate can be brought to the rest position in case of an actuator motor circuit failure. Observe, under cold conditions, the ECM commands the throttle plate to 7 percent with the ignition ON and the engine OFF to release any ice that may have formed on the throttle plate.

When I push my gas pedal down about one inch the reduced power light comes on it don't stall just reduced power you shut the truck off restart it the light is off ,


The reduced power light is pertaining to the TAC - electronic throttle control . Is the check engine light lit ? If not still may have a DTC -diagnostic trouble code stored . You probably have a bad TPS - throttle position sensor .
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 signal, 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.

2007 Yukon XL - P01121 Throttle/Pedal Position Sensor A Circuit Range/Performance.


P1121 GMC - Throttle Position Sensor Circuit Intermittent High Voltage
This codes has nothing to do with APP - accelerator pedal position sensor . This has to do with the throttle body - TPS throttle position sensor . These have know problems ,the sensor an broken wire at throttle body , an when this happens the cruise control wont work . The throttle works by a DC motor controlled by the PCM - engine computer .

Where is the Engine Throttle Position Sensor located in my 2007 Cadillac DTS


It is located in the throttle body assembly . Your vehicle has electronic throttle control .
Throttle Body Assembly
The throttle body assembly contains the following components:
?€¢
The throttle blade


?€¢
The throttle actuator motor


?€¢
The throttle position (TP) sensor 1 and 2

The throttle body functions are similar to a conventional throttle body with the following exceptions:
?€¢
An electric motor opens and closes the throttle valve.


?€¢
The throttle blade is spring loaded in both directions and the default position is slightly open.


?€¢
There are 2 individual TP sensors within the throttle body assembly.


Oh yea it has two TPS - throttle position sensors ! An you have to replace the whole assembly !

Engine light came out and give me the code P2135


P2135 FORD Description

Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle valve movement.


The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM). In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition

Where is the TPS sensor located,2004 Nissan Titan 5.6 v-8


The 2004 nissan titan is drive by wire, meaning there is no cable to control the gas pedal to throttle.
This system is computer controlled with a motor at throttle body and pedal sensors.

the TPS throttle position sensor is located inside the throttlebody . on most of these the complete throttle body must be replaced as there is no sperate tps sensor it is complete,
i would check and make sure this is the problem . GM started making TPS replacement sensors for there throttle bodies.

I have 3 codes from my scaner p2111 p2112 p2238


P2111 - Throttle Actuator Control System Stuck Open.
P2112 - Throttle Actuator Control System Stuck Closed.
P2238 - O2 Sensor Positive Current Control Circuit Low Bank 1 Sensor 1



For the P2111 & P2112 you will need to replace the throttle body this can be pricey since the TAC is built into it. Try cleaning it good and see what happens. This can also trigger the P2238 code if its dumping fuel.
For the P2238 check the connections on the o2 sensor or replace the upstream o2 sensor that should correct it.

My 2003 chevy truck goes into limp mode and pulls code PO220.Where is the tps sensor located?


Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- No throttle response Possible Causes - Harness or connector (The TP sensor circuit is open or shorted.)
- Electric Throttle Control Actuator (or Throttle Body Motor)
- Accelerator Pedal Position Sensor (APP) P0220 Description Electric Throttle Control Actuator consists of throttle control motor, throttle position (TP)sensor, etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
When is the code detected? An unexpected voltage from the TP sensor is sent to ECM.
