How to replace the Throttle position sensor

My check engine light is coming on and I found out that's because the throttle position sensor is going out. Is this the type of job that I could perform myself, and if so how? What tools are needed for this job?

If you know what the throttle valve is then you can replace the sensor, it is over 1 end of the throttle valve shaft , it is held in place by 2 screws, they may be Torx style screws, not sure on your model.

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.

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 .

Engine light on comes up as throttle positioning sensor. replaced it 2 times still comes up as throttle positioning sensor


well it looks like you should check the wireing to it. it has probably gotten the insulation from one of the wires to rubbed through causing it to short. trace the wires visually from the sensor and carefully check wires at every point they come into contact with anything

How to change a throttle position sensor on a 94 ford f150 5.0 4x4


How to Replace a Throttle Position Sensor
(DIY & Save up to $135.75 ) - Time: 2.1 hours

Parts:
1. Throttle Position Sensor - $ 55.44

Tools:
1. Scan Tool
2. Screwdriver
3. Multimeter

Procedure:
1. Locate the OBD data link connector (DLC). Refer to your owner’s manual for the specific location.
  • Tip: The OBD-I data link connector is usually located in the engine compartment near the battery or the fuse box. The OBD-II connector (post 1995 cars) is usually located beneath the instument panel next to the steering column.
2. Turn your key to the“ON” position. Do not start the engine.

3. Plug your scan tool into the OBD data link connector. Turn on the scan tool and select the appropriate steps to read the diagnostic trouble code (DTC).

Scanner plugged into OBD-II data link connector.
  • Tip: The OBD-II diagnostic trouble code (DTC) is a 5 character alphanumeric code. The first digit is a letter that indicates the component group, the second digit is OBD mandated or manufacturer specfic, the third digit is a subgroup, and the fourth and fifth digits define the component and basic problem.
  • 4. Locate the throttle position sensor.

  • Throttle position sensor

  • 5. Disconnect the electrical connector from the throttle position sensor.

  • Electrical connector removed
6. Test the resistance of the throttle position sensor (TPS) with a digital multi-meter. If the resistance is out of specifications, the TPS must be replaced.
  • 7. Remove the throttle position sensor.

    Removing sensor mounting screws

    8. Install the new throttle position sensor. Tighten the mounting screws and attach the electrical connector.
  • 9. Erase the diagnostic trouble code (DTC) with the scan tool using the“delete” or“erase” command. Road test your vehicle to see if the check engine light returns.

    Check engine light

  • Tip: If the check engine light returns, repeat the diagnostic process for additional DTCs or take your vehicle to a certified repair shop.

Engine shuts off while setting at idle.


Pumping the accelerator on a fuel injected car is usually a worthless exercise--the technique works on carbureted cars with accelerator pumps. But in your case, it may be helping a bad throttle position sensor make some idle contacts come together. the throttle position sensor has a variable resistor to tell the engine computer where the throttle opening is--and a switch to tell the computer if the throttle is open or closed as at idle. This sensor isn't cheap so I would buy a Haynes manual to help you check it out before replacing it. Some auto parts stores will "read your diagnostic trouble codes or DTC's" for free. Even if your check engine light is not on, some transitory codes can get latched in memory and help you solve the problem.
