The throttle position sensor is located on the side of the throttle body attached to the throttle shaft and held in place with two small screws, if it is bad you just replace it there is no adjustment. To reset the check engine lamp you need a OBDII scan tool which plugs into the diagnostic connector under dash on drivers side.

Resetting it will not help, as the ECM (Electronic control module will readjust thus same issue. If the engine is running sluggish at a very low idle, but fine when the RMP is increased, it is probally the pcv valve, actually the hose part that goes into the back of your Carb., check this by spraying starting fluid, ether, towards the back of fuel intake while running at idle, if it revs, Bingo! Be very carefull not to start a fire, and keep an extinguisher handy!!!

2003 sta fe hyundai give code 121


P0121 HYUNDAI - Throttle/Pedal Position Sensor/Switch 'A' Circuit Range/Performance

Possible causes - Faulty throttle position sensor - Throttle position sensor harness is open or shorted - Throttle position sensor circuit poor electrical connection - Faulty Engine Control Module (ECM) What does this mean? When is the code detected? Malfunction is detected when an excessively low or high voltage from the sensor is sent to ECM. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P0121 Hyundai Description The throttle position sensor (TPS) responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (ECM). In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the ECM. Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.

Gm code p2120


Code p2120 is accelerator pedal position sensor APP sensor 1 circuit apparently this is known as the reduced engine power syndrome and is quite common on the avalanche. There is no mechanical linkage from gas pedal to throttle body and it is quite common for the throttle position sensor located on throttle body to mess up and throw this code and also for one of the wires to the throttle position sensor to get hot become brittle and sometimes break. I would start there

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.

Check engine light came on diagnostic said it was throttle position sensor i need to find out where it is located so i can replace it


The throttle position sensor is located between the air filter box and the intake manifold. If you aren't familiar with engines, the air filter box is usually located behind the driver's side headlight. There is a rubber tunnel that runs from the air box to the intake manifold. Between the rubber tunnel and the intake manifold you will find the throttle bolted to the intake manifold. The sensor is located on the throttle.

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.

  • 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.

you can try reseting the cpu first by disconnecting both positive and ground wire from battery for about a hour or so and if that does not work. I could be the throttle position which is located on lower right side of throttle body on top of engine removes with 2 screws and one wire harness very easy to replace.And if it is the sensor then u will have to disconnect battery in order to reset the sensor with the computer.

Code p0121 TPS


THERE IS A TP SENSOR BUILT INTO THE THROTTLE ACTUATOR. THESE TRUCKS HAVE BEEN KNOWN FOR A FEW PROBLEMS IN THIS AREA. THROTTLE ACTUATOR IS NOT SERVICEABLE. THE THROTTLE BODY WILL NEED TO BE REPLACED IF IT IS PROVEN FAULTY. THE APP SENSORS ARE LOCATED IN THE GAS PEDAL MODULE. THESE SEND SIGNAL TO COMPUTER TO TELL IT WHERE YOUR FOOT IS, THEN COMPUTER SENDS COMMAND TO THROTTLE ACTUATOR TO OPEN OR CLOSE THROTTLE BASED ON THIS INPUT. THE SENSOR IN THE THROTTLE ACTUATOR DELIVERS A MESSAGE BACK TO THE COMPUTER TO TELL IT WHAT THE ACTUAL THROTTLE POSITION IS. IF THESE SIGNALS DONT MATCH(WHERE THROTTLE IS COMMANDED AND WHERE IT ACTUALLY IS)THE CHECK ENGINE LIGHT WILL ILLUMINATE AND THE VEHICLE COULD GO INTO A REDUCED POWER MODE. HOPE THIS HELPS YOU!
