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.

Which fuse do you take out to reset your check engine light on a Chrysler Town and Country?


Instructions
    • 1

      Let the light reset itself. When the engine trouble has been fixed, a Chrysler engine resets the "Check Engine" light automatically after 40 successful runs. If it doesn't reset, the problem likely still exists.

    • 2

      Force the computer into "Successful Run" mode. Start the Chrysler and drive forward a few feet, then put it in reverse and go backward a few feet. Do this three times and shut the engine off. Crank it again to see if the light has been on.

    • 3

      Disconnect the battery for several minutes. This resets everything in the vehicle, including the clock and radio settings. Reapply the radio settings and adjust the time when the battery is reconnected.

    • 4

      Use a diagnostic scanner to clear the codes. Connect the scanner to the test port, also called the ALDL (Assembly Lineicon1.png Diagnostic Link) usually located under the dash (see Resources section). Turn the engine "On" and follow the prompts on the scanner to pull the engine codes. Select the option to clear them.

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

Where is the airbags sensor located on a 1999 grand marquis


SRS sensors are located under hood in engine compartment. They're bright orange/red and are cylindrical in shape. If your SRS lights are on, you need a special reset tool (very expensive tool) to reset. Any good shop including body shops have SRS reset tools and can reset your lights.

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.
