If your pedal is cable operated (not likely) then check the fire wall, just trace the cable. if it is electronic pedal then it is most likely the pedal itself

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.

1az engine idles but not acceleration.engine cuts when pedal pressed


that can possibly be a accellerator pedal fault or a faulty tps throttle position sensor that is mounted to the throttle body

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 .

Po 122 problem light on had changed sensor problem not fixed trans not shifting right horrible jurks when it shifts.


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.

P0222 and p0121 troubleshooting


FIRST AND FORMOST do not listen to any advice the totally unqualified parts guys hand out at Autozone or any other free code reader parts store, they want to sell you parts and that is all.

P0222 VOLKSWAGEN - Throttle Pedal Position Sensor/Switch 'B' Circuit Low
Possible causes- Throttle position sensor harness is open or shorted
- Throttle position sensor poor electrical connection
- Faulty Throttle position sensor
When is the code detected?An excessively low voltage from the Throttle Position Sensor (TPS) is sent to Engine Control Module (ECM).

P0121 VOLKSWAGEN - 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) When is the code detected?Malfunction is detected when an excessively low or high voltage from the sensor is sent to ECM.

Have the VW dealer complete the diagnosis on this.

I have a 2003 Jeep Liberty. My check engine light comes on frequently. The diagnositc check always says its the "Pedal Alignment Sensor". What is pedal alignment and how do I have this checked and/or...


I'm assuming that you are talkin about P0122 Code - Throttle Position Sensor/Switch A Circuit Low Input

A P0122 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V).

Did you adjust it when you installed it? If the signal value is less than .17V then the PCM sets this code. Could be an open or a short to ground in the signal circuit. Or you may have lost the 5Volt reference voltage.

Symptoms may include:
* Rough or low idle
* Stalling
* Surging
* No/little acceleration
* other symptoms may also be present

Causes: A code P0122 may mean that one or more of the following has happened:
* TPS not mounted securely
* TPS circuit short to ground or another wire
* Faulty TPS
* Damaged computer (PCM)

Possible Solutions: Some recommended troubleshooting and repair steps are:
* Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
* Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
* If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
* If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.

Hope helps (remember comment and rate this).

On a 04 camry with 2.4 ltr engine, can I replace just the throttle position sensor or do i have to replace the entire throttle body? The engine code said faulty throttle body.


I think the terms "Throttle Positon Sensor", TPS and "Throttle Body" can be misleading at least in regards to the 04 Camry.

My 04 Camry gave a diagnostic reading of P2121 for my problem "Throttle PEDAL position switch D circuit". However, we changed out the complete Throttle Body/TPS (Toyota Part #22030-0H020) that did NOT fix problem.

The 04 Camry TPS Electronic Module "Throttle Positon Sensor" is factory assembled and riveted to the side of the throttle body. The only way to service/inspect it would be to cut off or drill out the rivets. Not sure you could open the darn thing if you got it off, but that seems to be the only way Toyota sells them!!

Hopefully a new Throttle PEDAL Position Sensor (Toyota Part # 78010-33010 PEDAL ASSY, ACC)
will fix it. This is located under the dash near the accelerator pedal.

So, now I would recommend FIRST to replace the "Throttle PEDAL Positon Sensor" (it is much, much cheaper) and then the Throttle Body/TPS assembly!! Unless of course, you get a diagnostic code as you did for "faulty throttle body!!

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!
