    Then I got one off a newer model taurus maybe a 2000. It looked the same but it still has that same code. Could that be bad too? The new one one from autozone didnt have a spring inside but the tps I took from the other taurus did. Still a cose though

Replacing Throttle Position Sensor on 2004 kia sorento


My issue was my Engine light came on and I went to Autozone and O'reilly's to have them scan why my engine light came on and they told me it was putting up Error Code P0122. Looking at some forums and post was able to fix my issue on my own. Now if you replace your TPS module and the issue has not cleared you can move on to the next step in troubleshooting your error code, but in my instance the replacement fix'd mine. Here is the process I used which took about 10-15min and saved me about $300;

1. Obtain new part (I ordered my OEM part from ebay $30-$60)
2. Disconnect battery,Positive side.
3. mark the current position with a sharpie or something, you want to install in the exact position the original one was in before removing. (take a pic with your phone).
4. Disconnect the wire to the TPS module/unit.
5. Unscrew the unit (should be x2 screws, note how tight the screw is, you'll need to put same tightness when re-applying screws).
6. Put new Module/Unit in place matching the original position of the old one, just line up where you made the marks and secure with screws.
7. re-connect the wire back to the TPS module/unit.
8. re-connect battery.
9. start your car and your done.

Your check engine light should be off now for code P0122. if still on, it may be another code and if so continue troubleshooting the other codes/issues. This process resolved my Error Code P0122.

Hello dennis i replaced my tps on my sonata but still get p0122


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
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)
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 manualmag-glass_10x10.gif 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.

Changed the TPS on my 05 sedona and it reads P0122 code on scanner, after clearing the codes the check engine light wont turn off and the codes still reads P0122, maybe a bad TPS ?


this code may cause by:

TPS not mounted securely.

TPS circuit short to ground or another wire.

Faulty TPS.

Damaged computer (PCM).

to fix this code you can try this:


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.

P0122 and po700


HI. Lets start with the P0122 Code.

This code is in reference to the TPS(Throttle Position Sensor). A P0122 code essentially means that the the vehicles computer has detected that the TPS is reporting a low voltage condition. On some vehicles, the lower limit is 0.17 - 0.20 volts, respectively. This can occur if the TPS was not recently installed correctly or mis adjusted. If you have not installed it recently, than the most likely actions are to replace it, asap. Here are the most common symptoms listed below:

1. Rough idle
2. stalling during acceleration or stumbling at a red/stop light.
3. poor acceleration

If you are not experiencing those symptoms, it will most likely be intermittent and clearing the code may resolve the problem for a short time. If this should be the case, i would check the wires for rubbing against the housing or grounding faults. Again, make sure it is adjusted properly if recently installed.


The next code will be the P0700.

This is a serious transmission control unit code. You will need to take this vehicle to the dealership for the correct scan tool. You will need to extract the special codes to actual repair, correctly. Usually, the entire module will need to be replaced. A regular scanner will not pick up the TCU codes. This is a dealership code. Most Kia's are covered with a 10 year/100,000 warranty, so this should be covered.

What is Codes PO122 & PO303?


P0122 = TPS (throttle position sensor) voltage reports too low. This means that you could have a problem with the TPS, the wires to the TPS or the computer, if you have not replaced the TPS or do not want to do this work, I would take it in to a shop for this to be done. The TPS may require adjusting after replacement.
P0303= Cylinder Number 3 Missfire Detected, this means that the number 3 cylinder has miss fired, probably set this code as a result of the P0122 code. I would repair code P0122 and clear both codes. Hope this helps, let me know.
