I used a code reader to find the problem, purchased the sensor, and now I am discovering that it will mean removing the throttle body? I can do it but I want to be sure that is the problem before I start.I have read that- TP sensor is often missdiagnosed, throttle body has to be replaced (can't remove the TP sensor), and that it may be a loose/dirty conection. The idle is irregular, the rpm's are up too high at times, loss of power.........any feedback would be helpfull at this point. I have even been told that I may just need to clean the throttle body out due to possible fuel contamination. Please help...eager to get started on something!

Re: 2003 CR-V Throttle Position Sensor replacement
Try cleaning the IAC (Idle Air Control valve.) by buying spray carb cleaner and removing the air cduct from the engine. On the fuel system side look into the hole and try to locate 2 holes on the side . With the engine running at about 1200 rpms, spray about 10 seconds worth of cleaner at the 2 holes. Turn the engine off. Let the cleaner soak. Then repeat procedure. The IAC can also be removed and cleaned if you wish.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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.
If you had the job done at a garage, take it back. You paid good money for a part that wasn't bad. Lets take yours for instance..A TPS code. Probably read from a code reader. Replace the TPS and still have the code. There are 3 things to check for any sensor, any code. The sensor, the wiring , and the computer/PCM. A code reader only gives you a place to look, NOT the solution..
Disconnect the wire connector to the sensor then remove the 2 screws and remove the sensor then put new one on and reset the computer with a code reader or a scan tool or take it to your local autoparts store (advance auto,autozone,ect.) and they can reset it for you at no charge to you.
This problem does sounds like it could be a badThrottle position sensor because your transmission is fully electric and it depends on the signal of the throttle position sensor and the vehicle speed sensor to operate. I would recommend that you have this vehicle put on another computer at another location like AUTO-Zone they will check code for FREE and get a second opinion. Just to make sure that the code is NOT they same and also make sure that sensor was actually changed. If it was and the code is still the same and that's the only code in the computer then there is a problem with the wiring that connects to this sensor. Good Luck and contact if you need more help.Thanks for using FIX YA
I discovered that its the throttle body sensor. Its not sensing the postion of the foot pedal. The throttle body has a sensor that is linked to your gas pedal via a cable. The spring that the repair man mentioned could be the issue. The sensor then communicates to the computer the position and then computer then applies fuel, the mass air sensor then will communicate to the computer and the computer will then allow more or less air to fuel ratio. So if your stomping on the gas and there is not any response, then your throttle body sensor is most likely going out.
