HiSport Throttle Position Sensor
THE ERROR CODE:
- P0120: Throttle Position Sensor/Switch A Circuit Malfunction – the voltage goes higher or lower than normal, or stutters in comparison to the “B” sensor.
- P0121: Throttle Position Sensor/Switch A Circuit Range/Performance Problem – the throttle angle doesn’t match the value expected for a specific RPM.
- P0122: Throttle Position Sensor/Switch A Circuit Low Input.
- P0123: Throttle Position Sensor/Switch A Circuit High Input – the voltage exceeds normal values.
- P0124: Throttle Pedal Position Sensor/Switch (TPS) A Circuit Intermittent – the sensor sends a number of intermittent or erratic signals within a set period
Symptoms of a Faulty Throttle Position Sensor
- An unexplainable bucking and jerking in the vehicle
- Sudden idle surges
- Sudden engine stalling without any apparent reason
- Hesitation while accelerating
- Sudden surges in speed while driving on the highway
- Intermittently flashing of check engine light for no apparent reason
- Difficulties in changing gears
- A drastic drop in fuel economy
How to Test a Throttle Position Sensor
- 1.Use a standard ohmmeter to test a switch and combination type throttle position sensor and a voltmeter to test a throttle position sensor that uses a potentiometer.
- 2.Check the resistance in various accelerator pedal positions, record the resistance
- 3.Compare against values listed as acceptable in a quality car repair manuals to determine whether or not the sensor needs to be replaced.
Is It Worth The Repair?
Some issues are worth fixing while others aren’t. In the case of a bad TPS if your car is relatively new with low miles then it has a long road ahead of it and maybe it is worth your while. Now if your vehicle has existing damages, high mileage, and now mechanical issues then it's best to sell that AS IS to avoid throwing away your hard-earned cash into that money pit.

I had a P0122 code on my 2004 Honda Accord so I purchased this, which it did clear the code. About two weeks in, my car started getting a high idle (1000-1500rpm) so I made a little adjustment to the sensor, that’s when the code P0122 came back. After much research with the high idle, I decided to just replace the whole throttle body which came with a new tps sensor and idle air control valve. Hopefully that’ll solve the high idle problem.
