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.

Throttle position senson either shows 20% throttle or 100% throttle. Idle for a Grand Cherokee is roughly 12%.

This product is NOT suitable for a grand Cherokee 2004 v8 4.7l. The only thing which fits are the screws.I got it because someone left a comment before stating that it fit their Grand Cherokee 2004 but it was definitely not the case for me.

Vehicle seems to run better after installing part. I haven't driven it enough to judge the MGP, but have high hopes. If this part helps the gas mileage, it would be worth the cost of the part. Tracking on shipping was way off, but most likely due to the holiday season.

Nice packaging and good look! Time will tell regarding performance. I expect it to last a long time.

Replaced stock sensor on 2004 Jeep Grand Cherokee with 4.0. Works like it’s supposed too. I’ve had it in for a couple months and no issues. Easier to remove the throttle body to install it.
