Throttle position sensor

Which engine? What have you done for maintenance? Last time spark plugs replaced? Only when cold or happens when warm too?

Could be a dead spot in the tps or maybe it needs adjusting.
here is a procedure to adjust:

. Fig. 1: Throttle position sensor testing

1. Connect a digital multimeter to the throttle position sensor terminals 1 and 2. Measure resistance.
2. Insert a 0.012 in. (0.3mm) feeler gauge between throttle stop screw and throttle lever.
3. With retaining screws loosely installed, turn throttle position sensor fully clockwise, then slowly counterclockwise until digital multimeter indicates 0 ohms (continuity).
4. Tighten screws to 18 inch lbs. (2 Nm).
5. Insert a 0.035 in. (0.9mm) feeler gauge between throttle stop screw and throttle lever. Digital multimeter should now indicate an open circuit (no continuity).

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.

No. They are spliced together in the harness. Easiest way to fix it is run a new wire to the temp sensor from the power at the TPS.

- Faulty Crankshaft Position sensor
- Ignition/Distributor engine speed sensor harness is open or shorted
- Ignition/Distributor engine speed sensor circuit poor electrical connection
- Low battery charge
- Faulty Engine Control Module (ECM)

throttle position sensor/ Idle air control sensor no good one or both could be bad if you are parked can you press on the gas and the engine raises the rpm's or does it stay the same could also be accelerator cable broke if no raise in engine rpm's revs up

P0121
Throttle Position Sensor/Switch A Circuit Range/
Performance Problem. P1120 Throttle position sensor out of range
P1121. clean throttle body out good, this may fix problem. if not replace or adjust throttle position sensor. Good-Day!

Needs to have at least 3o lbs of fuel pressure,may need to rent
a gauge from your local parts house.
Plus make sure all the ground wires are attached (bell housing
bolt is where the ECM ground is,I think)

If the throttle position sensor is bad, you should get a check engine light when the engine is running.
I would check fuel pressure with a gauge at the rail to see if the pump is failing.

There is an adjustment to be made. Loosen the bolts and adjust the rotation until the specs are met.

MANUAL TRANSAXLE

1. Detach the connector from the throttle position sensor.
2. Connect an ohmmeter between terminals IDL and E.
3. Insert a 0.004 in. (0.1mm) feeler gauge between the throttle stop screw and stop lever.
4. Verify there is continuity between terminals IDL and E.
5. Then replace the feeler gauge with a 0.027 in. (0.7mm) feeler gauge, verify there is no continuity between terminals IDL and E
6. Then open the throttle wide and verify there is no continuity again between terminals IDL and E.
7. Next, connect the ohmmeter between terminals POW and E.
8. Insert a 0.004 in. (0.1mm) feeler gauge between the throttle stop screw and stop lever.
9. Verify there is no continuity between terminals POW and E.
10. Then replace the feeler gauge with 0.027 in (0.7mm), verify there is no continuity between terminals POW and E.
11. Then open the throttle wide and verify there is continuity between terminals POW and E.
12. If not as specified, adjust or replace the throttle

AUTOMATIC TRANSAXLE

1. Detach the connector from the throttle position sensor.
2. Connect an ohmmeter between the terminals IDL and E.
3. Insert a 0.004 in. (0.1mm) feeler gauge between the throttle stop screw and stop lever.
4. Verify there is continuity between terminals IDL and E.
5. Insert a 0.024 in. (0.6mm) feeler gauge between the throttle stop screw and stop lever.
6. Verify there is no continuity between terminals IDL and E.
7. Connect an ohmmeter to the throttle sensor terminals Vt and E.
8. Verify that resistance increases as throttle valve opening increase.
9. With throttle valve fully closed the resistance should be below 1 kilohm and as throttle valve is fully opened resistance should increase to approximately 5 kohms.
10. If not as specified, adjust or replace the throttle sensor.
