  1. READ VALUE USING TECHSTREAM (THROTTLE POSITION) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Data List / All Data / Throttle Position No. 1 and Throttle Position No. 2. Check the values displayed on the Techstream. RESULT Throttle Position No. 1 (VTA1) When Accelerator Pedal Released Throttle Position No. 2 (VTA2) When Accelerator Pedal Released Throttle Position No. 1 (VTA1) When Accelerator Pedal Depressed Throttle Position No. 2 (VTA2) When Accelerator Pedal Depressed Trouble Area Proceed to 0 to 0.2 V 0 to 0.2 V 0 to 0.2 V 0 to 0.2 V VC circuit open A 4.5 to 5.0 V 4.5 to 5.0 V 4.5 to 5.0 V 4.5 to 5.0 V E2 circuit open A 0 to 0.2 V, or 4.5 to 5.0 V 2.1 to 3.1 V (Fail-safe) 0 to 0.2 V, or 4.5 to 5.0 V 2.1 to 3.1 V (Fail-safe) VTA1 circuit open or shorted to ground A 0.6 to 1.4 V (Fail-safe) 0 to 0.2 V, or 4.5 to 5.0 V 0.6 to 1.4 V (Fail-safe) 0 to 0.2 V, or 4.5 to 5.0 V VTA2 circuit open or shorted to ground A 0.5 to 1.1 V 2.1 to 3.1 V 3.2 to 4.8 V (Not fail-safe) 4.6 to 5.0 V (Not fail-safe) TP sensor circuit normal B HINT: DTC P0121 is stored when the VTA1 and VTA2 output voltages are not consistent with the sensor characteristics. Therefore, check the freeze frame data when this DTC is stored. Use the following formula to confirm the relative differences in voltage. Characteristic Sensor Output VTA2 x 0.8 is approximately equal to VTA1 + 1.11 V VTA1: Throttle Position No. 1 VTA2: Throttle Position No. 2 If DTC P0121 is output, proceed to "Check Harness and Connector (Throttle Position Sensor - ECM)". B --> See step 5 A: Go to next step
  2. CHECK HARNESS AND CONNECTOR (THROTTLE POSITION SENSOR - ECM) Disconnect the throttle with motor body assembly connector. Disconnect the ECM connector. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition B22-5 (VC) - B30-88 (VCTA) Always Below 1 ohms B22-6 (VTA) - B30-90 (VTA1) Always Below 1 ohms B22-4 (VTA2) - B30-89 (VTA2) Always Below 1 ohms B22-3 (E2) - B30-111 (ETA) Always Below 1 ohms B22-5 (VC) or B30-88 (VCTA) - Body ground Always 10 kohms or higher B22-6 (VTA) or B30-90 (VTA1) - Body ground Always 10 kohms or higher B22-4 (VTA2) or B30-89 (VTA2) - Body ground Always 10 kohms or higher NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
  3. INSPECT ECM (VC VOLTAGE) Disconnect the throttle with motor body assembly connector. Turn the ignition switch to ON. Measure the voltage according to the value(s) in the table below. Standard Voltage Tester Connection Switch Condition Specified Condition B22-5 (VC) - B22-3 (E2) Ignition switch ON 4.5 to 5.5 V TEXT IN ILLUSTRATION *a Front view of wire harness connector (to Throttle with Motor Body Assembly) NG --> See step 6 OK: Go to next step
  4. REPLACE THROTTLE WITH MOTOR BODY ASSEMBLY Replace the throttle with motor body assembly. Refer to «REMOVAL [05/2013 - ]»(ref-615228-S19667413492014050900000) . HINT: Perform "Inspection After Repair" after replacing the throttle with motor body assembly. Refer to «INITIALIZATION [05/2013 - ]»(ref-615120-S07565023022014050900000) . NEXT: Go to next step
  5. CHECK WHETHER DTC OUTPUT RECURS (THROTTLE POSITION SENSOR DTCS) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Clear the DTCs. Refer to «DTC CHECK / CLEAR [05/2013 - 01/2014]»(ref-615120-S02653872462014050900000) . Start the engine. Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern. Read the output DTCs. RESULT Result Proceed to P0120, P0121, P0122, P0123, P0220, P0222, P0223 and/or P2135 is output A No DTC is output B B --> END A --> See step 7
  6. REPLACE ECM. Refer to «REMOVAL [05/2013 - 01/2014]»(ref-615228-S17169059992014050900000)
  7. REPLACE ECM. Refer to «REMOVAL [05/2013 - 01/2014]»(ref-615228-S17169059992014050900000)

HINT

  1. These DTCs relate to the throttle position sensor.
  2. Read freeze frame data using the Techstream. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

HINT

  1. If DTC P0115, P0116, P0117 or P0118 is stored simultaneously with DTC P0125, the engine coolant temperature sensor may have an open or short circuit. Troubleshoot those DTCs first.
