DTC P1714 Throttle Position Sensor Power Supply Circuit
WARNING: This page is about a different variant/trim than selected.
DTC DETECTING CONDITION:
The power supply circuit of accelerator pedal position sensor is open or shorted.
TROUBLE SYMPTOM:
- Shift point is too high or too low.
- Excessive shift shock
- Tight corner braking phenomenon occurs.
WIRING DIAGRAM:
RESISTANCE CHART
| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK HARNESS CONNECTOR BETWEEN TCM AND ACCELERATOR PEDAL POSITION SENSOR.
|
Is the resistance less than 1 Ω? | Go to step 2. | Repair the open circuit of harness between TCM and accelerator pedal position sensor connector, and the poor contact of the connector. |
| 2 CHECK HARNESS CONNECTOR BETWEEN TCM AND ACCELERATOR PEDAL POSITION SENSOR. Measure the resistance of the harness between TCM connector and chassis ground. Connector & terminal (B54) No. 10 - Chassis ground: |
Is the resistance more than 1 MΩ? | Go to step 3. | Repair the short circuit of harness between TCM and accelerator pedal position sensor connector. |
3 CHECK HARNESS CONNECTOR BETWEEN TCM AND ECM.
|
Is the voltage 4.6 - 5.4 V? | Go to step 4. | Even if the SPORT indicator light is blinking, the circuit is in normal condition at this time. A temporary poor contact of connector or harness may be the cause. Repair the harness or connector in accelerator pedal position sensor circuit. |
| 4 CHECK POOR CONTACT. | Is there poor contact In accelerator pedal position sensor circuit? | Repair the poor contact. | Replace the TCM. < Ref. to TRANSMISSION CONTROL MODULE (TCM) . > |
