DTC P2102: Notes
DTC P2102 DETECTION & CONDITION POSSIBLE CAUSES
| DTC P2102 |
Throttle actuator power supply line circuit low input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from the drive-by-wire relay when the PCM turns the drive-by-wire relay on. If the input voltage is less than 5.0 V
, the PCM determines that the drive-by-wire relay control circuit voltage is low.
Diagnostic support note
- This is a continuous monitor (CCM).
- The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
- PENDING CODE is available if the PCM detects the above malfunction condition.
- FREEZE FRAME DATA is available.
- The DTC is stored in the PCM memory.

| POSSIBLE CAUSE |
- Drive-by-wire relay malfunction
- Connector or terminal malfunction
- Open circuit in wiring harness between main relay terminal C and drive-by-wire relay terminal A
- Short to ground in wiring harness between main relay terminal C and drive-by-wire relay terminal A
- Open circuit in wiring harness between drive-by-wire relay terminal E and PCM terminal 5H
- Open circuit in wiring harness between battery positive terminal arid drive-by-wire relay terminal D
- Short to ground in wiring harness between battery positive terminal and drive-by-wire relay terminal D
- Open circuit in wiring harness between drive-by-wire relay terminal C and PCM terminal 4C
- Short to ground in wiring harness between drive-by-wire relay terminal C and PCM terminal 4C
- PCM malfunction
