DTC P0555-00: Vacuum Sensor 2 Circuit Problem: Notes
DTC P0555:00 (PCM, SKYACTIV-G 2.0) DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0555:00 |
Vacuum sensor 2 circuit problem |
| DETECTION CONDITION |
- The PCM monitors the vacuum sensor 2 signal voltage while the ignition is switched ON. If the PCM detects the vacuum sensor 2 voltage is below 0.15 V or above 4.8 V for 5 s, the PCM determines that the vacuum sensor 2 circuit has problem.
Diagnostic support note
- This is a continuous monitor (other).
- The check engine light does not illuminate.
- FREEZE FRAME DATA is not available.
- Snapshot data is available.
- DTC is stored in the PCM memory.

| FAIL-SAFE FUNCTION POSSIBLE CAUSE |
- Vacuum sensor 2 connector or terminals malfunction
- Short to ground in wiring harness between the following terminals:
- Vacuum sensor 2 terminal A-PCM terminal 2AU
- Vacuum sensor 2 terminal C-PCM terminal 2X
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between vacuum sensor 2 terminal C and PCM terminal 2X
- Vacuum sensor 2 circuits are shorted to each other
- Open circuit in wiring harness between the following terminals:
- Vacuum sensor 2 terminal A-PCM terminal 2AU
- Vacuum sensor 2 terminal C-PCM terminal 2X
- Vacuum sensor 2 terminal B-PCM terminal 2AI
- Vacuum sensor 2 malfunction
- PCM malfunction
