DTC P0550: Notes
DETECTION CONDITION AND POSSIBLE CAUSE (DTC P0550)
| DTC P0550 |
PSP switch circuit malfunction |
| DETECTION CONDITION |
- The PCM monitors PSP switch signal at PCM terminal 2T. If input voltage is low voltage (switch stays on) for 1 min
when the VSS is above 60.0 km/h {37.4 mph}
and ECT is above 60°C {140°F},
the PCM determines that PSP switch circuit has malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- The MIL illuminates if the PCM detects above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- The DTC is stored in the PCM memory.
